当前,空间遥感技术在各个领域得到了广泛的应用。水利水电建设中为研究泥沙运动规律,预报洪水,水利区划以及解决水文地质工程地质问题,也取得了不少成果。笔者在红水河、桂江流域规划中,初步开展了此项工作。利用美国1、2号陆地卫星多波段扫描象片进行地质解译,编绘了地貌、线性构造,岩溶地层分布和植被图,对区域构造稳定及工程地质条件获得了一些新的认识,并以较快的速度提供了供规划设计用的资料.本文首先概述遥感的基本知识和卫片解译原理,然后介绍红水河、桂江流域地质解译方法及成果。
At present, space remote sensing technology has been widely used in various fields. In the construction of water conservancy and hydropower, a lot of achievements have also been made in order to study the law of sediment movement, forecast floods, water area zoning and solve hydrogeological engineering geological problems. The author in the Red River, Gui River basin planning, initially carried out this work. Geological interpretation of Landsat 1, 2 terrestrial satellite multi-band scanning images was used to map the topography, linear structure, karst formation distribution and vegetation map. Some new understandings were obtained for regional structural stability and engineering geological conditions. Based on And provides the data for planning and design at a faster speed.This paper first outlines the basic knowledge of remote sensing and the principles of satellite interpretation, and then introduces the geological interpretation methods and results of Hongshuihe and Guijiang watersheds.
