| At present, China is in the process of rapid urbanization and industrialization development stage, excessive pursuit of economic growth make contradictions between the city development and environmental protect intensified, a series of urban issues highlight, such as imbalance of regional spatial structure, social development and so on, with the putting forward of scientific development view, status of traditional space planning system from the guiding ideology to planning means are not sufficient to meet the requirements of sustainable development. In this context, this paper hope starting from the Nature of urban ecosystems, ecology theory will be integrated into the space planning system in different levels of planning content, in order to achieve the economic, social and ecological coordinated development.The first part is an introduction, it presents the background of this study and the basis of this topic, summarizes the research status at home and abroad, provides a brief argument presented in this study and determines the purpose, content, meaning, method and framework of this study. The second part summarizes the theory of ecology, as the theoretical basis for later study. The third part of the main part of this study, through the objective analysis on space planning system status deficiencies, combined with the second part of the theoretical basis, further clearly put this article argument that the concept of ecologization of space planning system, and constructing theory and operating system of different levels of ecologization of space planning, at the same time, using JiaYuGuan city land use planning practical cases to realize the combination of theory with practice. The paper concludes that the fourth part of the article, which summarizes the conclusions of this paper and deficiencies during the course of the research.This paper based on the present situation of space planning system and the objective analysis of sustainable development needs, take realizing the transformation to the ecologization of space planning as the key. Meanwhile, it puts forward the whole concept of ecologization of space planning system, aimed at different levels of different functions, constructs ecological theory osmosis and use system during different levels space planning, finally Strives on providing a reference to the urban sustainable development and the improvement of the ecological environment. |
