This dataset comprises soil moisture and related hydrological data collected from 2005 to 2022 in the desert–oasis farmland ecosystem in the middlestream of the Heihe River Basin. The observation plot is located within the main site area of the Linze Inland River Basin Research Station (center coordinates: 100°07′51″E, 39°20′56.5″N, elevation: 1382 m), situated in a transitional zone between desert and oasis. The soil type is aeolian sandy soil, specifically classified as irrigated cultivated aeolian sandy soil (a sub-type). Groundwater depth ranges from 4 to 6 meters below the surface. The plot is rectangular, covering an area of 38 m × 58 m, and is managed under a wheat–maize rotation system with irrigation primarily sourced from groundwater, applied 7 to 10 times annually. Key monitored parameters include soil water content, surface water and groundwater quality, groundwater table depth, soil moisture constants, rainwater quality, and irrigation volume.", "ds_time_res": "日", "ds_acq_place": "Linze County, Zhangye City, Gansu Province", "ds_space_res": "", "ds_projection": "", "ds_process_way": "
