For instance, in corn farmland, the vegetation transpiration components of ET can increase directly with increased GPP and the soil evaporation components of ET can decrease associated with increased GPP [1]. Against the background of human activities and global warming, one of the prerequisites for rational carbon-water management is to have an accurate measure of the ET and GPP characteristics of a terrestrial ecosystem. This understanding plays an essential role in the sustainable development of the regional ecological environment and regional water resource management. Over nearly a decade, numerous ET measurements for water consumption and GPP measurements for biomass production at single station and global (regional) scales have been derived from remote sensing data with ET models, such as the Surface Energy Balance System (SEBS) [2; 3], the two-source energy balance (TSEB) model [4; 5], the Penman-Monteith (P-M) [6] and Priestley-Taylor (P-T) equations [7; 8], and the Global Land Evaporation Amsterdam Model (GLEAM) [9] and GPP models [10; 11]. These have been used to compute water-use efficiency (WUE) for water-resource assessment using GPP divided by ET, which is a key indicator linking biological processes between carbon uptake and water consumption [12; 13; 14; 15]. According to the main research line at the single station and regional (global) scales with different spatiotemporal resolutions, the existing research has the following features.
