英文摘要	Suitable groundwater level is an important foundation for the stability of the ecological environment, and the healthy development of the social economy, in the arid area of Northwest China. The Manas River Basin is a typical oasis in an arid area, where the problems of salinization and desertification are prominent. By analyzing the variation characteristics of groundwater in the study area from 2013 to 2019 combined with remote sensing technology-according to the theory of capillary water rise and phreatic evaporation-a mathematical calculation model of the ecological threshold is established to determine the ecological groundwater level. The results show that (1) the groundwater level in the study area fluctuates by 0.2-18 m throughout the year, and the variation of groundwater drawdown is 5-35 m from 2013 to 2019; (2) the upper threshold of the ecological groundwater level is 0.82-4.05 m and the lower threshold is 3.35-10.23 m; (3) the ecological water shortage area in the study area is 9755.36 km(2), and the groundwater ecological deficit is 105.741 x 10(8) m(3). This study can provide a theoretical basis for the determination of the ecological groundwater level, the optimal allocation of water resources, and ecological environment management in the arid area of Northwest China.
