摘　　要：目前国内关于避洪转移分析的系统性研究较少,尚未形成一套完整的技术理论体系。以GIS技术为支撑,基于洪水风险信息,通过对居民地、路网数据进行相交处理,以乡镇级行政区划约束下的距离最近原则划分转移单元,同时确定需要转移人口数量的空间分布;采用最优路径计算方法结合GIS网络分析功能确定转移单元至安置区的最优转移路线。最后以新汴河刘卫闸处溃堤洪水方案为例,研究受淹区避洪转移分析的技术应用,为防汛决策、安全转移提供技术体系支撑。Systematic studies on flood evacuation analysis are uncommon at home present and a complete technological and theoretical system has not been formed yet. Utilizing GIS as a technical support, the intersection condition of residential area and road network is analyzed based on flood risk information. The evacuated units are divided and the spatial distribution of the evacuated population is determined based on the principle of closest distance and constrained by township - level administrative divisions. Optimal route algorithms combined with GIS network analysis are utilized to determine the optimal routes from evacuationunits to shelters. In the case of the dam - break of Liuwei sluice on the left bank of Xinbian River,the concrete flood evacuation
