Abstract

Under the concept of new urbanization, China’s urban construction path is constantly adjusted and optimized, but the development and ecological protection has been unable to coordinate. The natural environment of mountain city is good, but the ecological environment carrying capacity is relatively weak and the resilience is not enough to resist the change of complex environment. This study considers the concept of sponge city as an opportunity, and based on analysing the characteristics of mountain city, elaborated the core construction content of sponge mountain city, pointed out the mountain city should assess timely the geological hazards, actively protect the natural green sponge bodies, gradually optimize the layout of sponge bodies, reasonably divide the urban drainage area and analysis the flood submerged area along the water areas. Then this study uses the GIS technical tools of spatial analysis and others, and took Wugang city of Henan Province as the research object, firstly analysis the geological disaster prone areas of Wugang City, especially in the West and southeast mountain areas, and then divided the catchment area, which was divided into three districts, made the Tieshan Avenue as boundary for the north and south two areas, the three area was the northern industrial agglomeration area. Based on the analyses of flood submerged area along the water areas and the spatial influence range from the sponge bodies, we optimized the layout of urban sponge bodies again. Accordingly, we can analysis the city construction path of Wugang.
