Eco-Efficient Study Of The Spatial Structure For Green Space System In Urban Development Area

Urbanization is the result of the development of human science, culture and economy. As the promoting of urbanization, the urban ecological environment is deteriorating. The urban green space system, anchored with great hope in improving urban ecological environment, has a rising status in the urban construction all over the world.Over the past30years since the introduction of reform and opening to the outside world, especially in the last decade, urbanization in China has a significantly improvement.Due to the former urbanization level in China is relatively low; there is a huge demand of city expansion. As the urbanized area is growing explosively, the urban ecological environment is degenerating rapidly. At the mean time, because of the restriction of both physical geography and social economy, it costs extraordinary high to increase greening land in urbanized area. In contrast, to increase greening land in urban development area costs relatively low. In addition to this, it is easier to build up green space systemly.Eco-efficient of green space system is closely related to its spatial structure.However. the present planning decisions are majorly focus on the qualitative aspect. The quantitative research is scarce.These factors cause the planning decisions lack persuasion in the urban Planning System and it is restricted by other specialty planning.This paper is to research, under Chinese present urban planning administration system, the impact on the Eco-efficient from the spatial structure within green space system by establishing spatial model and to discuss and to analyze the causes.To provide the urban green space system planning decisions with technical support by quantitatively research and analysis, the paper contains the following three parts:The first part, focus on background research, includes two chapters. It is the brief description of the background, significance, purpose, method, relative concept and the present situation of the research home and abroad.The second part includes two chapters, is to discuss the parameter settings of spatial structure and the evaluation method of Eco-efficient by researching literatures, analyzing cases and summarizing the urban construction ideal.The last part contains the fifth chapter to the seventh chapter. Base on the research results of second part, it draws the spatial structure model of green space system which set the parameter and proofs the rationality of the spatial structure. Then it discusses the influencing factors of green space system Eco-efficient and the relation between them by evaluating the Eco-efficient of the green space system spatial structure. On the basis of all the analysis, the paper recommends proposals to the construction of green urban space system.
