| 摘 要： | 文章采用气候倾向率方法，对羊卓雍措流域附近的浪卡子气象站1971年-2009年期间采集的气象资料进行分析。结果表明，羊卓雍措流域气温升高，降水量不显著增加，蒸发量有减少的趋势；从季节变化来看各季气温都有增加的趋势；从上世纪80年代开始，降水量除在冬季减少外，其余季节都在增加；而流域蒸发量在冬季呈增加趋势，其余季节都在减少。

| Abstract: | The meteorological data bewteen1971 and 2009 from the Nagarze Climate Station nearby the Yamdrog Yumtso was analyzed by using modern climate statistical methods. The results showed an increasing trend of the temperature and a decreasing trend of the evaporation, but the increasing trend of precipitation was not significant in the area, and temperature shows significant increase in winter and spring, no changes in autumn and summer in terms of seasonal changes in temperature. The lowest in precipitation and highest in evaporation appeared in 1980s. The winter precipitation was reduced and increased in other seasons since 2000. |
