Hydroclimatic Gradients Shape Differential Responses of Vegetation Photosynthesis in Croplands and Typical Natural Vegetation to Atmospheric Evaporative Demand and Soil Moisture
Vegetation photosynthesis is jointly regulated by precipitation supply, atmospheric water demand, and vertically stratified soil moisture, but their relative roles across vegetation types and hydroclimatic backgrounds remain unclear. Using monthly satellite solar-induced chlorophyll fluorescence (SIF), ERA5-Land hydroc...
