摘要
归纳总结黔东南黄平县地质灾害发育特征和分布规律,分析孕灾环境条件及主要孕灾因子权重,对地质灾害孕育、形成的环境条件进行分区,并有针对性地提出防控措施建议。结果表明,地质灾害的形成、发生与所处的环境条件密切相关,地形地貌、地层岩性和地质构造为主要的内在诱发因素,降雨则是主要的外部诱发因素,人类工程活动也是重要影响因素;将研究区划分为高、中和低孕灾区三个等级,其面积占比分别为23.2%、13.6%和63.2%。以期为该区地质灾害防治工作提供依据。
By summarizing the development characteristics and distribution law of geological disasters in Huangping County,southeast Guizhou Province,analyzing the environmental conditions of disaster-pregnant and the weight of major disaster-pregnant factors,the environmental conditions for the development and formation of geological disasters are divided,and targeted prevention and control measures are proposed.The results show that the formation and occurrence of geological disasters are closely related to the environmental conditions,the topography,stratigraphic lithology and geological structure are the main internal inducing factors,rainfall is the main external inducing factor,and human engineering activities are the important influencing factors.Through zoning,the study area is divided into three levels of high,medium and low pregnancy disaster areas,accounting for 23.2%,13.6%and 63.2%.It provides reference for the prevention and control of geological disasters in this area.
