Design And Practice Of Roof Greening In Dongguan City Based On Rainwater Resources

Water is the source of life,the development of the present,in the modern development and production process of the modern society plays an increasingly important role.At the same time,the use of human activities in the process of water resources not only consumes a good stock of water,but also cause pollution of the water efflux.Therefore,how to save water resources and the sustainable development of water resources is the focus of our attention.The use of water resources in the design of building energy saving design and the efflux is an important indicator.And in the actual operation of the process,in addition to the drinking water,wash,clean and ecological water occupies the total building with more than 60%of the water.Therefore,through the rational planning of rainwater and other recyclable water resources development and utilization is an alternative approach.Under such background,this paper takes the roof greening design of Dongguan City as the research example,analyzes and designs the rainwater resources construction target in the roof greening system and the garden greening system.According to the collection of rainwater,rainwater storage and the application of rainwater and other aspects of the system to achieve.It is hoped that this study can effectively solve the problem of rainwater harvesting in the process of urban building greening,effectively solve the resource shortage caused by urban expansion,and effectively reduce the consumption of building water resources to achieve the goal of energy saving and emission reduction.At the same time,it is hoped that the research of this paper can provide the necessary theoretical basis and practical guidance for the concrete realization of the related construction system and the optimization and upgrading.
