冰川、雪、冻土、地下水、地表水和降水的水文过程一直是水文工作者共同关心的问题。本文通过对冰川、雪、冻土和地下水的同位素和水化学分析，研究了不同景观带的水文过程。其化学组成特征为：冰川雪带以Ca-HCO 3为主，高寒荒漠带以Mg-Ca-SO 4-HCO 3为主，沼泽草甸带以Ca-Mg-HCO 3为主，高寒灌丛带以Ca-Mg-HCO 3为主，山地草原带以Na-Ca-SO 4为主。采用端元混合模型进行过程线分离。结果表明，在冰川融化期，马坟沟河的补给量约34%来自冰川雪融水，约12%来自各景观带的冻土融水，约54%来自地下水。研究表明，马坟沟河融水主要来源于冰川雪融水、地下水和冻土融水。
Hydrologic processes of glacier, snow, frozen soil, groundwater, surface water and precipitation have always been the common concern of hydrologists. The purpose of this study is to identify the hydrologic processes in different landscape zones, based on the isotopic and hydrochemical analysis of glacier, snow, frozen soil and groundwater. The chemical compositions were characterized by Ca–HCO3in the glacier snow zone, Mg–Ca–SO4–HCO3in the alpine cold desert zone, Ca–Mg–HCO3in the marsh meadow zone, Ca–Mg–HCO3in the alpine shrub zone, and Na–Ca–SO4in the mountain grassland zone. The end-member mixing model was employed for hydrograph separation. The results showed that during the melting period Mafengou River water was recharged by glacier–snow melt water about 34%, thawed frozen soil water in each of the landscape zones about 12%, and groundwater about 54%. This study suggested that Mafengou River water during the melting period was mainly recharged by glacier–snow melt water, groundwater and thawed frozen soil water.
