摘要
堆龙德庆区位于青藏高原腹地,水系发育,新构造抬升强烈,地质环境条件复杂,地质灾害调查工作程度较低。为摸清地质灾害发育情况和孕灾背景,通过1∶50000地质灾害详细调查,发现区内地质灾害种类齐全,现有地质灾害143处,主要为泥石流、崩塌、滑坡、不稳定斜坡和河岸坍塌。研究发现地质灾害的发育与地形地貌、地质构造、水系、岩土体类型、斜坡结构类型、植被、降雨、人类工程活动等因素关系密切。通过调查研究有效的提高了堆龙德庆区地质灾害研究程度,为防灾减灾提供了技术支持。
The Duilong Deqing country is located in the hinterland of Qinghai-Tibet Plateau,Water system is developed,neotectonic uplift is intense,geological environment conditions are complex,and the degree of geological disaster investigation is low.In order to find out the development situation and background of geological disasters,through the detailed investigation of geological disasters,it is found that there are a complete variety of geological disasters in the area,including 143 existing geological disasters,mainly debris flow,collapse,landslide,non-slope and riverbank collapse.It is found that the development of geological hazards is closely related to topographical features,geological structures,water systems,types of rock and soil mass,types of slope structures,vegetation,rainfall,human engineering activities and other factors.Through investigation and study,the research degree of geological disaster in Duilong Deqing district was effectively improved,and the technical support for disaster prevention and reduction was provided.
