Research On The Rainwater Reuse Of Urban Park Landscape In Chengdu City

Chengdu is a city that is born with water, the river is rich in water resources, and it is very rich in rainwater resources. But Chengdu is also a water shortage city. With the development of urbanization, the shortage of water resources and the pollution of water environment seriously restrict the realization of the goal of rural urban construction in Chengdu and the sustainable development of the city. Urban park is an important part of the construction of urban green space, and it is also an important carrier for the utilization of rainwater resources. In the urban park landscape design,how to combine the use of rainwater resources, to create the form of the United States and the United States and the ecological environment of the rain type green space, is one of the purposes of this study.In this paper, the rainwater utilization landscape as the principle, through the analysis of building background conditions and regional characteristics in the rain type greenbelt in Chengdu City, the characteristics, the park in Chengdu city rainwater utilization methods and specific operation methods are summarized. At the same time,draw lessons from domestic and international rainwater utilization landscape of outstanding cases, summed up the Chengdu park green space construction of rainwater utilization strategy and methods. Through three different levels of macro,micro and macroscopical level, three different modes of rainwater utilization,transportation and storage, the management and application of stormwater management in the landscape construction of Chengdu park green space were discussed. Finally, a comprehensive research and analysis of a park green space in Chengdu city was carried out, and the application mode of rainwater harvesting planning and design method in the planning and design of green space was discussed.It is at the beginning and development stage of Chengdu city park green spacerainwater utilization, there is no definite regulation of the specific design content and method, the rainwater utilization is an important function as the landscape construction of Chengdu City, hoping to provide reference with sponge City, build green city form beauty and ecological beauty.
