摘要:
本文以地质灾害高发的西藏芒康县为例,基于高精度遥感解译和地面调查综合获取灾害数据,全面查明了区内斜坡地质灾害分布特征。引入坡度、起伏度、坡向、地质构造、地层岩性、河流水系(干流、支流)、植被覆盖8个影响因素做为评价因子,采用信息量模型及其加权模型两种模型进行斜坡地质灾害易发性评价。研究结果表明:遥感解译正确率高达96.8%,加权信息量模型在该区适用性更好。芒康县地质灾害高易发区面积1317.8km2,主要分布于澜沧江、金沙江及其主要支流河谷两岸及地质构造密集发育部位。本文完整论述了高海拔山区开展区域性地质灾害全面调查与易发性评价的全过程,为类似地区开展区域地质灾害调查评价工作提供了技术参考。
Abstract:
Taking Mangkang County of Tibet where geological disasters largely occurred as an example, based on high-precision remote sensing interpretation and ground survey, the distribution characteristics of slope geological hazards in the area are comprehensively identified. Eight typical factors are selected as evaluation factors including slope, relief, slope direction, geological structure, stratum lithology, river system (main stream, tributary) and vegetation coverage, so that the evaluation model based on information model and weighted information model is established to analyze landslide susceptibility. The results show that the accuracy of remote sensing interpretation is as high as 96.8%, and the weighted information model has better applicability in this area. The statistical results indicate that the areas with high susceptibility taking up 1317.8km2, which mainly distribute on the valley of Lancang River, Jinsha River and its main tributary river and the densely developed areas of geological structures. This paper describes the theoretical methods and technical route of hazards susceptibility evaluation in high elevation mountain area, which provides a technical reference for similar areas.
