摘要
安图县地质环境条件复杂,人类工程活动强烈,崩塌、泥石流、地面塌陷频发。选取评价因子对以上三类地质灾害的诱发因素打分,再进行网格剖分。采用综合指数法和Mapgis空间分析功能,得出三类地质灾害的易发程度分区图。最后通过叠加得到全区地质灾害易发程度综合区划。
Antu County, with complex geo-environmental conditions and intensive engineering activities, suffers from frequent collapses, mudslides and ground subsidence. Related evaluation factors are applied to score the factors triggering these geo-hazards. A zoning map is made in terms of the geo-hazard proneness wiht the use of comprehensive index method and Mapgis space analysis. A final comprehensive zoning for the whole area is obtained through superposition.
