彝良县位于云南省东北部,为云南省七个地质灾害重点防治区的一部分.2003年的地质灾害调查显示,县域内有地质灾害236处,其中滑坡181处,不稳定斜坡9处,泥石流34处,地面塌陷12处,以滑坡和泥石流为主.综合研究分析结果表明,地质灾害的主要诱因除地质地理环境(地形地貌、降雨集中、岩溶作用、新构造运动强烈)等自然因素外,人类工程活动中的切坡过陡和采矿活动形成的巨大采空区也是主要诱发因素.在此基础上,根据各种影响因素的作用强度把彝良县划分为洛泽河-小米溪河高易发区、发达-洛旺中等易发区和低易发区(含小草坝亚区和龙街-奎香亚区)三个地质灾害区,并在灾害防治、协调管理、宣传教育等方面提出了一些有益的建议.

Situated in the northeastern of Yunnan province, Yiliang county belongs to geological hazards pivot prevention and control region of Yongshan-Yiliang landslides and debris flows and one of the seven geological hazards pivot prevention and control regions in Yunnan. The geological hazard investigation in 2003 showed that there were 236 geological hazards, including 181 landslides, 9 unstable slopes and 34 debris flows as well as 12 collapses. Moreover, the landslides and debris flows were dominant disasters in this research area.The results from comprehensive analysis indicated the geological hazard mainly resulted from not only geological and geographic environment factors, such as landform and relief, rainstorms and karst as well as neo-tectonic movement, but also slop-cutting and huge goafs in mining areas by human activity. On the basis of the intensity of several influences, three types of geological hazard region are divided, including high susceptible area in Luoze River-Xiaomixi River, middle susceptible area in Fada-Luowang and low susceptible area in Xiaocaoba and Longjie-Kuixiang. Furthermore, the authors put forward some constructive suggestions for the prevention, control and management as well as publicity and education on geological hazard.
