【摘要】：我国东南地区由于受季风气候影响,每年汛期受洪涝灾害威胁较大,随着城镇化进程快速发展,人口和财产快速聚集,洪涝灾害损失也日趋增强,如何协调流域经济发展与洪涝灾害之间关系,是当前城镇化发展中亟待解决的一个重要问题。而借助洪水风险图开展洪灾风险评估,可在一定程度上避免经济发展下洪水危害损失,同时对区域经济持续发展中城镇建设和企业布局有着重要指导作用。为此以经济快速发展的鄞东南平原为例,根据不同洪水位重现期对村镇居民、农田和工商企业造成的损失情况,从宏观和微观两方面分析了洪水风险与城镇经济发展关系。研究表明:洪水风险图一方面能够有效地反映不同等级洪水下的淹没情况,从而指导该区域的防洪减灾工作;另一方面可优化产业布局,指导产业园区不同产业类型的高程选择,从而有效缩小洪涝损失,确保地区社会稳定。因此编制洪水风险图对区域经济持续健康稳定发展具有重要意义。
[Abstract]:Due to the influence of monsoon climate, the southeast region of China is threatened by flood disaster in flood season every year. With the rapid development of urbanization and the rapid accumulation of population and property, the loss of flood disaster is increasing day by day.How to coordinate the relationship between river basin economic development and flood disaster is an important problem to be solved in the development of urbanization.The flood risk assessment by means of flood risk map can avoid flood damage loss to a certain extent and play an important role in urban construction and enterprise layout in the sustainable development of regional economy.This paper takes the rapid economic development of Yin Southeast Plain as an example and analyzes the relationship between flood risk and urban economic development from macro and micro aspects according to the losses caused by village and town residents farmland and industrial and commercial enterprises during the recurrence period of flood water level.The results show that on the one hand, flood risk maps can effectively reflect the inundation situation under different levels of floods, thus guiding the flood prevention and mitigation work in the region; on the other hand, the industrial layout can be optimized.Guiding the height selection of different industrial types in industrial parks, thus effectively reducing flood losses and ensuring regional social stability.Therefore, it is of great significance to compile flood risk maps for the sustainable and stable development of regional economy.
