Design And Research Of Roof Garden Based On The Concept Of Rainwater Management

With the rapid development of urbanization,the urban construction land is expanding,the building density is getting higher and higher,the green land resources are getting less and less,the environmental problems are becoming more and more serious,which leads directly to the ecological imbalance in the city.In order to improve the ecological environment and improve the quality of life,People are constantly reconsidering new ways of greening.In this case,the design of the roof garden was born,and can not occupy the premise of urban land,to create a three-dimensional natural landscape and green space,to create a close to the natural place,it has been a widespread concern.With the expansion of real estate construction,more and more hard pavement on the ground,on the one hand caused the rainy season when the surface rain and the roof of the construction of the rain can not naturally penetrate the soil,the rain gathered in the hard pavement surface serious water The pressure of the municipal drainage network;the other hand,the natural rainwater falling to the surface,and then from the surface into the municipal drainage pipe network,so that the rain has not been a reasonable use,resulting in waste of water resources.Therefore,how to deal with the problem of urban water and the rational use of rainwater resources is the process of urbanization to solve the important issues.This paper mainly elaborates and analyzes the methods and measures of rainwater management in roof garden,studies the roof garden design for rainwater management,explores how the roof garden manages rainwater resources and the roof garden rainwater circulation system.The roof garden design How to play the usefulness and creativity of rainwater management to carry out a useful exploration,and strive to roof garden landscape design opened up a new way of thinking.Finally,this paper will return to the theory of practice,the roof garden rainwater management theory and graduation design closely together to express the relationship between roof garden and rainwater management is how to show in the design.The innovation of this paper is to try to combine the traditional roof garden landscape with the rainwater management function,so that the two achieve a high degree of combination of theory and practice.Through the analysis and research on the various elements and technical requirements of the roof garden,we will show a roof garden with functional,aesthetics and ecology to create a beautiful and comfortable landscape environment.
