中文摘要	利用黑河流域东部子水系中上游10个水文站近60年气温、降水、蒸发观测资料,分析3个要素地域和年际变化特征。结果表明:(1)气温总体地域变化特征表现为从南向北随着海拔高程逐渐降低,多年平均气温呈现逐步升高的趋势。2000年以后气温平均升高0.9℃;(2)降水量总体地域变化特征表现为从南向北、从东向西随着海拔高程的逐渐降低,多年平均降水量呈现逐步减少的趋势。各站历年降水过程呈锯齿状高频振荡,深山区、走廊平原区(荒漠边缘区)降水量长期变化总体上是呈缓慢上升的趋势,浅山区降水量长期变化总体上是呈缓慢下降的趋势;(3)蒸发量地域分布规律跟降水量、气温地域分布规律密切相关,蒸发量总体地域变化特征表现为从南向北随着海拔高程逐渐降低,多年平均蒸发量呈现逐步增大的趋势。1980~2011年间深山区多年蒸发量变化趋势平稳,无明显增大或减小的变化趋势;浅山区和走廊平原区均呈现出蒸发量逐年减小的总体变化趋势。
英文摘要	The regional and interannual change characteristics of three elements were analyzed based on the observed data of temperature, precipitation and evaporation from the 10 hydrometry stations in the upper and middle reaches of the eastern sub-rivers in the Heihe River Basin in the recent 60 years. The results show: (1) The mean annual temperature gradually increased with the altitude from the south to north decreasing, and the temperature increased by 0.9℃ in average since 2000. (2) The mean annual precipitation gradually decreased gradually with the altitude from the south to north and from the east to west decreasing. The precipitation hydrographs of the stations are serrated in high-frequency oscillation over the years. The precipitation has a long trend of slow increase in the deep mountain area and plain of corridor (edges of desert), while the precipitation has a trend of slow decrease in the hilly area. (3) The geographical distribution of the evaporation is closely related with the precipitation and temperature distribution, and the mean annual evaporation gradually increased with the altitude from the south to north decreasing. There was no big change of the mean annual evaporation in the deep mountain area from 1980 to 2011, while there was a trend of evaporation decreasing in the hilly area and plain of corridor.
