Spatiotemporal Variation of Actual Evapotranspiration and Its Relationship with Precipitation in Northern China under Global Warming
The analysis of actual evapotranspiration (ETa) changes is of great significance for the utilization and allocation of water resources.In Extension this study, ETa variability in northern China (aridity index R = 0.682), whereas the increase in precipitation is insignificant (p = 0.151).Spatially, the long-term trend of ETa is also not completely c
