Abstract: Land is limited and renewable resource, also the renewability of many composites of land productivity is limited. A large acreage of land is occupied temporarily or permanently by road construction projects. In the later stage of road construction projects, land reclamation is a key issue for land resource protection. Basing on investigation and study, this paper is to conclude the land reclamation methodology and key technologies, and provide technical reference.

Abstract: Green belt is a useful method to management growth of a city. It aims to prevent cities from growth irregularly, protect open spaces, provide recreational and educational space and prevent historic towns from urbanization. Green belt policy has been used to deal with the environment problems and nature conservation issues. Scotland has a long history of setting out green belt policy and putting it into practice successfully. This paper focus on comparing the green belt policy differences between Scotland and China based on history and planning system angles. The results of this study indicate that there are several problems during the process of setting and carrying out green belt policy in China. And it suggests that the green belt policy will be much more efficient by reducing planning procedures and increasing participation of local public.

Abstract: In recent years, the issue of migrant workers as well as the protection of farmland has been attracting wide attention from society. And it is related to another more serious problem——at least 30% of the arable land is abandoned prevalently in the Midwest and it is spreading, which has a direct impact on the food security of the country. Because it is too complicated to solve, and there is no way to overcome the phenomenon. The author takes abandoned farmlands in Huofeng village Gaoping district, Nanchong city, Sichuan Province for example, and makes generalization and summary to the farmlands abandoned phenomenon as well as its reason through the fieldwork investigation. And meanwhile, make some suggestions about solving the problem of rural areas’ abandoned farmlands in the hilly areas and hope to draw universal attention of the whole society on the phenomenon of abandoned farmlands in rural areas.

Abstract: In recent years, due to the differences between natural environment and the human way of life, under the pressure of environment and development, there presented varying degrees of frangibility in different areas. Take the north mountain of Hebei Province as an example to make spatio-temporal analysis, which can provide basis for sustainable development of economic, society and environment. Research results showed that: from the perspective of time series, the overall situation of ecological environment was improved, and the average ecological frangibility index declined by 0.19% from 1987 to 2000, and it declined by 0.77% from 2000 to 2008. From the perspective of space series, the overall state was improved.

Abstract: Under the background of current Chinese rapid urbanization,the vernacular landscape of small towns is faced with severe challenges.We clearly define the concept of the vernacular landscape of small towns ,analyze its characteristics and constituent elements. Four practical dilemmas are deeply analyzed, which are the constructive destruction of the rapid urbanization, the convergence of planning and design and the loss of local characteristics,despising the value of the vernacular landscape of small towns,the distortion and rupture of the vernacular landscape.Finally the countermeasures for protection and development of the vernacular landscape of small towns come up,which is respectively correctly cognition of small towns and their vernacular landscape value, adding special contents about landscape protection of small towns in the planning and design,building up ideas about overall protection and organic update.

Abstract: With the building of Central Plains Economic Zone written on the national development strategy, a new opportunity is approaching to the development of Jiaozuo. This paper firstly expounds the overview of Jiaozuo coal mining area and the connotation of Central China Economic Zone under the Angle of Central China Economic Zone, Combines the Research of Land Reclamation and Ecological Reconstruction with Related Practice in Jiaozuo coal mining area, it goes deeply into the analysis on the research according to the positioning and requirements of Jiaozuo in the Central China Economic Zone. Study on the direction of Land Reclamation and Ecological Reconstruction in Jiaozuo coal mining area under the Angle of Central China Economic Zone, aiming to provide some theoretical reference on the Research of Mine land remediation and utilization for Resource-exhausted Cities in the time of Development Strategic Transformation.

Abstract: Analyzed the water environment situation of Chinese city, discussed the position and function of the water in the construction of ecological city, used methods of typical cases, revealed the severe problems of city water ecological environment, put forward the optimization strategy of water environment in the process of ecological city construction.

Abstract: The reflection on the region, environment and ecology of Jiaxing is the subject which the author pays attention to chronically. In this article, on the base of regions south of Yangtze River, from the standpoint of environment and ecology, the author analyse Jiaxing roundly. The writer combines Jiaxings unique characteristics together, namely the water as the source, the green as the goal and the culture as the background, to show the ecological environment and ecological planning of this city, so as to endow Jiaxing with more ability of scientific development and make it clear and frofound for public to understand the livable ecological planning of Jiaxing.

Abstract: Urban ecosystem is a multi-level giant system continuous developing and consist of nature, economy, sociaty and other elements. By adopting the analytic hierarchy process (ahp) this paper established the Changsha urban ecosystem sustainable development indicator system and weight, and used the improved TOPSIS model to evaluate Changsha urban ecosystem development ability.

Abstract: Following strategies of Coastal Open Go West and Reviving Northeastern Old Industrial Base the state put forward the strategy of Rising of Central China in order to promote its rapid development. Urban agglomeration in Central China is becoming academic focus with unprecedented development momentum. It applies multidisciplinary theory of human geography, regional economics, etc. and takes urban agglomeration of Hunan, Henan and Hubei provinces for example to empirical analysis. Firstly, analyzing the historical evolution, urbanization space development and patterns then comes to spatial association of urban and rural through comparison, Finally, showing the development characteristics of urban agglomeration in Central China and putting forward urbanization suggestion.
