四川新龙县滑坡地质灾害影响因素及分布规律分析
|
摘要
四川省甘孜州新龙县所处地质构造背景比较复杂,滑坡等地质灾害频繁发生,给当地人民群众生产生活和地方经济的发展带来了极大的阻碍甚至危害。文章以SPOT-6卫星数据对研究区的滑坡地质灾害进行解译,共解译滑坡灾害点203处。依据滑坡产生的内在因子、自然因子和人类工程活动,对研究区滑坡成因影响因素进行分析。根据滑坡灾害分布规律和规模将雄龙西乡以南到纳黑、博美乡以北到古鲁村、如几贡巴到卡哇西、觉吾乡以北到亚火乡及下坝村以西到中莫坝村列为地质灾害防治监测重点地区。
Xinlong county, Ganzi prefecture, Sichuan province, is located in a complex geological structure background,with frequent occurrence of landslides and other geological disasters, which has brought great obstacles to the production and living of the local people and the development of local economy. In this paper, the SPOT-6 satellitedata are used to interpret the landslide geological hazards in the study area, and 203 landslide hazard sites areinterpreted. According to the inherent factors, natural factors and human engineering activities of landslides, theinfluencing factors of landslides in the study area are analyzed. According to the distribution law and scale of landslidehazards, the key areas of geological hazard prevention and control are from Xionglong Xixiang to Nahe, Bomei to Gulu village, from Guigongba to Kawaxi, from Juewu to Yahuo village and from Xiaba village to Zhongmoba village.
