After the rainstorm, the phenomenon of “sea views” is common. The direct reason is that the urban drainage system and the ground drainage system cannot afford the large flow of water in a short period of time, but the most fundamental reason is that the artificial construction environment changes the water storage and drainage function of the ground under the natural state. “Sponge city construction” came into being. This paper mainly analyzes and studies the sponge city construction in Pingxiang City, Jiangxi Province, and uses the method of field investigation and literature data to clarify the ideas of the sponge city construction in Pingxiang City and summarize the successful experience, which can provide a reference for the subsequent “sponge city development” ideas.展开更多

Institution based cross-sectional study was carried out. A total of 337 women of reproductive age group with disabilities were included in the study with simple random sampling. Data were collected through face-to-face interview, coded, cleaned and entered by Epi info 2002 and analyzed with SPSS version 16 computer software. Logistic regression was used to assess possible associations. The magnitude of unmet need for family planning among women with disabilities was 24.3%. Women with disabilities in the age group of 25-29 had 80% less likely to have unmet need than women above 35 years old. Women with disability who have no education were 11 times more likely to have unmet need than those who have secondary education. Women who desire to have more than 3 children have more likely to have unmet need than those who need to have 1-2 children. Unmet need for family planning among women with disabilities was high in Bahir Dar town. Age, Educational status and desired number of children were found to have statistically significant association with unmet need for family planning. Hence, it is important to encourage people with disabilities to attained formal education and the associations should provide short term trainings in accordance with their age group.展开更多

Meanwhile, based on the target data of overal land use plan, the level of land comprehensive carrying capacity was predicted at the end of the plan period (2020) .The results showed that land comprehensive carrying capacity had a significant growth in Lin ’an from 2005 to 2012, and the development trend was basical y sustainable. The sub-systems also had been greatly improved, in which the constant improvement of ec-ological environment carrying capacity made the largest contribution to the constant raising of land comprehensive carrying capacity. The degree of coordination between the systems was poor, in which eco-environment carrying capacity had the maxi-mum growth, far more than the social and economic carrying capacities. According to the land comprehensive carrying capacity in 2020, utilization of land resources in Lin'an city can achieve sustainable development in general. Final y, proposals of im-proving comprehensive carrying capacity were put forward in terms of the enhance-ment of eco-environment protection, accelerating economic development and policy guidance.展开更多

Analysis and assessment of vulnerability provide a new basis for urban planning. This study constructed a quantitative index system for assessing vulnerability, based on the city′s sensitivity and emergency response capacity. City size, density, and spatial form influence a city′s sensitivity to crises and risks, to which vulnerability is positively related. Levels of socio-economic development, infrastructures, and emergency management contribute to a city′s emergency response capacity, with which vulnerability is inversely associated. Vulnerability of 19 large Chinese cities was assessed. Harbin and Shenzhen demonstrated the highest and lowest vulnerability among 19 cities, while Beijing, Shanghai and Guangzhou ranked the 5th, the 9th and the 12th. Spatially, northern cities tended to be more vulnerable than southern cities. And the differences in vulnerability among cities were explored based on cities′ physical geography conditions, level of socioeconomic development, infrastructures, regional status, history of disaster, history of urban planning and development, government policies, etc.展开更多

In the pre-reform era, the city was defined as a productive space under the system of urban-rural segregation established for securing rapid industrialization. Urban planning was thus only concerned with the development of urban areas. In the 1980 s and 1990 s after the reform, institutional change and economic transformation mobilized the urban-rural linkages. The development of suburban areas was then considered by urban planning, but this consideration was a passive response to urban problems such as population explosion and water resources protection. Since the new millennium, the agenda for sustainable development and problems of uneven urban-rural development have called for the development of urban-rural integration. In this context, the city is conceptualized as a complex of mountain, city, river, farmland and sea, reconstructing the ideology of urban-rural division in defining urban development. Urban planning has therefore sought in an active way to develop a sustainable city embracing rural and natural elements, and to balance economic growth and environmental protection. It is argued that developing the concept of city as a complex of urban and rural elements contributes to the urban planning for sustainable urban development, while this conceptualization relies on the recognition of the integrated urban-rural relationship.展开更多

Sponge city technology is widely used as the critical approaches in natural rainwater management and it is one of the best techniques to adapt climate change events in modern cities. In the paper, we firstly reviewed background information of sponge city construction and the development, key technologies, and economic benefit analysis of stormwater management in foreign countries. Then, we analyzed the technology gap between China and developed countries in two aspects (planning design method and Low Impact Development (LID) project design). Then, we pointed out the main obstacles in sponge city technology transfer and proposed to improve the basic data sharing system and strengthen the economic return system. On the basis of sponge city planning theory and sponge city technologies, taking Shenzhen as an example, we analyzed the ideas and plans of sponge city construction in rainy areas and completed the assessment of current climate technology demands in Chinese sponge city. The study provides the basis for the improvements in sponge city construction and adaptation to climate change.展开更多

This study from different perspectives designed the alternatives for Changchun's county-level road and urban road system planning, and used the method of System Dynamics to simulate, optimize and analyze those alternatives. Thereafter, some methods including the correlation function method were used to comprehensively assess and rank those alternatives for recommending two best alternatives with the consideration to the indicators, such as the total emission amount of CO, the total emission amount of nitrogen oxides, the noise value, the road construction cost, the fossil oil consumption and the traffic capacity. The result showed that the study would provide substantial supports for decision-makers to make more scientific decisions and promote the sustainable urban traffic in Changchun City.
文摘Characteristic urban construction has already become a trend of modern social development,in this context,components of characteristic urban green spaces,and ways of demonstrating features of urban green space system were analyzed.Shuangcheng City in Heilongjiang Province was taken for example to analyze planning objectives and principles of characteristic urban green space system.Moreover,the green space layout of "A Hundred Years Old Castle,A Hundred of Enterprises and A Hundred of Gardens" was introduced.It was proposed that green space system planning suited to the development features and ecological conditions of the city should be developed from the perspective of greater regional environment,historical and cultural deposits,urban development pattern and lifestyle of the locals,so as to create urban green space system with regional features.

文摘By focusing on Guangzhou, this paper examines how different concepts of city in terms of urban-rural relationships are shaped in transforming China since 1949, and explores how they influence the way in which urban planning are practiced. In the pre-reform era, the city was defined as a productive space under the system of urban-rural segregation established for securing rapid industrialization. Urban planning was thus only concerned with the development of urban areas. In the 1980 s and 1990 s after the reform, institutional change and economic transformation mobilized the urban-rural linkages. The development of suburban areas was then considered by urban planning, but this consideration was a passive response to urban problems such as population explosion and water resources protection. Since the new millennium, the agenda for sustainable development and problems of uneven urban-rural development have called for the development of urban-rural integration. In this context, the city is conceptualized as a complex of mountain, city, river, farmland and sea, reconstructing the ideology of urban-rural division in defining urban development. Urban planning has therefore sought in an active way to develop a sustainable city embracing rural and natural elements, and to balance economic growth and environmental protection. It is argued that developing the concept of city as a complex of urban and rural elements contributes to the urban planning for sustainable urban development, while this conceptualization relies on the recognition of the integrated urban-rural relationship.
文摘Sponge city is a development pattern used to realize natural accumulation, natural infiltration and natural purification of rainwater through urban planning and construction management. Sponge city technology is widely used as the critical approaches in natural rainwater management and it is one of the best techniques to adapt climate change events in modern cities. In the paper, we firstly reviewed background information of sponge city construction and the development, key technologies, and economic benefit analysis of stormwater management in foreign countries. Then, we analyzed the technology gap between China and developed countries in two aspects (planning design method and Low Impact Development (LID) project design). Then, we pointed out the main obstacles in sponge city technology transfer and proposed to improve the basic data sharing system and strengthen the economic return system. On the basis of sponge city planning theory and sponge city technologies, taking Shenzhen as an example, we analyzed the ideas and plans of sponge city construction in rainy areas and completed the assessment of current climate technology demands in Chinese sponge city. The study provides the basis for the improvements in sponge city construction and adaptation to climate change.

文摘This paper focuses on climate comfort degree evaluated from relationships between spatial characteristics and behaviors of a winter city.It is demonstrated that the influences of climatic factors on human comfort are remarkably different for different spatial characteristics and functions of the sites.An evaluation method of climatic comfort is propsed,in which attaining comfort is an adaptation process,and the dynamic changes in the process are according to the user’s subjective tendency to the variations of the spatial characteristics and functions of the space.The evaluation criteria are based on both physical and psychological hierarchy needs of a person,which include the spatial form for microclimatic conditions as well as the spatial social-economic characteristics of a site.To improve the local environment of a winter city by planning measurements,the Harbin Central Pedestrian Street is taken as an example in the application of the evaluation method,and different planning optimizing strategies are proposed accordingly.The results show that the pattern of climate comfort is characterized by reflecting the socialeconomic value and individual behavior characteristics.
