A Primary Study On The Integrated Construction Of Urban Green Space System Based On The Ecological Conception

Along with the Chinese urbanization advancement development, the city ecological construction has become the inevitable trend of the urban development. How in the city ecological construction maintains the earth life system's integrity and health, completes harmony of the humanity and the nature, harmony of the development and the environment, has become the key of the urban sustainable development and the important proposition of constructing harmonious social. In order to discuss this topic, the paper take the conception of "City Ecology" as the instruction, thought "City Ecology" must contain two stratification planes: the material category's ecology and the spiritual category's ecology, then rises the City Green System to the region geography ancJ the spiritual culture altitude, proposed the Urban Green Space System's concept, thought the Urban Green Space System's ecological protection and ecological construction are one of the important ways that organizes city's overhead landscape space and solves city's ecological question, also is the urgent need to implement the urban sustainable developmental strategy.Based on the above understanding and the idea, the paper first makes analysis to the Urban Green Space System from the discipline and the concept, definite and limit research scope of the paper. Afterwards, the paper summarizes idea inheritance of the domestic and the foreign city green space construction, had clearly recognized the City Ecology's essential connotation and characteristic. From material, spiritual, cultural three theories stratification plane, the paper constructs the Urban Green Space System theory's stratification plane structure, and union the understanding of planning philosophy idea, proposes the rationality and the non-rational thought of the Urban Green Space System planning.Next, in the foundation of theory research, the paper proposes the Urban Green Space System's spatial structure: Macroscopic (Urban Green Space System), medium view (City Green System) and microscopic (City Greenland) three spatial levels. And in the understanding of the Urban Green Space System's special characteristic function, the paper proposed its function should be the bonding of ecological, economical, social, and cultural function. Based on the recognition of relations among Urban Green Space System , City Green System and City Greenland, the understanding of the Urban Green Space System's ecological characteristic, the paper has carried on the preliminary discussion of the Urban Green Space System's ecological construction.Take the City Green System as the research object, which is the medium view stratification plane of the Urban Green Space System. Paper from the City Green System's special characteristic function, the City Greenland's reasonable quantity, the City Green System's spatial structure, the City Greenland's shape control, and the City Greenland's ecological function benefit five aspects discussed the ways of the City Green System's ecological construction.Selects method which the theory research and the case research unifies, in view of the overseas Moscow City Green System planning and the domestic Nationallevel garden cities----Beijing, Shenzhen, Zhuhai, and Foshan City Green Systemplanning, the paper has carried on analysis and appraisal for those, Summarizes thought tendency and experience of the City Green System planning.Finally, unifies the above research results, take the Hefei City Green System planning research as an actual proof object. the paper embarks from the Hefei City Green System's development evolution and the present situation analysis, and excavates its superiority and potential. Through the conjugate relation's discussion of the City Green System and the urban form structure, unifies the evolution rule of the Hefei city form structure, the paper has initially devised Hefei City Green System's mountain-water landscape pattern which take the mountain scenery, the water scenery, the green scenery as the leading. Based on the Urban Green Space System and the City Green System two levels, the planning idea, the ecological strategy, the ecological construction three aspects, the paper carried on the ecological construction to the Hefei City Green System, and put forward the planning implementation policy proposal.
