| 摘 要： | From 1981 to 2010,the effects of climate change on evapotranspiration of the alpine ecosystem and the regional difference of effects in the Tibetan Plateau(TP) were studied based on the Lund-Potsdam-Jena dynamic vegetation model and data from 80 meteorological stations.Changes in actual evapotranspiration(AET) and water balance in TP were analyzed.Over the last 30 years,climate change in TP was characterized by significantly increased temperature,slightly increased precipitation,and decreased potential evapotranspiration(PET),which was significant before 2000.AET exhibited increasing trends in most parts of TP.The difference between precipitation and AET decreased in the southeastern plateau and increased in the northwestern plateau.A decrease in atmospheric water demand will lead to a decreased trend in AET.However,AET in most regions increased because of increased precipitation.Increased precipitation was observed in 86% of the areas with increased AET,whereas decreased precipitation was observed in 73% of the areas with decreased AET.

| Abstract: | From 1981 to 2010, the effects of climate change on evapotranspiration of the alpine ecosystem and the regional difference of effects in the Tibetan Plateau (TP) were studied based on the Lund-Potsdam-Jena dynamic vegetation model and data from 80 meteorological stations. Changes in actual evapotranspiration (AET) and water balance in TP were analyzed. Over the last 30 years, climate change in TP was characterized by significantly increased temperature, slightly increased precipitation, and decreased potential evapotranspiration (PET), which was significant before 2000. AET exhibited increasing trends in most parts of TP. The difference between precipitation and AET decreased in the southeastern plateau and increased in the northwestern plateau. A decrease in atmospheric water demand will lead to a decreased trend in AET. However, AET in most regions increased because of increased precipitation. Increased precipitation was observed in 86% of the areas with increased AET, whereas decreased precipitation was observed in 73% of the areas with decreased AET. |
