摘要 以TM影像获取的地质环境信息为基础,采用多因子赋值定量评价法对西南三江流域地质环境稳定性进行分析评价,将其划分为稳定区
、较稳定区、较不稳定区和不稳定区4个级别,为区域性地质环境遥感综合评价提出了新的思路和方法。

Abstract :Based on information of geological environment obtained by TM image and adopting the quantitative evaluation
method of multi-factor assignment, the authors analyzed and evaluated the stability of geological environment in the
Three-River basin and divided the region into stable area, relatively stable area, relatively unstable area and unstable
area. This study has put forward a new train of thought and method for regional comprehensive evaluation of geo-environment
based on regional sensing.
