会东县地区属泥石流重度危险区,现在仍有许多城镇、电站和交通设施受泥石流威胁。区内地质构造复杂、岩体破碎、新构造运动活跃、地震频繁,谷盆交错分布的地形特征,降水集中、干燥少雨的气候特点,再加上人类不合理的开发活动为泥石流的发育创造了有利的条件。受其影响,泥石流分布与地层岩性、地质构造、暴雨强度及人类活动具有空间和时间上具有一致性。综合区域的地貌因素、气象条件等致灾因子,对会东县泥石流危害性进行了分区。
Huidong County area is a severe danger zone of debris flow, and now there are still many cities and towns, power plants and transport facilities threatened by debris flow. The complexity of geological structure, the broken rock mass, active neotectonic movement, frequent earthquakes, topography of staggered valleys, climatic features of heavy rainfall and dry and rainy weather, combined with unreasonable human development activities created the development of debris flow Favorable conditions Affected by it, the distribution of debris flow is consistent in space and time with the lithology, geologic structure, intensity of storm surge and human activities. The hazard factors of debris flow in Huidong County were divided according to the geological factors and meteorological conditions of the integrated area.
