独山黄后岩溶地下水系发育特征及资源开发利用

An Investigation of the Huanghou Subterranean Drainage in Dushan County, Southern Guizhou and Proposals to Utilization of the Groundwater Resources

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。

The Dushan area of southern Guizhou is one of the world's best intensively karstified regions, where is well developed the subterranean drainage - the Huanghou drainage whose stemstream is 56. 5 km long with a catchment area of about 445 km2 and in the total groundwater yield of60 m3/s during flooding season; 1. 55 m3/s, in low-water season. It is obvious that the exploitationof groundwater there plays an essential role in the local sustainable development program. This paperpresents an investigation of the Huanghou subterranean drainage in its pattern and evolution and givesa proposal to reasonable utilization of the groundwater resources in the area.
