The aim of this study was to assess the prevalence of risk factors and cardiovascular diseases according to residents in town of Bougouni and its rural area (southern Mali). Methods: This was a retrospective descriptive study from February 2019 to March 2024. All patients who visited the “CENTRE MEDICAL DE BOUGOUNI” clinic with known or suspected heart disease during the study period were included. Data were collected from medical records. Incomplete or unusable records were excluded. Data were processed using SPS version 22 software. Results: we included 452 patients with an average age of 50 ± 19 years. High blood pression has been found in 42.70% of cases, with higher prevalence in urban areas (47.01%) than in rural areas (41.50%). Diabetes and smoking were found respectively 5.31% and 8.19% in our population. The prevalence of diabetes was higher in urban areas (5.97%) than rural area (5.35%). smoking prevalence was higher in rural areas (8.49%) than urban areas (6.72%). Alcoholism was found in 2.21% of cases with a little difference between rural area (2.24%) and urban area (2.20%). 31.63% of our patients had no cardiovascular factor. Dyspnea was the reason of consultation in 5.75% of cases and atypical precordialgia in 13.72%. Headaches and dizziness in 8.63% of cases and 21.90% of patients presented other non-specific symptoms. Diagnosis of idiopathic dilated cardiomyopathy was found in 23.45% of cases with higher prevalence in rural areas (28.30%) than urban areas (13.43%). Ischaemic heart disease accounted for 9.29% of cases with a higher prevalence in rural areas (10.38%) than in urban areas (6.71%). PPCMs accounted for 5.98% of cases, with a slight increase in urban areas (6.66%) compared with rural areas (5.68%). Rheumatic valvulopathy accounted for 2.21% of cases;2.84% in rural areas and 0.74% in urban areas. Other valvular diseases accounted for 3.76% of cases;4.73% in rural areas and 1.48% in urban areas. Right heart diseases accounted for 3.98% of cases and stroke for 1.77%. Conclusion: The prevalence of cardiovascular risk factors and heart diseases is high in the rural and urban population of the town of Bougouni and its surroundings (Mali). Excepted smoking, the prevalence of other CV risk factors is higher in urban areas, whereas the prevalence of idiopathic dilated cardiomyopathy and ischemic heart disease is higher in rural areas. These data could serve as a basis for developing tailored preventive strategies, depending on the place of residence.展开更多

Existing research has evaluated the extent of URI and explored its influencing factors, but urban-rural linkages are seldom incorporated in evaluation systems, and geographical factors are rarely recognized as the influencing factors. We construct a URI framework including regional economy, rural development, urban-rural linkage, and urban-rural gap. Based on a dataset consisting of 1,669 counties in China in 2020, we reveal the spatial pattern of URI and find a high correlation between the spatial pattern of URI and the relief degree of land surface (RDLS). Using structural equation modeling, we discover that topography has direct ( − 0.18, p < 0.001) and indirect ( − 0.17, p < 0.001) effects on URI. The indirect negative effects are mediated through the infrastructure, and the combination of localized advantages and modern technical conditions could mitigate the negative impact of topography. Finally, we identify 742 counties as lagging regions in URI, which can be clustered into eight types. Our findings could facilitate policy designing for those countries striving for integrated and sustainable development of urban and rural areas.展开更多

In this paper, Shuangliu County is taken as a case, since it is a typical fringe area of Chengdu Metropolis. Based on Landsat TM images of Chengdu City and Shuangliu County obtained in 1985, 2000 and 2004, characteristics of urban and rural spatial structure in Shuangliu County were analyzed, such as core-periphery spa-tial structure and some obvious integration trends. Then the influencing factors for the formation of urban and rural spatial structure were identified, including some natural, social, economic and political factors. According to the discussion of this paper, Shuangliu County is undergoing a key transition and reform period. Its formation of urban and rural spatial structure was affected not only by such common factors as the location, natural background, industrial transition, migra-tion, etc., but also by some unique factors such as city planning and policy guidance, which played an important role in accelerating its uneven spatial structure. The understanding of the role of the influencing factors would be useful for car-rying out spatial management and development planning of metropolis fringe area.展开更多

Using the stepwise regression analysis,we find that urbanization level,socio-economic development,education level,financial development scale and financial development efficiency have the greatest impact on the income gap between urban and rural areas. By cointegration test,it is found that there is a long-term equilibrium relationship between these five variables and the income gap between urban and rural areas. We build the state-space model to research the dynamic impact of these factors on the income gap between urban and rural areas. The results show that by improving the level of urbanization,we can effectively narrow the income gap between urban and rural areas,while socio-economic development,the improvement of education level,expansion of financial development scale and financial development efficiency all significantly expand the income gap between urban and rural areas.展开更多

Meanwhile the incomes of the rural residents can be boosted, which denotes the realization of a harmonious society where the achievements of China's reform and development are shared by each citizen. Moreover, the construction of NRCs facilitates the economization of land use and thus improves the overall living standard of the residents, while helping to cut the administrative cost and promote democracy at the primary level. This paper also points out various problems arising during the construction of NRCS in China: blindly following suit in accordance with the modes of the urban communities; lack of funds, which leads to the absence of the supporting mechanisms of NRCs; vague positioning and the ensuing shortage of impetus for continued development. Finally, the paper raises the corresponding measures and suggestions: first, based on reality, make overall planning and scientific arrangement; second, the government should play the dominant role while respecting the principal position of the rural residents and introducing the market mechanism; third, increase science and technology input and attach equal importance to economic and social benefits; fourth, broaden fund-raising channels while completing the supervision mechanism.展开更多

The main results show that:(i) The labor growth rate of urban-rural sectors must be greater than the time discount rate,or else there would be a vicious cycle of diminishing returns in the sectors;(ii) The accumulation rate of physical capital and human capital of urban-rural sectors,and the rate of technological progress,need to be greater than the corresponding depreciation rate plus the time discount rate,otherwise there would be a vicious cycle of diminishing returns in the sectors;(iii) The low accumulation rate in the rural sector,and the occurrence of labor outflow,human capital loss and lack of investment,will expand income gap between urban and rural areas,which is a reason for solidification of urban-rural dual economic structure.展开更多

Firstly,the paper carries out the descriptive statistical analysis about clothing consumption expenditures of urban and rural residents; secondly,based on questionnaires of 543 urban and rural residents in 16 provinces,this paper analyses structure and trend of urban and rural residents' clothing consumption. The results show that per capita clothing consumption expenditure of urban and rural residents present growth on the whole,but the gap between the two is gradually expanding; clothing consumption expenditure have differences in different regions; the differences of different income levels are also obvious; urban and rural residents' clothing consumption structure tends to be more diversified,cotton goods and chemical fiber goods is the main variety of clothing consumption,including down feather,cotton and chemical fiber is the main variety of coat,and cotton,chemical fiber and wool is the main variety of suit and knitwear; cotton goods,down goods and woolen goods will be the fiber goods that urban and rural residents buy more in the future; clothing consumption demand will pursue for band,comfort and personality; female residents will still be the main force of clothing consumption. Finally,the paper puts forward some recommendations on the basis of analysis results.展开更多

Industrial development in modern times has promoted the modernization of urban production in China. But the rural areas still maintain their traditional self-sufficient natural economy. After the Opium War, the process of modernization of city politics is promoted by more economic elements of capitalism and the formation of Chinese bourgeoisie. During the management of urban modernization, rural areas still adopt the traditional self-management mode. In the aspect of culture, city is the center of development, having large population, developed traffic, and prosperous culture. But the village is lack of information and its culture is relatively backward. In modern times, affected by the foreign capitalist, urban area has become the center of modern productivity. After separating from agriculture, handicraft industry has transferred into urban areas and the social division of labor in both urban and rural areas has shown great changes. Thus, a new pattern of "Urban Industry, Rural Agriculture" has formed.展开更多

Metals play a vital role as structural and functional components of proteins and enzymes in cell. The most important pathway of metals to transport into human is from soil to plant to human, so this study was carried out to measure the contents of heavy metals concentrations in plants leaves from their natural habitats of urban and rural area in Nasiriyah city, Iraq. The study was conducted to investigate the heavy metals content of four plant species of Eucalyptus, Olea, Zizphus and Conocarpus from urban (Nasiriyah city) and rural area (farms north of Nasiriyah). The concentration of heavy metals was tested, including the zinc, copper and lead. Heavy metals were detected using an atomic absorption spectrometer. The results showed that the highest concentration of heavy metals in Olea leaves and Eucalyptus leaves were found from the urban areas. Zn was the most dominant metal whereas Pb had the lowest concentration for all urban and rural area. Among the Eucalyptus, Olea, Zizphus and Conocarpus studied, showed higher heavy metals concentration (Zn, Cu and Pb) than rural area. The results indicated that the Zizphus and Conocarpus leaves of urban and rural area had the lowest heavy metals content compared with Eucalyptus and Olea. The results suggested that Eucalyptus and Olea leaves are good sources to treat the pollution of heavy metals. Our study provides a detailed examination of habitat location and plant species effects on potential of heavy metals in trees.展开更多

The methods of spatial statistical analysis, buffer analysis, Ripley's K function, kernel density analysis based on GIS(Geographic Information System) were used to analyze the characteristics of scale, spatial differentiation and spatial patterns of the rural settlements in Liangjiang New Area in Chongqing Municipality of China. The fractal dimension formula was also developed to reflect fractal feature of the rural settlements. The results show that, the scale of rural settlements in Liangjang New Area takes on distinct characteristics of spatial differentiation along with changes in elevation, gradient, location, geohazards distribution, and the like. The fractal characteristic of rural settlements has obvious regional variations subject to the 6 factors of location in the Liangjiang New Area. Overall, the worse the terrain conditions are, the larger the fractal dimension values become. The better the locationconditions, the larger the fractal dimension values are. The spatial pattern in the township scale presents three kinds of distribution as being aggregated, uniform and random. In contract, the spatial pattern in the plaque scale displays a banding distribution from a general view with several aggregation zones centering on each town center. From the results, we can see that the characteristics of rural settlements in urban fringe are more complicated. For such kind of rural settlements in special regions, in the rural land consolidation more attention should be paid to improve the rural living environments and public services, as well as to promote the harmonious relationship between the urban and rural areas.展开更多

However, green areas, including original fragments, can help to conserve native diversity, improving the functioning of these artificial systems in the long term. Urban areas can still provide habitats usable by wild birds, however the structural charac?teristics of the habitat formed by different types of green area differ, and therefore dissimilar bird diversities are to be expected. The object of this study was to characterise the α and β diversities of birds in different green areas and to analyse how diversity relates to ten variables that characterise the habitat.Methods: We studied the green areas in the city of Temuco, southern Chile(Park, Square and Median strips of main streets), evaluating the variables:(a) surface area,(b) vegetation,(c) estimated human impact as the proportions of vegetation and bare soil by area, and the vehicle traffic. The bird assemblage structures were characterised by α(intra?environment) diversity and β diversity(between environments) and the statistical analysis identified the environmen?tal variables related with the presence and abundance of birds. A statistical model was constructed to describe the contribution of the variables to bird diversity.Results: We found significant differences between the diversity of bird species in the three types of green area. The β showed medium to high similarity between the different study units. There was a negative correlation with bare soil areas; the correlations with vehicle flow, plant structure and tree and shrub cover were not significant, meaning that these variables did not explain the variation in the richness of bird species between the green areas. However the surface area did explain this variation presenting a positive potential relation. There was also a high correlation with the origin(native) of shrub species.Conclusions: The bird diversity varied significantly according to the type of urban green area. The environmental variables presenting significant correlations with bird diversity were: surface area, native species of shrub stratum, shrub cover, and bare soil area. The best multiple regression model showed that the three most important variables for bird diversity are the surface area of the green area, the cover of the shrub stratum and the presence of native shrub species.展开更多

The indirect negative effects are mediated through the infrastructure, and the combination of localized advantages and modern technical conditions could mitigate the negative impact of topography. Finally, we identify 742 counties as lagging regions in URI, which can be clustered into eight types. Our findings could facilitate policy designing for those countries striving for integrated and sustainable development of urban and rural areas.

文摘With rapid urbanization process, the pace of urban sprawl has been quickened and most metropolises have ex-perienced expansions in leaps and bounds in suburbanization, which has greatly changed the urban and rural spatial struc-ture of the metropolis fringe area. In this paper, Shuangliu County is taken as a case, since it is a typical fringe area of Chengdu Metropolis. Based on Landsat TM images of Chengdu City and Shuangliu County obtained in 1985, 2000 and 2004, characteristics of urban and rural spatial structure in Shuangliu County were analyzed, such as core-periphery spa-tial structure and some obvious integration trends. Then the influencing factors for the formation of urban and rural spatial structure were identified, including some natural, social, economic and political factors. According to the discussion of this paper, Shuangliu County is undergoing a key transition and reform period. Its formation of urban and rural spatial structure was affected not only by such common factors as the location, natural background, industrial transition, migra-tion, etc., but also by some unique factors such as city planning and policy guidance, which played an important role in accelerating its uneven spatial structure. The understanding of the role of the influencing factors would be useful for car-rying out spatial management and development planning of metropolis fringe area.

文摘The increasingly widening income gap between urban and rural areas is affected by many factors. Using the stepwise regression analysis,we find that urbanization level,socio-economic development,education level,financial development scale and financial development efficiency have the greatest impact on the income gap between urban and rural areas. By cointegration test,it is found that there is a long-term equilibrium relationship between these five variables and the income gap between urban and rural areas. We build the state-space model to research the dynamic impact of these factors on the income gap between urban and rural areas. The results show that by improving the level of urbanization,we can effectively narrow the income gap between urban and rural areas,while socio-economic development,the improvement of education level,expansion of financial development scale and financial development efficiency all significantly expand the income gap between urban and rural areas.
文摘On the basis of offering a definition of New Rural Communities (NRCs), the paper analyzes the values of New Rural Communities and argues that the construction of NRCs is able to contribute to the enhancement of the comprehensive agricultural production capability as well as the development of social productivity. Meanwhile the incomes of the rural residents can be boosted, which denotes the realization of a harmonious society where the achievements of China's reform and development are shared by each citizen. Moreover, the construction of NRCs facilitates the economization of land use and thus improves the overall living standard of the residents, while helping to cut the administrative cost and promote democracy at the primary level. This paper also points out various problems arising during the construction of NRCS in China: blindly following suit in accordance with the modes of the urban communities; lack of funds, which leads to the absence of the supporting mechanisms of NRCs; vague positioning and the ensuing shortage of impetus for continued development. Finally, the paper raises the corresponding measures and suggestions: first, based on reality, make overall planning and scientific arrangement; second, the government should play the dominant role while respecting the principal position of the rural residents and introducing the market mechanism; third, increase science and technology input and attach equal importance to economic and social benefits; fourth, broaden fund-raising channels while completing the supervision mechanism.

文摘Based on the characteristics of urban-rural dual economic structure in China,we build a dynamic endogenous urban-rural dual economic model closely linked to China's reality,and carry out mathematical economics analysis of optimized conditions for urban and rural sectors. The main results show that:(i) The labor growth rate of urban-rural sectors must be greater than the time discount rate,or else there would be a vicious cycle of diminishing returns in the sectors;(ii) The accumulation rate of physical capital and human capital of urban-rural sectors,and the rate of technological progress,need to be greater than the corresponding depreciation rate plus the time discount rate,otherwise there would be a vicious cycle of diminishing returns in the sectors;(iii) The low accumulation rate in the rural sector,and the occurrence of labor outflow,human capital loss and lack of investment,will expand income gap between urban and rural areas,which is a reason for solidification of urban-rural dual economic structure.

文摘In order to understand the historical origins of encircling the cities from the rural areas implemented by the Communist Party of China and the current dual structures of urban and rural development, urban-rural differences are analyzed from the four aspects of production mode, management mode, culture and social division of labor. Industrial development in modern times has promoted the modernization of urban production in China. But the rural areas still maintain their traditional self-sufficient natural economy. After the Opium War, the process of modernization of city politics is promoted by more economic elements of capitalism and the formation of Chinese bourgeoisie. During the management of urban modernization, rural areas still adopt the traditional self-management mode. In the aspect of culture, city is the center of development, having large population, developed traffic, and prosperous culture. But the village is lack of information and its culture is relatively backward. In modern times, affected by the foreign capitalist, urban area has become the center of modern productivity. After separating from agriculture, handicraft industry has transferred into urban areas and the social division of labor in both urban and rural areas has shown great changes. Thus, a new pattern of "Urban Industry, Rural Agriculture" has formed.
文摘Since heavy metals are the big concerns for the public health today. Metals play a vital role as structural and functional components of proteins and enzymes in cell. The most important pathway of metals to transport into human is from soil to plant to human, so this study was carried out to measure the contents of heavy metals concentrations in plants leaves from their natural habitats of urban and rural area in Nasiriyah city, Iraq. The study was conducted to investigate the heavy metals content of four plant species of Eucalyptus, Olea, Zizphus and Conocarpus from urban (Nasiriyah city) and rural area (farms north of Nasiriyah). The concentration of heavy metals was tested, including the zinc, copper and lead. Heavy metals were detected using an atomic absorption spectrometer. The results showed that the highest concentration of heavy metals in Olea leaves and Eucalyptus leaves were found from the urban areas. Zn was the most dominant metal whereas Pb had the lowest concentration for all urban and rural area. Among the Eucalyptus, Olea, Zizphus and Conocarpus studied, showed higher heavy metals concentration (Zn, Cu and Pb) than rural area. The results indicated that the Zizphus and Conocarpus leaves of urban and rural area had the lowest heavy metals content compared with Eucalyptus and Olea. The results suggested that Eucalyptus and Olea leaves are good sources to treat the pollution of heavy metals. Our study provides a detailed examination of habitat location and plant species effects on potential of heavy metals in trees.
文摘The rapid development of urbanization requires land management business should change the former single systematic pattern, and advance to integration of functions and data sharing. In order to meets the requirement, this paper presents a new thinking for land management pattern, and management tools of data center for integration of urban and rural areas. The tools were based on MapGIS, which have made the management of multi-subjects, multi-areas, multi-sources and multi-measurement data possible. The techniques of this system are designed accord with national related standard. Experimental result shows that the tools have obvious technical advantage in land resource business integration management.
文摘Nowadays, the development of quality education has always been attached great importance in China, of which the music education has been an important part. However, serious polarization of the urban and rural basic music education leads to all sorts of differences, thus seriously affecting the overall improvement of quality of all people. To find out the problems and the reasons of the backward in rural basic music education, this paper makes an analysis of the differences between urban and rural basic education development through a survey and a study of basic situation in music education of urban and rural elementary school in Gaocheng, Hebei province, and then puts forward thinkings and suggestions about narrowing the urban-rural music education gap on the basis of the analysis of internal and extemal problems.
文摘Taking northern Jiangsu area as an example,economic disparity between urban and rural areas is described according to the data in 2000-2009 Jiangsu Statistical Yearbook.Result shows that there are significant differences in the rural and urban economic development in less developed areas,which are mainly reflected in the differences in per capita income,living standard,and Engel coefficient.Reasons for urban and rural economic disparity in less developed areas are analyzed.The asymmetry and immobility of rural and urban resources have objectively caused the income gap between urban and rural residents;urban industrial development,which is faster than agricultural development,has widened the income gap between urban and rural residents;and the differences in comparative labor productivity in rural and urban areas have enlarged their income gap.Countermeasures to minimize the urban and rural economic development gap are put forward,such as deepening the reform,realizing the free flow of economic resources between urban and rural areas,developing rural areas through urban development,exerting the function of urban areas in the coordinated development of urban and rural areas,paying attention to the agriculture and rural areas,and improving the comparative labor productivity of agriculture.

文摘The objective of this paper is to analyze land use characteristics of rural settlements in urban fringe so as to provide references for optimizing the regional distribution of rural settlements, consolidating rural settlements, and coordinating urban-rural integrated development. The methods of spatial statistical analysis, buffer analysis, Ripley's K function, kernel density analysis based on GIS(Geographic Information System) were used to analyze the characteristics of scale, spatial differentiation and spatial patterns of the rural settlements in Liangjiang New Area in Chongqing Municipality of China. The fractal dimension formula was also developed to reflect fractal feature of the rural settlements. The results show that, the scale of rural settlements in Liangjang New Area takes on distinct characteristics of spatial differentiation along with changes in elevation, gradient, location, geohazards distribution, and the like. The fractal characteristic of rural settlements has obvious regional variations subject to the 6 factors of location in the Liangjiang New Area. Overall, the worse the terrain conditions are, the larger the fractal dimension values become. The better the locationconditions, the larger the fractal dimension values are. The spatial pattern in the township scale presents three kinds of distribution as being aggregated, uniform and random. In contract, the spatial pattern in the plaque scale displays a banding distribution from a general view with several aggregation zones centering on each town center. From the results, we can see that the characteristics of rural settlements in urban fringe are more complicated. For such kind of rural settlements in special regions, in the rural land consolidation more attention should be paid to improve the rural living environments and public services, as well as to promote the harmonious relationship between the urban and rural areas.
文摘Background: Urbanisation is a dominant geographical trend and an important component of global change, with unprecedented implications for socio?economic, cultural and environmental characteristics. However, green areas, including original fragments, can help to conserve native diversity, improving the functioning of these artificial systems in the long term. Urban areas can still provide habitats usable by wild birds, however the structural charac?teristics of the habitat formed by different types of green area differ, and therefore dissimilar bird diversities are to be expected. The object of this study was to characterise the α and β diversities of birds in different green areas and to analyse how diversity relates to ten variables that characterise the habitat.Methods: We studied the green areas in the city of Temuco, southern Chile(Park, Square and Median strips of main streets), evaluating the variables:(a) surface area,(b) vegetation,(c) estimated human impact as the proportions of vegetation and bare soil by area, and the vehicle traffic. The bird assemblage structures were characterised by α(intra?environment) diversity and β diversity(between environments) and the statistical analysis identified the environmen?tal variables related with the presence and abundance of birds. A statistical model was constructed to describe the contribution of the variables to bird diversity.Results: We found significant differences between the diversity of bird species in the three types of green area. The β showed medium to high similarity between the different study units. There was a negative correlation with bare soil areas; the correlations with vehicle flow, plant structure and tree and shrub cover were not significant, meaning that these variables did not explain the variation in the richness of bird species between the green areas. However the surface area did explain this variation presenting a positive potential relation. There was also a high correlation with the origin(native) of shrub species.Conclusions: The bird diversity varied significantly according to the type of urban green area. The environmental variables presenting significant correlations with bird diversity were: surface area, native species of shrub stratum, shrub cover, and bare soil area. The best multiple regression model showed that the three most important variables for bird diversity are the surface area of the green area, the cover of the shrub stratum and the presence of native shrub species.
