| 摘 要： | 通过对近50 a塔里木河源流区径流、温度、降水量的年代际分析,探讨了过去半个世纪塔里木河源流区气候变化及其对河川径流的影响。研究结果显示,在过去50 a里,塔里木河三源流径流量总体呈现增加的趋势,尤其体现在20世纪90年代以后,丰水年出现次数较多;对径流和降水量与温度作相关分析可知,随着温度的逐年代升高,其对径流量的影响越来越显著。蒸发量随着温度的升高也在逐渐增大,但是降水量的增长速率远大于蒸发量的增长速率,所以即使蒸发量的增加也不足以使径流量减少。

| Abstract: | The authors analyzed the decadal variation of runoff,temperature,precipitation in the headwaters of the Tarim River during the last 50 years,so as to discuss the climatic change and its influence on river runoff.It was found out that the runoff volume of the three headwaters of the Tarim River generally showed increasing tendency in the past 50 years,especially,there were more high-water years after 1990s.Correlation analysis between precipitation,temperature and runoff showed that increasing temperature ex... |
