资源简介

摘要: 地表的线性构造和环形构造是断裂、褶皱和岩浆侵位等构造活动在地貌演化过程中产生的痕迹,因此对判别及综合分析构造特征具有重要意义。通过人机交互式的方法从多源遥感数据提取线性构造和环形构造信息,能够更客观全面地了解线性构造和环形构造总体和个体的几何形态,从而指示区域内构造活动特征。以西藏察隅吉太曲流域为例,根据Google Earth影像,Landsat 8/OLI影像 ,ASTER GDEM及高分辨率DEM的衍生数据在研究区内提取了具有聚类特征的3组线性构造以及大量环形构造。分析结果表明:工作区整体处在北西走向的右行走滑剪切带中,且吉太曲流向转向南西的构造仍处在相对活跃的阶段,可能会是工程地质不稳定区及地质灾害易发区。  关键词: 遥感;  吉太曲;  线性构造;  Landsat8;  DEM     Abstract: Linear Structures and Ring Structures are of great important to distinguish and analyze faults,folds and magmatic emplacement on the surface.Extracting linear structures from multi-source remote sensing data with the approach of Human-Computer-Interaction can understand the overall and individual geometrical characteristics of Linear Structures and Ring Structures objectively and comprehensively.Taking Jitai river as an example,three sets of Linear Structures with characteristic of clustering and abundant Ring Structures were extracted in working area based on remote sensing data from Google Earth,Landsat 8/OLI,ASTER GDEM and high-resolution DEM.The results of the analysis show that the working area is in a dextral shear zone with northwest direction and the southwest structure of Jitai River is still in a relatively active stage,which may be an unstable area of the engineering geology and the prone areas of geological disasters.
