A Study On Design Of The Low Impact Development Rainwater System In The City Comprehensive Park Under The Background Of Sponge Urban System

With the rapid development of global climate change and urbanization,the problem of urban rainwater is becoming more and more serious,which is reflected in water ecology,water resources.water environment,water security and water culture.As an important part of green space system,urban comprehensive park plays an important role in alleviating the problem of urban rainwater,but there are many problems and shortcomings.In the context of the country vigorously promoting the construction of the Sponge City,breaking through the limitations of the traditional rainwater system in the city park,the construction of the rainwater system with low impact development is studied.From specificing design goals,stablishing design principles and strategies,analysing the status quo,selecting facilities,constructing system,and then combining the low impact development of rainwater system with landscape elements are all detailedly explained.Summe up the design method of low impact development rainwater system in the city comprehensive park under the background of city sponge in order to provide reference value for future research.Finally,the theory is applied to the practice,taking Yongshun Liu Zhuang Park in Beijing,Tongzhou as an example,to realize the construction of rainwater system with low impact development in the urban comprehensive park..
