This data is the vegetation water use efficiency data for the Shiyang River Basin from 2001 to 2020, with a spatial resolution of 1 kilometer. The vegetation water use efficiency defined in this data product is the ratio between the total primary productivity of vegetation and the evapotranspiration (unit: grams of carbon/kilograms of water/year), which characterizes the trade-off between photosynthesis carbon assimilation and water consumption of vegetation, and reflects the ecosystem service capacity of the vegetation area.
Vegetation evapotranspiration is derived from the “Shiyang River Basin 1-kilometer resolution total annual surface evapotranspiration dataset (2001-2020)”, which is estimated by the ETMonitor model driven by multi-source remote sensing data, etc.; Vegetation TPP is estimated by taking soil water stress into account, and the total primary productivity of vegetation is estimated by taking soil water stress into account, and the total primary productivity of vegetation is estimated by taking soil water stress into account. This data product was estimated by the ETMonitor model driven by multi-source remote sensing data, etc.; the total primary productivity of vegetation was estimated by the EF-LUE model, which is an improved model of light energy utilization rate after considering soil moisture stress. This data product is expressed in grams of carbon/kg of water/year with a conversion factor of 0.01.
