在对山西省娄烦县地质灾害调查的基础上,分析及整理了该县各种地质灾害的数量、分布情况,以及发生的原因。利用MAPG IS的空间分析功能,求取评价单元的潜在地质灾害强度指数与现状地质灾害强度指数,分级赋值进行换算叠加,获得评价单元的地质灾害综合危险性指数,据此将该区域地质灾害划分为3个区。最后根据调查区地质灾害形成的地质环境条件、地质灾害的分布和地质灾害易发程度,结合当地经济与社会发展规划等进行综合分析,划分出了地质灾害防治重点区和一般区。
Based on the investigation of geological disasters in Loufan County, Shanxi Province, this paper analyzed and sorted out the quantity, distribution and causes of various geological disasters in the county. Utilizing the spatial analysis function of MAPG IS, the potential geological hazard index of the evaluation unit and the current geological hazard intensity index and grading assignment are calculated and calculated, and the comprehensive hazard index of geological disasters of the evaluation unit is obtained. Based on this, For 3 districts. Finally, based on the geological environment conditions, the distribution of geological disasters and the degree of susceptibility to geological disasters caused by the geological disasters in the investigation area, a comprehensive analysis of the local economic and social development planning is made to draw the key areas for geohazard prevention and control and the general areas.
