| In recent years,with the rapid increase of the level of urbanization and urban economy,the people’s living standard has gradually improved.However,with the rapid development of urbanization,urban environmental problems have become increasingly prominent.More and more urban green space is replaced by high-rise buildings,the city’s impervious area is expanding,the rain can not quickly penetrate the ground to supply the groundwater resource.The original ecological system has been destroyed.And with the imperfect flood control system,aging pipelines and other issues,frequent urban floods,water scarcity,ground subsidence and other ecological problems have emerged in the city,even the physical safety of urban residents is under threat.As the name card of a city,The urban comprehensive park shows the unity of material civilization and spiritual civilization.At the same time,it is an important part of the urban green space,which mostly supports construction of the sponge city.Therefore,the urban comprehensive park should also respond positively to the city flood disaster while satisfying people’s daily visiting,viewing and leisure activities.The purpose of this paper is to explore the rainwater harvesting green space in the urban comprehensive park on the background of sponge city.Through the research on the theoretical concept of sponge city construction and its related research resuhs at home and abroad,this paper discusses the LID technology under the background of urban development in our country.Futhermore,it will guide the concrete implementation process and method under the actual conditions of urban comprehensive park. |
