This paper uses LID concept to construct sponge city in the old urban area of Kunming,to reduce the total runoff and promote the utilization of rainfall and flood resources so as to rebuild,upgrade and optimize the regional environment and provide some reference for the regional construction of small-scale sponge city.展开更多
文摘Based on investigating the present greening situation of 18 overpasses in the urban area of Kunming City,4 typical plant furnishing modes for overpass were concluded,that is,Type Ⅰ,which was the multi-layered plant disposition pattern composed of all arbor,shrub and herbaceous plant species;TypeⅡ,which was mainly composed of shrub and herbaceous species with a 2-layered structure;Type Ⅲ was the turf grass pattern with sparsely disposed trees;Type Ⅳ,which was the simple groundcover greening pattern.1 or 2 typical overpasses from each type were sampled separately for evaluating the landscape effects of the typical green space around each type of overpass by adopting AHP model,and the results showed that the evaluated landscape effect of Type Ⅰ was 'good',that of Type Ⅱ was 'moderate',that of Type Ⅲ was 'moderate to good',and that of Type Ⅳ was 'poor'.

文摘Sponge city construction,as an important measure of ecological construction in China,can effectively solve a series of problems such as large annual runoff,serious non-point source pollution,regional water shortage,low utilization rate of rain and flood resources,unsustainable ecological benefits of water landscape and poor landscape functions in urbanization construction. This paper uses LID concept to construct sponge city in the old urban area of Kunming,to reduce the total runoff and promote the utilization of rainfall and flood resources so as to rebuild,upgrade and optimize the regional environment and provide some reference for the regional construction of small-scale sponge city.
