气候变化与水文循环之间有着密切的关系,分析了位于新疆北部玛纳斯河流域近期的径流、降水、气温、蒸发以及永久性积雪面积的变化,提出气温、蒸发、降水变化影响到玛纳斯河年径流的变化,水量变化与气候变化相关;1996年以来,气温升高对径流变化影响显著;气温升高使永久性冰川雪地面积减少,融雪水大量补给径流,但随着气温的持续上升,因气温升高造成径流量增加的程度将减弱。
There is a close relationship between climate change and hydrological cycle. The changes of runoff, precipitation, temperature, evaporation and permanent snow cover in the Manas River basin in the northern part of Xinjiang were analyzed. The changes of temperature, evaporation and precipitation were also analyzed Changes in annual runoff of the Naas River, and changes in water volume are related to climate change. Since 1996, the effects of elevated temperatures on runoff have been significantly impacted. Increased temperatures have led to a decrease in the area of permafrost glaciers and a large supply of slush water. However, Will continue to rise, the degree of runoff increase will be weakened due to the rising temperature.
