[Objective] In order to investigate the soil moisture characteristics of four vegetation restoration measures under different spatial locations of Hangjinqi photovoltaic power station in the Kubuzi Desert, and to provide a scientific basis for the rational configuration and management of sand-fixing vegetation in photovoltaic power stations.. [Methodology] The ring knife method was used to determine the soil water content at 0-100 cm depth under four different vegetation types between and under the plates at different locations (windward side, array belly, leeward side) in the study area, and to analyze the characteristics of vertical distribution of soil moisture, variability, soil water storage and soil water storage deficit. [Results] (1) All four vegetation restoration measures increased the soil water content, with the average water content of Artemisia ordosica Krasch (2.09%) > Leymus chinensis (2.089%) > Glycyrrhiza uralensis Fisch (2.06%) > Hedysarum scoparium (1.98%) > Bare sand (1.34%); the spatial distribution shows the pattern of windward side＜leeward side＜array belly and interplate＜subplate. The variability of soil moisture was higher for the Glycyrrhiza uralensis Fisch and Leymus chinensis vegetation restoration measures than for the Artemisia ordosica Krasch and Hedysarum scoparium measures. (2) The change range of soil water storage in 0-100cm depth of different vegetation restoration measures is between 16.72-51.55mm, and the change trend of soil water storage is similar to the change trend of soil water content. (3) The soil water storage deficit of different vegetation restoration measures in the photovoltaic power station is as follows: bare sand (78.81%) > Hedysarum scoparium (69.00%) > Leymus chinensis (68.95%) > Artemisia ordosica Krasch (67.23%) > Glycyrrhiza uralensis Fisch (63.11%), and decreases with increasing soil depth, and the spatial distribution is inter-slab > sub-slab, windward side > leeward side > in the belly of the array. [Conclusion] The four vegetation restoration measures in the study area efficiently increased the soil water content in all parts of the soil, theArtemisia ordosica Krasch and the Hedysarum scopariumk were higher than the other measures in the range of 0-30 cm with lower coefficients of variation, and the soil water content, water storage, and water storage deficit of the Leymus chinensis and the Glycyrrhiza uralensis Fisch were better than those of the other measures at depths of less than 30 cm. Therefore, during the operation and maintenance period, planting Artemisia ordosica Krasch and Hedysarum scoparium on the windward side of the serious wind erosion can more effectively alleviate the wind erosion, and planting Leymus chinensis and Glycyrrhiza uralensis Fisch and other cash crops in the hinterland and other areas of the array which are less seriously affected by the wind erosion, in order to cope with the problem of serious secondary killings and to achieve the purpose of industrial income generation.
