太湖流域防洪新形势及治理对策

New situation of flood control in the Taihu basin and measure study

太湖流域是我国经济最发达、人口最密集、城市化程度最高的地区之一,也是洪涝灾害威胁较为严重的地区。近20多年来,流域经济社会高速发展,下垫面剧烈变化,导致区域河网水位大幅度抬升,加之周边水情变化及极端天气影响,流域防洪面临较大风险与挑战。在系统分析流域防洪体系现状及面临形势的基础上,提出新形势下构建高质量现代化防洪减灾体系的思路,为流域经济社会高质量发展保驾护航。

Being one of areas having most developed economy,high population density and degree of urbanization,the Taihu Basin has been under the threat of flood and waterlogging disasters.Over the past twenty years,the basin has experienced a rapid development of economy and society.Due to the drastic changes in the underlying surface,it has led to a big rise of water level in the regional river network.Coupled with changes in surrounding water conditions and frequent extreme weather events,the basin has been encountered with increasing risks and challenges for flood control.Based on systematic analysis of current status and situation faced by flood control system,an idea of building high-quality and modern flood disaster prevention and reduction system is proposed under new circumstances,in order to safeguard and support high-quality socio-economy development of the basin.
