摘要
遥感是目前滑坡灾害管理的重要手段,文中利用预处理后的高分辨率影像和地形地貌、地质构造、历史滑坡灾害信息及其分布的环境地质数据,研究该地区滑坡的典型影像特征,建立了滑坡的位置、形状、线性特征、微地貌等解译标志,在影像上确定了部分滑坡的位置、类型、边界。最后文章对影像上最小可确定的滑坡大小进行了讨论。
Remote sensing is very important means for regional landslide investigation.In this paper,high-resolution image after pretreatment,terrain and relief data,geological data,history landslides and their surroundings data are used together to analyze landslide.Through these information typical image characters are described and summarized in this area.Then interpretation signs such as landslide position,its shape,linear characters and micro-relief are built in the research.With these signs some landslides can be sketched out in the image.At last,the least size of landslide which can be seen in satellite image is discussed in the article.
