Research on the Regional Flood Disaster Prevention Path Based on the Multi-Source Flow Membrane Model

Abstract

It had occurred frequently to the flood disasters in recent years, and the scope of influence has been expanding, causing serious casualties and economic losses to the global climate change. It introduces the multi-source flow model in order to analyze the factors of the flood and the waterlogging prevention and control and the degree of synergy. According to the coupling relationship between the flood and the waterlogging prevention and the multi-source flow model, it is divided into the factors of the flood and waterlogging disaster to the water flow, the information flow, the facility flow, etc. According to the synergistic relationship of the influencing factors, it is constructed to the multi-source flow model of flood and waterlogging prevention and control. At the same time, it is established an evaluation index system of three categories, 10 categories and 21 categories of flood and waterlogging prevention and control synergy. Through the calculation of the degree of synergy, Clarify the problems in flood disaster prevention and control, and propose the path of "the water flow, the information flow, and the facility flow" for the flood disaster prevention and control. The proposed path of the regional flood disaster prevention and control based on the multi-source flow model can't only control the flood disaster from multiple aspects, but also ensure the synchronization of flood disaster prevention and control elements, and achieve the combination of disaster prevention social construction and flood prevention and control during disasters, It will provide new methods and technical support for the flood disaster prevention and control in China and the world, and ensure the sustainable development of cities and society.
