[Objective] The spatial and temporal variation of soil water under the low impact development measures in Guyuan City of Ningxia Hui Autonomous Region was analyzed, in order to provide scientific reference for the low impact development and construction of sponge city and the construction of the relevant standards and norms for the effective utilization of water resources.[Methods] Three low impact development measures, namely, grassland, aquatic grass ditch and sunken green land were selected, to study the spatial-temporal changes and stability characteristics of soil water storage at different depths. And the changes of soil moisture under different measures of low impact development measures in dry and wet seasons, different rainfall and freeze-thaw conditions were analyzed.[Results] ① The soil water storage capacity of grassland, aquatic grass ditch and sunken green land was 101.96, 27.22 and 97.33 mm respectively all through the year, was 107.37, 29.46 and 101.03 mm respectively in rainy seasons, and was 67.6, 20.66 and 69.34 mm respectively in dry seasons. The variation coefficient of soil water storage under various low impact development measures was between 26.01% and 76.37%, all of which belonged to moderate variation. ② Under rainstorm conditions, the replenishment amount of grassland, aquatic grass ditch and sunken green land was 63.68, 14.84 and 66.49 mm, respectively. Under light rain conditions, the soil replenishment of grassland, aqueduct grass ditch and sunken green land was 3.94, 1.71 and 1.26 mm, respectively. ③ During the freeze-thaw period, the freezing-thawing capacity of grassland, aquatic grass ditch and sunken green land was 111.16, 75.73 and 46.9 mm, respectively. Low temperature and freeze-thaw were mainly concentrated in 0-10 cm soil layer. ④ The annual, rainy, dry, heavy rain and freeze-thaw replenishment of the study area were 1 691.31, 1 766.46, 1 216.31, 1 121.8 and 699.67 m³, respectively.[Conclusion] The potential of soil water recharge under the low-impact development measures is great. And the improvement of structure, filler and vegetation cover of different low impact development measures should be considered to improve the water storage of LID measures.
