Keyword高山生态系统 水文 气象 卧龙地区 横断山区
Abstract

卧龙地区地处四川省阿坝藏族自治州的东南部,它是以保护大熊猫等珍贵动物和山地生态系统为重点的自然保护 区,面积约2000平方公里。
1981-1983年,中国科学院成都山地灾害与环境研究所在该地区展开了高山垂直带生态系统考察。考察中,设立了高山水文、气象观测站网,对该区水文气象状况作了较系统的观测。本文将其水文的时空分布特征、补给特点及水化学特征作了初步分析。

Other Abstract

In Wolong region annual total discharge is 2.02×109M3, of which annual total discharge of Yuzixi river makes up 70% and annual total of Shouxi river is 30%. Average runoff coefficient is 0.87.  Due to the influence of precipitation the runoff is large while the altitude is high. The high water period runs from May to October, six monthes. Not uniform coefficent of variation yearly of the region is not high (0.29). Variability coefficaient Cv of annuanl average discharge is very low (0.17). Maximum peak discharge modulus of Yuzixi and Shouxi rivers are 700 dm3/sec·km2 and 3171dm3/sec·km2, respictively. Minimum discharge modulus of them are 8.35 dm3/sec·km2 and 10.79 dm3/sec·km2, respictively, the sediment discharge is about 1.66×106 T/year. The river water is weak alkaline and comprised motly soft water and low mineralization water.
