黔南独山地区是我国及世界上岩溶最发育地区之一。调查研究表明，该区地下水系发育，因此，开发利用岩溶地下水资源对当地经济持续发展至关重要。黄后地下水系位于独山地区南部，其主流全长56．5km，汇水面积445km2，洪水期地下水系总出口流量60m3/s以上，枯季流量1．55m3／s。本文主要介绍该地下水系的形成、分布、主要特征、地下水资源及其开发利用。
Qiannan Dushan area is one of the most developed areas in China and the world karst. Investigation and research shows that the groundwater system in this area is developing. Therefore, the exploitation and utilization of karst groundwater resources are crucial to the sustainable development of the local economy. The Huanghe groundwater system is located in the southern part of Dushan area. Its main stream is 56.5km in length and has a catchment area of 445km2. The total discharge of groundwater system is above 60m3 / s in flood period and 1.55m3 / s in dry season. This paper mainly introduces the formation, distribution, main features, groundwater resources and its development and utilization of the groundwater system.
