Sensitivity and attribution analysis of vegetation changes on evapotranspiration with the Budyko framework in the Baiyangdian catchment, China

Due to its role in intercepting and evaporating water, vegetation has a great influence on the catchment hydrological process, and an increased quantitative understanding of how vegetation changes affect the terrestrial water cycle is of considerable interest for a range of spatial scales. In this s...
