Three groundwater burial depth gradients of 2.5 m, 4.5 m and 11.0 m were set up, and the Hedley phosphorus classification method was used to measure soil resin phosphorus (Resin-P) and sodium bicarbonate inorganic phosphorus (NaHCO-Pi), sodium bicarbonate organic phosphorus (NaHCO-Po), sodium hydroxide inorganic phosphorus (NaOH-Pi), sodium hydroxide organic phosphorus (NaOH-Po), dilute phosphorus hydrochloride (HCl-Pi), concentrated inorganic phosphorus hydrochloride There are nine soil phosphorus components including (Conc.HCl-Pi), concentrated organic phosphorus hydrochloride (Conc.HCl-Po) and residual phosphorus (Residual-P), and also include soil organic carbon, inorganic nitrogen, nitrate nitrogen, ammonium nitrogen, available phosphorus, available potassium, soil water content, pH, and microbial biomass carbon, nitrogen, phosphorus and other indicators. This dataset can be used to analyze the impact of groundwater changes on soil phosphorus cycles and nutrient restriction mechanisms in extremely arid ecosystems.This dataset includes soil phosphorus components and related soil physical and chemical properties at three groundwater depths (2.5m, 4.5m and 11.0m) in the arid desert ecosystem on the southern edge of the Taklimakan Desert in Xinjiang, China. Soil phosphorus components were determined using the Hedley phosphorus composition method, including resin-P, sodium phosphorus bicarbonate (NaHCO3-Pi), sodium phosphorus bicarbonate (NaHCO3-Po), sodium phosphorus hydroxide (NaOH-Pi), sodium phosphorus hydroxide (NaOH-Po), phosphorus hydrochloride (HCl-Pi), concentrated phosphorus hydrochloride (Conc.IHCI-Pi), concentrated phosphorus hydrochloride (Conc.HCI-Po) and residual phosphorus (Residual-P). Other measurement indicators include soil organic carbon, inorg
