| 摘 要： | 利用1981~2012年黑河上游地区气温、降水、蒸发以及径流实测资料,运用统计学方法分析了黑河上游32年来气候和径流变化特征。结果表明:(1)近10年温度显著升高,蒸发量有明显减少;(2)降水与径流量呈不显著的增多趋势;(3)降水是影响黑河上游地区径流量增加的主要因子,年径流量的微弱增加主要是由于夏季降水量的增加以及其蒸发量的减少造成的。

| Abstract: | Based on the measured data of the temperature， precipitation， evaporation and runoff of the Upper Heihe River from 1981 to 2012， the variation characteristics of the climate and runoff therein for 32 years are analyzed with the statistical method. the result shows that（1）In recent 10 years， the temperature rises obviously along with the significant decrease of the evaporation;（2）the precipitation and runoff show an inapparent increasing tendency;（3）the precipitation is the main factor to influence the increase of the runoff within the region of the Upper Heihe River， while the slight increase of the annual runoff is mainly attributed to the increase of the precipitation and the decrease of the evaporation in summer. |
