英文摘要	The impacts of land use/cover changes (LUCCs) on groundwater resources are a global issue. The Shiyang River Basin of China is a typical, ecologically fragile area. Focusing on the Wuwei sub-basin of the central plain, this study analyzed typical remote sensing image data for 17 specific dates since 1970. Before the Comprehensive Treatment Program in 2007, the area of natural oases decreased at a rate of 16.25 km(2)/year, while the area of farmland expanded at a rate of 13.85 km(2)/year. The farmland expansion preferentially occurred in low-vegetation-coverage oases, where the groundwater depth increased from 4 to 20 m. The consumption of groundwater increased from 7319.5 x 10(4) m(3)/year to 12,943.2 x 10(4) m(3)/year. During the period 2008-2018, the areas of both the natural oases and farmland decreased at rates of 2.57 km(2)/year and 8.99 km(2)/year, respectively. The groundwater level rose significantly in the south and west, as well as near the main river channel. Groundwater consumption has been restored to 7270.4 x 10(4) m(3)/year. Only 0.12 km(2) of every 1.17 km(2) of the original natural oases were restored through the natural farmland-natural oases conversion process. Groundwater depth increased significantly with the continuous expansion of farmland. Since the farmland area was effectively controlled, the trend of groundwater-level decline was significantly improved. These findings provide scientific support for the ecological restoration and reconstruction of oases, as well as an efficient and balanced development of river basin water resources.
