Abstract: The factors of the mountainous region geology disasters are firstly discussed．And then through the analysis on ge- ology disaster history and the present situation，the predominant type and the harm，the production environment and distri- bution regular in Chongqing mountainous region，it is thought that the terrain slope，the ground elevation diference and the gneiss engineering geology type are the main factors which affect the landslide．The active break is the main influence factor of the mud-rock floWproduction．The neWtectonic movement type and the intensity are the serial factors of the Chongqing landslide and the mud·rock floWactivity． Finally，the preventing and controlling measures are proposed and discussed， which has certain instruction significance to the preventing and controlling measures of geology disaster in Chongqing moun- tainous region．

Key words: geological calamity of mountainous region, influence factor, countermeasures of preventing and curing

摘要： 从重庆市山地地质灾害影响因素人手，通过对重庆市山地地质灾害的历史及现状、主要类型及危害、生成环境 和分布规律的分析，认为地形高差、岩士体地质类型是影响滑坡的主要因素，断裂是影响泥石流生成的主要因素，新 构造运动类型和强度是控制重庆市泥石流、滑坡活动的本质因素。并提出相应的防治措施，对重庆市山地地质灾害 的防治具有一定的指导意义。
