英文摘要	Partitioning evapotranspiration (ET) into soil evaporation (Ea) and plant transpiration (Tr) is important to understand response of ecosystem water balance to climate warming. A field experiment was conducted to investigate the effect of additional infrared radiation as a simulation of climate warming (W1: 130Wm-2and W2: 150Wm-2) on ET, Ea, Tr, and soil moisture in an alpine meadow in the Qinghai-Tibet plateau (QTP). ET was calculated by using an energy balance model and a soil moisture correction function. Eain warm-rainy season was estimated by a multiple linear regression with latent heat, soil moisture in 0-10cm layer and soil temperature in 20cm depth as independent variables. Trwas quantified as the difference between ET and Ea. Results showed that annual ET increased by 92mm and 89mm, annual Eaincreased by 29.12mm and 33.37mm, and annual Trincreased by 63.53mm and 55.81mm in W1 and W2 treatments, respectively. The results suggest that Trstimulation accounts for most of the ET change and is the major reason for the soil surface layer drying in alpine meadow ecosystem on the QTP. 2015 Elsevier B.V.
