在开展1/20万田林幅及乐业幅水文地质普查工作中,我们对百郎地下河系进行了调查,得到一些肤浅认识,现作一介绍。 百郎地下河系由主流和11条支流构成,主流发源于乐业县甘田公社达浪村,经达坡寨后成明流,在伏流洞消入地下,穿山绕岭,经白竹洞、弄洋、河坪、杨柳井、石龙背、出口位于幼平公社百郎村南3.5公里。主流长64.2公里,支流共计长度159公里。流域面积835.5平方公里。出口最小流量2.0387米~3/秒,最大流量121米~3/秒,枯水期平均流量3.182米~3/秒,为一大型地下河系。是红水河上游的一条“支流”(图1)。
During the 1 聽 000 000 000 000-foot Tianlao Geographic Survey of Hydrogeology, we conducted a survey on the Bailang Underground River System and obtained some superficial understandings. The Bailang underground river system consists of the mainstream and 11 tributaries. The mainstream originated in Da Long Village, Gantian Community, Leye County. After reaching the slope, it flows into the Ming River. Ocean, Heping, Yangliujing, Shilong back, Exit 3.5 km south of Bailang Village, Kindergarten. The mainstream of 64.2 km long, a total length of 159 km tributaries. The basin area of 835.5 square kilometers. The minimum flow rate of export is 2.0387m ~ 3 / s, the maximum flow rate is 121m ~ 3 / s, the average flow rate in dry season is 3.182m ~ 3 / s, which is a large underground river system. Is a “tributary” upstream of the Red River (Figure 1).
