【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。
[Abstract]:At present, there are few systematic studies on the analysis of flood avoidance transfer in China, and a complete set of technical theory system has not been formed. Based on flood risk information, GIS technology is used to intersect the residents' land and road network data. According to the principle of nearest distance under the restriction of township administrative division, the transfer unit is divided, and the spatial distribution of the population that needs to be transferred is determined. The optimal path calculation method combined with the function of GIS network analysis is used to determine the optimal transfer route from single element to resettlement area. Finally, taking the levee break flood scheme of Liuwei Gate of Xinbianhe River as an example, the technical application of flood avoidance transfer analysis in flooded area is studied. For flood control decision-making, safety transfer to provide technical system support.
