Optimization Design Research Based On Sponge City And GIS Analysis Method Of Street Public Green Space In Built-up Urban Area

Runoff in urban built-up area is easy to result in some water environment problems,the streets in where undertake the vital function of runoff transportation,and take on a series of landscape functions.Advanced technology and theories such as Water Sensitive Urban Design,Green Infrastructure,Green Street and Low Impact Development in the foreign countries,which have integrated the stormwater utilization system and the landscape multifunction theories successfully.This article based on the theory of Green Street,by means of Landscape Multifunction theory,and various urban street and building classification systems,studies the suitability evaluation strategy of the sponge city applies to the street space's green area in the urban built-up area in China.A multifunction landscape indicator system has been explored in this article.Which can generate Land Use SuitabilityAnalysis Layout in ArcGIS software.Based on the result can verify the rationally of design project in Tengfei Avenue in Chengdu,Sichuan.In the research can draw these conclusions:(1)Based on the ArcGIS,which can analysis the suitability of current situation of micro scale streetscape.The result is more reasonable and effective than traditional landscape design method.(2)The GIS suitability indicator system is explored based on the theory of Multifunction Landscape,Green Infrastructure and Green Street,which integrate the AHP method and generate the weight coefficient could apply in the suitability assessment in other green area among different kinds of streets in built-up urban area...
