陇东黄土丘陵地区地质灾害高度发育,严重威胁居民人身安全和财产安全,阻碍社会经济发展。本文在完成研究区地质灾害详细调查工作后,以环县西北部毛井、车道、芦家湾三乡171个不同类型的滑坡为研究对象,结合遥感解译及以往研究成果,经统计分析得出该区滑坡类型及特征,在此基础上对各类滑坡的影响因素和形成机理进行分析研究,初步获得了各类滑坡的影响因素和形成机理。将为黄土丘陵地区滑坡灾害防治提供一定依据,为进一步研究黄土丘陵地区滑坡发育演化规律奠定基础。
Longdong loess hilly region highly developed geological disasters, a serious threat to personal safety and property safety, hinder social and economic development. After completing the detailed investigation of geological disasters in the study area, this paper takes 171 different types of landslides in the wellbores, driveways and Lujiawan townships in the northwestern area of Huhuan County as the object of study. Combined with remote sensing interpretation and past research results, According to the types and characteristics of landslides in the area, the influencing factors and formation mechanisms of various types of landslides are analyzed and studied, and the influencing factors and formation mechanisms of various types of landslides are preliminarily obtained. It will provide some evidences for landslide disaster prevention and control in loess hilly region and lay the foundation for further study on the development and evolution of landslides in loess hilly region.
