主　　题：evapotranspiration control factor typical underlying surfaces Qinghai-Tibetan Plateau 

摘      要：To reveal the characteristics of evapotranspiration and environmental control factors of typical underlying surfaces(alpine wetland and alpine meadow)on the Qinghai-Tibetan Plateau,a comprehensive study was performed via in situ observations and remote sensing data in the growing season and non-growing *** was positively correlated with precipitation,the decoupling coefficient,and the enhanced vegetation index,but was energy-limited and mainly controlled by the vapor pressure deficit and solar radiation at an annual scale and growing season scale,*** with the non-growing season,monthly evapotranspiration,equilibrium evaporation,and decoupling coefficient were greater in the growing season due to lower vegetation resistance and considerable ***,these factors were restricted in the alpine *** decoupling factor was more sensitive to changes of conductance in the alpine *** study is of great significance for understanding hydro-meteorological processes on the Qinghai-Tibetan Plateau.
