摘    要: 分析青海省柴达木盆地1961—2002年气象观测资料得出,年度和四季的气温、降水和地表蒸发的气候变化倾向率均为正值。尤其是近10多年来,柴达木盆地气温升高、降水增多、地表蒸发增加,这些气象要素都有利于气候向暖湿方向发展,但考虑到柴达木盆地的降水总量有限(平均每日降水不足0.3 mm),而地表蒸发总量又与降水总量比较接近,因此,从气象要素的历史变化和季节分布特征看,柴达木盆地的整体环境状况仍处于比较差的阶段。

关 键 词:青海省  柴达木盆地  气候变化

Abstract:The observed meteorological data of Qaidam basin in Qinghai province in 1961\_2002 are analyzed. The result shows that the changing tendency rate of precipitation and surface evaporation as well as annual and seasonal temperature is positive. Especially in last decade, the air temperature rose, the surface evaporation and precipitation increased, these were favorable for the climate developed toward warm and wet. But due to the limited rainfall (daily average rainfall less than 0\^3 mm) and its approximation with surface evaporation amount, the overall environment state of Qaidam basin is still under relatively inferior stage viewed from the historical change of meteorological factors and seasonal distribution characteristics.
Keywords:Qinghai province  Qaidam basin  climatic change
