Separating Vegetation Greening and Climate Change Controls on Evapotranspiration trend over the Loess Plateau

Abstract Evapotranspiration (ET) is a key ecological process connecting the soil-vegetation-atmosphere system, and its changes seriously affects the regional distribution of available water resources, especially in the arid and semiarid regions. With the Grain-for-Green project implemented in the Lo...
