云南南洞地下河系统及水资源开发利用

WATER RESOURCE DEVELOPMENT OF NANDONG SUBTERRANEAN STREAM SYSTEM YUNNAN PROVINCE

南洞地下河系统,流域面积986km^2。年迳流总量2.988亿m^3,是南盘江支流——芦江河的重要补给水源,流域由岩溶高原、断陷盆地,盆间丘陵几部分组成。中三叠统个旧组(T_2g)灰岩是主要含水层位。地下河系统由多条地下河组成,是早期南洞地下河与大黑水洞地下河经后期发展、演化、归并袭夺而形成。虽水文地质条件十分复杂,但资源丰富,开采潜力巨大,磨石沟地下筑坝,是最优的开发方案。

The system of Nandong subterranean streams is a major feeding source of Lujiang River, a tributary of Nanpan River. Its watershed area is consist of karst plateau, fault basins with hills inbetween. The system consists of many underground streams and forms after long historical development, evolution and piracy of Nandong a'nd Da Heishui subterranean stream. It has a great potential exploitation water resource. The most rational developing plan is to build an underground dam in Moshi Valley.
