Abstract维西县位于滇西北横断山脉中段高山峡谷地带,地质构造复杂、地质环境脆弱、年降水量大且集中,决定了该区属地质灾害高易发区.受自然、气候和人类工程活动影响,全县境内滑坡、泥石流、崩塌等地质灾害十分发育,地质灾害时空分布不均,暴发时段集中在59月;暴发区域多集中在人口聚集的澜沧江干流、永春河、腊普河等河谷区域.通过网格划分、选取致灾因子及对主要致灾因子赋值的方法,将维西县按照0.0~7.5,7.5~15.0,15.0~25.0的区间划分为低、中、高易发区.其中,高易发区主要分布在澜沧江沿岸及永春河沿岸,占县境总面积40.43%,中等易发区分布在腊普河流域,占县境总面积6.99%,低易发区主要分布在澜沧江西岸和东岸部分区域,占县境总面积52.58%.
Other AbstractWeixi County is located in the North-west Hengduan Mountain, where there are complex geological tectonics structures and vulnerable geological environment. With abundance of heavy rainstorms and humans engineering project effect, those regions belong to the high hazard prone zone. Through statistics, the geological hazards show that with uneven temporal and spatial distribution, each village in this area has whole disaster tapes which outburst concentrated mainly from May to September;the disaster affected areas are focused on the high population regions as Lancang River, Yongchun River and Lapu River. According to meshing and fixed hazard factors to special value, we can divide the Weixi County as low, medium and high hazard prone area on condition of the value 0.0 7.5, 7.5 15.0, 15.0 25.0. Among it, the high hazard prone area is mainly distributed along the Lancang River and Yongchun River, which account for 40.43 percent per whole county, the medium hazard prone area is sited in the Lapu River watershed, which account forf 6.99 percent, while the low hazard prone area is distributed in the West and East part of the Lancang River, which account for 52.58 percent per Weixi Land.
