英文摘要Partitioning evapotranspiration (ET) into soil evaporation ((Ea)) and plant transpiration (T-r) 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 (WI: 130 W m(-2) and W2: 150 W m(-2)) on ET, E-a, T-r, 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. E-a in warm-rainy season was estimated by a multiple linear regression with latent heat, soil moisture in 0-10 cm layer and soil temperature in 20 cm depth as independent variables. T-r was quantified as the difference between ET and E-a. Results showed that annual ET increased by 92 mm and 89 mm, annual E-a increased by 29.12 mm and 33.37 mm, and annual T-r increased by 63.53 mm and 55.81 mm in W1 and W2 treatments, respectively. The results suggest that T-r stimulation 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. (C) 2015 Elsevier B.V.
