福州市排水排涝整治思路研究刘超(福州市规划设计研究院,福建福州350003)摘要:近年来,福州市江北中心城区多次遭受大范围的内涝灾害。从城市化进程、气候变化、蓄水排涝设施、管理体制等角度分析福州市内涝灾害发生的原因,并通过模型计算得出不同设计暴雨标准下的福州市江北城区涝水量。根据福州特有的地形地貌及排水排涝系统建设进展情况,提出“清、建、分、扩、防”的排水管网和河道整治措施,通过方案对比,最终确定“清+分”为福州市排水排涝整治思路。关键词:排水排涝;福州市;整治思路中图分类号:TU992文献标识码:C文章编号:1000-4602(2014)03-0106-03StudyonImprovementIdeasaboutDrainageinFuzhouCityLIUChao(FuzhouPlanningDesignandResearchInstitute,Fuzhou350003,China)Abstract:Inrecentyears,theJiangbeicentralareainFuzhousufferedfromawiderangeofthewaterloggingdisastersrepeatedly.Thecausesofthewaterloggingdisasterswereanalyzedintermsoftheurbanization,climatechange,waterstorageanddrainagefacilities,managementsystemandsoon,andthewaterloggingquantityoftheareaunderthedifferentdesignrainstormcriteriawasachievedbythemodelcalculations.AccordingtotheuniqueFuzhoutopographyanddrainagesystemconstructionpro-gress,themeasuresforimprovingthedrainagenetworkandtheriver,including“dredging,building,by-passing,expandingandpreventing”wereproposed.Thefinaldrainageimprovementideas
