摘　　要：在对思茅区地质灾害进行详细调查的基础上,采用信息量法和模糊综合评判法分别对地质灾害进行危险性分区评价,并对两种评价结果进行了对比和综合分析。研究表明:在大部分地区两种评价结果一致且与实地调查结果吻合度高;地质灾害高度危险区主要分布在山区居民集中的沟谷山坡地带以及交通相对便利的公路沿线地区,低度危险区主要分布在地势相对平坦的盆地一带以及自然保护区;在局部地区,信息量法评价结果相对模糊综合评判结果与实地调查结果的吻合度更高。Based on detailed investigation of geological hazards in Simao District, the geological hazards risk as- sessment was carded out using information model and fuzzy comprehensive evaluation model, then, two evaluation results are compared with each other on figures and lists. Studies had indicated that the information model evaluation results was consistent with fuzzy comprehensive evaluation results in most of the region, which had a high degree of agreement with the results of field survey ; and the high - risk zone of geological hazard mainly distribute in the mountain valley hillside where hillmen resident in, as well as the relevant convenient transport ar- eas along the highway ; the low - risk zone of geological hazard mainly concentrate on the basin where the terrain is relatively flat and Nature Reserve; and there is a higher matching degree between the information model evaluation results and the actual investigation results than fuzzy comprehensive evaluation results in the local area.
