Study on the Construction Mode of Ecological and Sustainable Rain Flood in New Urban Area of China

Abstract

In the background of the urbanization process has exceeded 58% of China and expansion of the construction land expansion, as a future appropriate residential development and ahead of the key area of urban rain flood management, this research expounds the new cities and new district how to follow the principle of ecological priority in different application field, and how to use land for urban green space and ecological protection for elastic development and rain flood management. The study of the new cities’ eco-rain flood management model is of great significance for the governance and sustainable development of urban diseases in China.By combining natural ways with artificial measures, planning is carried out in advance.On the premise of ensuring the safety of urban drainage and waterlogging prevention, the accumulation, infiltration and purification of rainwater in urban areas can be realized to the maximum extent, and the utilization of rainwater resources and ecological environment protection can be promoted in new cities. To make plan ahead,to avoid the problems of rain and flood in existing urban areas, and improve the livable quality of new cities greatly.New ways of thinking and construction guidance are proposed for ecological livable construction and flexible rain flood management of new urban areas in China.
