南洞地下水系统是云南省东南部一个较大的岩溶地下水系统,开发研究程度较低。尤其是高原岩溶区,属该系统的补给区,研究程度更低。采用遥感手段来研究与地下水有关的地质构造、地层岩性、地形地貌、岩溶水文地质现象等,实践证明是有效的。可以取得地面工作难以取得的大量有用信息,且速度快,精度高,推动了水文地质工作的进展。一、概述利用1:50万的卫片对南洞地下水系统
South Cave Groundwater System is a large karst groundwater system in the southeastern part of Yunnan Province with a low degree of research and development. Especially the plateau karst area, which belongs to the supply area of the system, has a lower degree of research. Using remote sensing methods to study groundwater-related geological structure, stratigraphic lithology, topography, karst hydrogeology phenomenon, proved to be effective. Can obtain a great deal of useful information that is difficult to obtain in ground work, and has the advantages of fast speed and high precision, and promotes the progress of hydrogeological work. First, an overview of the use of 1: 500000 piece of South Cave underground water system
