Research Of Rain Garden Design In Campus Of Cold Area Based On Eco-revelatory

With the rapid development of urbanization,and the increase of impervious road surface and buildings,the underlying surface of the city has been changed.The surface runoff increased,non-point source pollution discharged into the river,the pollution of the river has been increased deeply.As a solution,Xi Jinping put forward the purpose of building the Sponge City.And the rain garden is one of the 21 technical measures of the Sponge City.The research object of this paper is the rain garden in campus of cold area,and taking the rain garden design of Shenyang Construction University as an example,studying strategies and methods of rainwater garden construction in campus of Northeast China based on eco-revelatory design.On the one hand,hope that through the application of rainwater garden,to alleviate the rainwater runoff and runoff velocity,purify water,improve water utilization,optimize the development of water resources,and create a more ecological campus landscape.On the other hand,hope that through the construction of the rain garden in the campus,to promote students' awareness of the ecological environment,and to build a sense of environmental protection.
