Study On Urban Green Space System Planning Based On "LID"

With the implementation of urban development strategy,the Chinese urban agglomeration has roused rapidly recently years.However,kinds of urban water problem such as flood,water logging,water pollution,and water shortage occurred at the time.Traditional theory of greenbelt plan is circumscribed,which always neglects the function of marine system about risk control and security.Construction of LID is more significant in solving the integrated city problem at macro level and mesoscale.In practical terms,the urban green LID system makes greenbelt and urban aquatic ecosystem as an organic whole.Based on the experience of green space system planning and LID construction,this paper puts forward the core idea and planning method of urban green space system planning under the guidance of LID concept.Taking the county town of Anhui province green space system planning as an example,explain the specific method and the core idea application.Focus on the following research work:(1)Theoretical researchI summarize the connotation of “LID”,and put forward the theoretical research on combining LID with urban greenbelt planning.Consequently i realize that LID and urban greenbelt planning promote and complement each other,although to some extent they are different.This paper says a theory of urban greenbelt planning,which is mainly about ecological infrastructure and safe pattern of water ecological.Discussing of greenbelt planning step by step afford a theoretical basis for this essay.(2)Innovative ideasIn this paper,i trend to specialize the way of greenbelt planning which bases on the theory of LID and combines with landscape knowledge.The specific solution is concluded in three aspects,macro level,middle view,and micro-block.It covers the source,process,and the ending.The theory mentions the formation of water security,the establishment of LID,and the selection of LID facilities.This paper also promotes the construction of conditional evaluation system and the greenbelt planning oriented to water ecological infrastructure.(3)Theory and project practiceTaking the greenbelt planning in the county of Anhui province as an example,i practice the theory into specific project.My expectation is that the theory in this paper will be useful and meaningful to the construction of LID and greenbelt planning someday.
