摘要
利用GIS信息系统和降水实况资料，对发生在广西漓江的洪涝情况进行分析。通过对洪涝灾害进行实地调查，利用灾害风险评估技术，对漓江洪涝灾害进行风险区划，对洪涝灾害的防御措施进行探讨。漓江上游是广西的暴雨中心，汛期暴雨常造成漓江洪涝灾害，特别是5－6月份，每年基本上都有2～3次大面积的洪灾；沿江两岸都是洪涝灾害的高风险区；漓江洪水具有来得快，消得也快的特点；造成漓江致洪暴雨的天气形势主要是华南静止锋；加强上游降水量的监测和预报，加强上游水库蓄水错峰的调控能力，完善低洼地段防洪堤坝建设，可以有效地防御洪涝灾害。
Based on GIS information system and precipitation data,floods that happened in Lijiang River in Guangxi are analyzed.Through investigating on floods disasters of both sides of the river,and by using disaster risk assessment technology,risk zoning of the floods are achieved and the defensive measures are discussed.Lijiang River upstream is the rainstorm center of Guangxi,often causes floods in the heavy rains in flood season,especially in May to June,and basically have 2-3 times of large-area flooding every year.Both banks of the river are high risk areas of flood disasters.Floods of the river are characterized in coming and retreating fast.Southern China qua-si stationary front is the main weather situation of the rainstorms that inducing floods of Lijiang River.To strengthen the monitoring and forecast of upstream rainfall,to strengthen the regulation ability of water storage peak load of up-stream reservoirs,to perfect the dam construction of low-lying area flood control can effectively defence the floods.
