摘要: 黄河尖扎县境内流域梯级水电站的建设,使沿岸原有的崩滑体前缘大多数被淹没,处于回水变动带的崩滑体稳定性有所降低,产生一些新的崩滑体,给当地人民造成经济损失.研究工作采用遥感技术手段,快速地调查该地区现有的地质灾害类型、数量及表现形式,以及地质灾害与地质环境条件的相互关系,从而为在该地区进行地质灾害防治工作提供基础资料,取得了良好的应用效果.

Abstract: The step dam development in Jianzha county of the Yellow river Has caused most of the frontage of landslides to be submerged. Old coll apses and landslides lost stability. Some new collapses and landslides will be produced. This brings direct threat to production and living of the local people and seriously influences sustainable social and economic development. In this study the types, quantity and manifestations of existing geologic hazards in the urban study area and the interrelations between geologic hazards and geological environment term were ascert ained rapidly by using the remote sensing technique, thus offering an accurate and reliable basis for the prevention and control of geolo gical hazards in the area. The application of the remote sensing technique yielded good results.
