摘要
对贡嘎山高山水文观测试验系统进行了简要介绍,并对海螺沟冰川河以及黄崩溜沟的径流特征进行了初步探讨。由于大气降水同是冰川河及黄崩溜沟径流的重要补给来源,故其径流量的季节变化明显带有大气降水过程的烙印,显得丰、枯分明。在冰川河,冰雪融水和地下水在枯水季节的稳定补给改变了大气降水对冰川河径流的年内分配过程;在黄崩溜沟,由于冰雪融水和地下水对其径流的补给非常有限,大气降水过程对其径流过程的影响便明显大过冰川河。
Alpine hydrological observation in Mt. Gongga has been carried out for more than 10 years and has gained a large number of data. Also, a brief description of the observational system and an investigation of runoff of Huangbengliu Gully and the Glacial River in Hailuo Ravine are given in this paper. With precipitation being the major source, the runoff varies in seasons. In Glacial River, ice-melted and ground water offer extra provisions and change the annual distribution of the runoff; in Hangbengliu Gully, the same extra provision is in shortage and the precipitation plays a dominant role.
