- Abstract
Surface evapotranspiration is the process of moisture exchange in the atmosphere, biosphere and hydrosphere. Accurate estimation of evapotranspiration has important application value for regional water resources assessment, crop water requirement and production management, agricultural drought monitoring and ecological environmental issues. In this study, eight plots were selected in the upper, middle and lower reaches of the Xilin River Basin, including the main plant communities with severe degradation, slight degradation, and no degradation in the basin. The soil column weighing method was used to measure the daily evapotranspiration in each sample plot. Based on the meteorological, soil, and vegetation data measured over the same period, a mathematical relationship model between the evapotranspiration and meteorological factors, soil moisture, and community vegetation characteristics was established. The model is well-fitted and validated by randomly selected 20 groups of data. Within the allowable error range, the model meets the accuracy requirements and can be used for model estimation of vegetation communities evapotranspiration in Xilin River Basin.
