遥感技术在艰险山区地质灾害调查中的应用

Application of Remote Sensing Technology in Geological Hazard Investigation in Difficult and Dangerous Mountainous Areas

本文在分析遥感技术应用现状的基础上,采用“遥感解译+现场调查”的技术方法,对新疆且末县阿克苏库勒湖流域内泥石流、滑坡、崩塌等地质灾害的发育情况进行了详细的解译分析,显示区内泥石流灾害最为发育,以阿克苏库勒湖湖口泥石流及其湖口下游垭口处泥石流为典型。通过近30年遥感影像对比分析,显示区内泥石流堆积体多处于稳定状态,但受湖水持续上涨威胁,阿克苏库勒湖存在溃堤风险,对安迪尔河下游人民群众生命、财产安全存在一定威胁。

Based on the analysis of the application status of remote sensing technology,this paper adopts the technical method of“remote sensing interpretation+field investigation”.theevelopment of geological disasters such as debris flows,landslides,and collapses in the AksuKule Lake Basin in Qiemo County,Xinjiang was analyzed in detail.It shows that the debris flow disasters are the most developed in the area,with the debris flow at the mouth of AksuKule Lake and the debris flow at the lower pass of the lake mouth as a typical example.Through the comparative analysis of remote sensing images in the past 30 years,it is shown that most of the debris flow deposits in the area are in a stable state,but due to the continuous rise of lake water,there is a risk of dyke rupture in AksuKule Lake,there is a certain threat to the safety of people's lives and property in the lower reaches of the Andir River.
