地下河是我国南方岩溶地区最重要的岩溶现象之一,也是地下水赋存的一种独特形式,它是南方各省碳酸盐岩地区主要的供水水源,也是矿山建设的主要威胁。因而,地下河成了岩溶地区水文地质工作研究的主要对象,它的分布埋藏、水质、水量、开发治理就成了研究的主要课题。地下河是由错综复杂的管道系统组成,其结构特征不单控制着地下河的分布,而且也影 Underground river is one of the most important karst phenomena in the karst area of ​​southern China. It is also a unique form of groundwater occurrence. It is the main source of water supply in carbonate areas of southern provinces and also a major threat to mine construction. Therefore, the underground river has become the main object of hydrogeological research in karst areas. Its distribution and burial, water quality, water quantity and development and management have become the major topics of research. Underground river is composed of intricate pipeline system, its structural characteristics not only control the distribution of underground river, but also shadow
