The degree of geological hazards in Chenggong County is in general, but within the whole county have different levels of development and distribution. On the basis of the disastrous investigations and analysis for the study area, a combination of qualitative and quantitative methods to divide the area into three types according to geological hazard-prone district basis is used. In principle ;medium-prone,low-prone and non-prone,and then analyzed and evaluated them separately;meanwhile,according to the geological environment conditions,the type of geological hazards,and the intensity of human engineering activities are divided the area into two types:the most important prevention area and common prevention area.%呈贡县地质灾害发育程度一般,但在全县范围内均有不同程度灾害发育分布.通过区内地质灾害的系统调查与分析,根据地质灾害易发分区依据、原则,采用定性与定量相结合的方法,对地质灾害进行了易发性分区.将全区划分为:中易发区、低易发区和非易发区,并分别进行了分析与评价；同时,根据呈贡县地质环境条件、地质灾害类型和人类工程活动强度等各种因素,将呈贡县地质灾害防治划分为重点防治区和一般防治区.
