Research On The Campus Planning And Design Based On Sponge City

In recent years,with the development of urbanization in our country,the original nature of hydrologic circumstance has been destroyed which may cause many cities confronted with severely stormwater problems.For this purpose,we put forward the concept of “sponge city”,using Low Impact Development technology to carry out rainwater runoff control.As a special land in the city,the campus has a good site condition and green space,which is conducive to construct the green infrastructure.In this paper,in the sight of stormwater management,redistributed the campus space to build a spatial pattern of sponge campus.From the perspective of design,through the optimization design of the cavernous space,improved the value of campus landscape.Also through the utilization of rainwater resource and security system,ensured the implementation of security of campus rainwater management.Firstly,this paper started from the rigorous rainfall flood problem which many cities always faced to and pointed out the role of campus in the construction of sponge city.Then the paper used the simulation model to verify fact that whether the sponge campus can effectively control the runoff,and launched the basic research of sponge city,relevant theory and practical experience to make clear the design process of sponge campus planning.Secondly,according to the characteristics of water cycle,from the level of the hydrological conditions and coupling relationship between sponge space and traditional function of the space,the paper divided the campus space into rainwater permeable space,conveyable space and storable space.Through this way,determined the spatial pattern of the sponge campus,and put forward the countermeasures of rainwater management on the sponge campus.On the basis of the above,through the reference of the theory and experience of the sponge city,build the design system framework of the sponge campus planningFinally,this paper used the simulation model to solve the runoff of rainwater problem in site.Also,it constructed the optimization design system of sponge campus,combining the vital elements of public space with sponge space,then put forward the optimization design strategy.According to the startegy of the utilization rainwater resources and the system of guarantee on sponge space can control and manage the rainwater more effectively,so as to achieve the goal of sustainable development.
