摘要
崂山区地质环境条件复杂,人类工程活动强烈,崩塌、滑坡、泥石流地质灾害频发,严重威胁居民安全,影响旅游业发展。本文针对以上3类地质灾害,分别选择8个评价因子进行打分,然后进行网格剖分,再采用综合指数法并利用Mapgis空间分析功能,得出崩塌与滑坡、泥石流的易发程度分区,最后通过叠加得到全区易发程度综合区划,划分出高、中、低和非易发区,为地质灾害防治提供依据。
Laoshan district with complex geological environment conditions.Strong human engineering activities and frequent collapse,landslides and mudslides geological hazards,seriously threat to the safety of the residents,impact the development of the tourism industry.This article in view of the above three types of geological disasters,respectively selects eight evaluation factors for scoring.then by mesh generation,using Comprehensive Index Method and Mapgis's space analysis features,the occurrence level of collapse、landslides and mudslides geological hazards District Assessment are obtained.last get easy-happening degree comprehensive division by susperposition,divides into high easy-happening area,medium easy-happening area,low easy-happening area and not happening area,provides the basis for the prevention of geological disasters.
