Rural areas are crucial for a country’s sustainable economy.New strategies are needed to develop rural areas to improve the well-being of rural population and generate new job opportunities.This is especially important in countries where agricultural production accounts for a significant share of the gross product,such as Russia.In this study,we identified the key indicators of satisfaction and differences between rural and urban citizens based on their social,economic,and environmental backgrounds,and determined whether there are well-being disparities between rural and urban areas in the Stavropol Territory,Russia.We collected primary data through a survey based on the European Social Survey framework to investigate the potential differences between rural and urban areas.By computing the regional well-being index using principal component analysis,we found that there was no statistically significant difference in well-being between rural and urban areas.Results of key indicators showed that rural residents felt psychologically more comfortable and safer,assessed their family relationships better,and adhered more to traditions and customs.However,urban residents showed better economic and social conditions(e.g.,infrastructures,medical care,education,and Internet access).The results of this study imply that we can better understand the local needs,advantages,and unique qualities,thereby gaining insight into the effectiveness of government programs.Policy-makers and local authorities can consider targeted interventions based on the findings of this study and strive to enhance the well-being of both urban and rural residents. 展开更多

Transportation accessibility has been treated as an important means of reducing the urban-rural income disparity.However,only a few studies have examined the effects of different types of transportation accessibility on urban-rural income disparity and their spatial heterogeneity.Based on data from 285 prefecture-level(and above)Chinese cities in 2000,2005,2010,2015,and 2020,this study uses spatial econometric models to examine how highway accessibility and railway accessibility influence the urban-rural income disparity and to identify their spatial heterogeneity.The result reveals that highway accessibility and railway accessibility have‘coreperiphery’ring-like circle structures.The urban-rural income disparity exhibits strong spatial clustering effects.Both highway accessibility and railway accessibility are negatively associated with urban-rural income disparity,and the former having a greater effect size.Moreover,there is a substitution effect between highway accessibility and railway accessibility in the whole sample.Furthermore,these associations differ in geographic regions.In the central region,highway accessibility is more important in reducing the urban-rural income disparity,but its effect is weakened with the increase of railway accessibility.In the western region,railway accessibility has a larger effect on narrowing the urban-rural income disparity,and this effect is strengthened by the increase of highway accessibility.We conclude that improving transportation accessibility is conducive to reducing the urban-rural income disparity but its effect is spatial heterogenetic.Highways and railways should be developed in a coordinated manner to promote an integrated transport network system. 展开更多

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. 展开更多

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. 展开更多

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. 展开更多

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. 展开更多

Urbanization is one of the driving forces for the land use change in type and structure, and its prominent effect is to convert rural land to urban land. This paper takes Shan-dong Province as an example to analyze the current situation of the mutual conversion between the urban and rural areas from the aspects of the structure of land use, the decreasing tendency of the cultivated land, the changes of land use in urban and rural residential areas. It points out that cultivated land is converted to residential area land, industrial and/or mining area land. The relationship between the urban area land and the cultivated land is more direct; meanwhile, the changes of rural residential area lag behind obviously. The decrease of the cultivated land and the decline of soil quality will be the two difficult problems in the process of urbanization. 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 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. 展开更多

With the rapid development of urban agglomerations in northwest arid and semiarid regions of China, the scope of the urban heat island(UHI) effect has gradually expanded and gradually connected, and has formed a regional heat island(RHI) with a larger range of impact to the regional environment. However, there are few studies on the heat island effect of urban agglomerations in arid and semiarid regions, so this paper selects the urban agglomeration of Hohhot, Baotou and Ordos(HBO) of Inner Mongolia, China as the study area. Based on the 8-day composite Moderate-resolution Imaging Spectroradiometer(MODIS) surface temperature data(156scenes in all) and land use maps for 2005, 2010, and 2015, we analyze the spatiotemporal distributions of regional heat(cool) islands(RH(C)I) and the responses of surface temperatures to land-use changes in the diurnal and interannual surface cities. The results showed that: 1) from 2005 to 2015, urban areas showed the cold island effect during the day, with the area of the cold island showing a shrinking feature;at night, they showed the heat island effect, with the area of the heat island showing a first decrease and then an increase.2) From 2005 to 2015, the land development(unutilized land to building land) brings the greatest temperature increase(ΔT = 1.36°C)during the day, while the greatest temperature change at night corresponds to the conversion of cultivated land to building land(ΔT =0.78°C) exhibited the largest changes at night. From 2010 to 2015, the land development(grassland to building land) bring the greatest temperature increase(ΔT = 0.85°C) during the day, while the great temperature change at night corresponds to the conversion of water areas to building land(ΔT = 1.38°C) exhibited the largest changes at night. Exploring the spatial and temporal evolution of surface urban heat(cool) islands in urban agglomerations in arid and semiarid regions will help to understand the urbanization characteristics of urban agglomerations and provide a reference for the formulation of policies for the coordinated and healthy development of the region and co-governance of regional environmental problems. 展开更多

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. 展开更多

Understanding the effects of land use changes on the spatiotemporal variation of soil organic carbon (SOC) can provide guidance for low carbon and sustainable agriculture. In this paper, based on the large-scale datasets of soil surveys in 1982 and 2009 for Pinggu District -- an urban-rural ecotone of Beijing, China, the effects of land use and land use changes on both temporal variation and spatial variation of SOC were analyzed. Results showed that from 1982 to 2009 in Pinggu District, the following land use change mainly occurred: Grain cropland converted to orchard or vegetable land, and grassland converted to forestland. The SOC content decreased in region where the land use type changed to grain cropland (e.g., vegetable land to grain cropland decreased by 0.7 g kg-1; orchard to grain cropland decreased by 0.2 g kg-l). In contrast, the SOC content increased in region where the land use type changed to either orchard (excluding forestland) or forestland (e.g., grain cropland to orchard and forestland increased by 2.7 and 2.4 g kg-1, respectively; grassland to orchard and forestland increased by 4.8 and 4.9 g kg-1, respectively). The organic carbon accumulation capacity per unit mass of the soil increased in the following order: grain cropland soil〈vegetable land/grassland soil〈orchard soil〈forestland soil. Therefore, to both secure supply of agricultural products and develop low carbon agriculture in a modern city, orchard has proven to be a good choice for land using. 展开更多
