The Application Of Sponge City Technoloy In Henan Hebi Qi River Wetland Park Landscape Design

Sponge urban design is a new stormwater management system,the main objective is the construction of the negative impact of urban development on the hydrological environment is minimized,combined with the landscape to create a stormwater treatment,flood peak reduction by technical means decentralized,reduce surface runoff,non retention means of the project carried out on the rain,reservoir,osmotic,purification,use,emissions and achieve development cycle rainwater.The project to purify the wetlands as the basis,the integration of existing streams,ponds,low-lying land,adding rain gardens,grass shallow trench,permeable paving and other technical means,so that the series has become a strong absorptive capacity of the cavernous green to form a complete set of ecological and purify stormwater management system.This approach helps to reduce urban waterlogging disaster,after the rainy season there is still plenty of water,will become a wetland repositioned to achieve new ways of rainwater utilization.The sponge technology in urban wetland park site planning and design,it is possible to provide a fresh perspective on urban theory sponge thinking and design practice.
