Abstract:In Shanghai, the river network is dense and the urbanization level is high. The expansion of urban land has caused many rivers to be blocked or landfilled, which has reduced the area of lake water in the region. The water surface of river and lake is related to the ecological environment of the city and the safety of flood and waterlogging control. In urban development and construction, it is inevitable to fill and plug the rivers. In line with the related stipulations, it is necessary to prove and analyze the filling and plugging river, and compensate the water surface. By systematically combing and analyzing the relevant documents of river filling and plugging, and combined with the engineering experience, the key points of compiling the argumentation report of river filling and plugging and its change report are put forward, and the administrative approval process is summarized, which provide the ideas and references for construction units to submit the projects for approval, promote the optimization and adjustment of regional river network layout, improve the regional water surface rate and ensure the safety of regional flood control and waterlogging.
