摘要: 干旱区的高山寒区水文过程对气候变化特别敏感,冰川、积雪和冻土变化产生的水文效应对下游水资源供给具有重要影响. 以天山南坡清水河流域为研究区域,通过分析水文站径流变化,结合流域上游山区巴伦台的气象资料,研究了高寒流域在气候变化背景下径流过程的响应特征. 结果表明:降水变化决定着径流过程,但气温上升对径流产生额外影响;气温变化产生的径流变化对径流产生延迟效应,冬季径流明显增加. 南疆天山地区冬季积雪较少,产生的春季融水径流不明显;夏季降水和径流同期出现,使得高寒山区水文过程对固体降水变化不敏感;冻土退化产生的水文效应使冬季径流增加明显. 为应对气候变化对水文过程产生的影响,应加强山区水库建设,通过工程措施调节,保障持续的水资源供给和利用.

Abstract: The hydrological processes of the alpine cold regions are particularly sensitive to climate change in arid areas. The hydrological effects of glaciers, snow and permafrost changes have produced a significant impact on the downstream water supply. Take the Qingshuihe River Basin which located on the southern slope of Tianshan Mountains as the study area, by the analysis of the runoff changes, and combined with the meteorological data of the Baluntai Meteorological Stations in the upstream mountainous, the response characteristics of the alpine watershed runoff process in the context of climate change was studied. The results showed that, the runoff process is subject to the changes in precipitation, but there is an additional influenced on runoff by the temperature increasing. The runoff change resulted from climate change is delayed; there is a significant increase in winter runoff. The snow cover is less in Tianshan Mountains in the southern Xinjiang, and the runoff in spring is not obvious. The precipitation and runoff in summer occurs at the same time, which result in the hydrological process of alpine mountain is insensitive to changes in solid precipitation. The winter runoff increased significantly by the permafrost degradation. It should be strengthened to cope with the impact of climate change on hydrological processes that the mountain reservoir construction. And by the engineering measures regulation to safeguard sustainable water supply and use.

Key words: cold regions, hydrological processes, climate change, regulation, Tianshan Mountains
