There are few studies on the relationship between soil moisture content and soil moisture factors and site factors, especially the investigation of different shrubs in the western Loess Plateau. This is the main problem to be solved in the ecological recovery of the western Loess Plateau. Therefore, studies on the distribution of soil moisture in artificial shrub lands on the Loess Plateau in the West can help select the most suitable afforestation tree species, determine appropriate afforestation techniques, and provide a reference area for vegetation restoration and ecological construction.

The analysis of variance and correlation between the soil profile data and the soil moisture data in the study area were performed by a soil moisture meter to obtain the effect of different terrain factors on the distribution of soil moisture. In order to more accurately represent soil moisture distribution, soil moisture reserves were used in analysis of variance and correlation analysis.
In the same aspect, the evapotranspiration of soil moisture is basically the same, and the main factor that causes the change of soil moisture is the transpiration intensity of the plant. The soil moisture measuring instrument was used to measure the difference of soil water reserves under different shrubs. The major soil water reserves were Caragana in the desert, Caragana kanbonensis and Caragana, followed by Red Sand, Overlord, Nitraria tangutorum, Haloxylon ammodendron and Bollard. The results showed that the transpiration intensity of plants in Caragana sphaerocarpa, Caragana mongolica, and Caragana was lower than that of other shrubs and water consumption was less.
The related research of soil moisture measuring instrument shows that in order to relieve the unfavorable conditions in the noon, the root system continuously absorbs water from the soil, reduces the surface temperature of the plant through strong transpiration, and obtains resistance to high temperature and water stress through water loss on the surface of the leaf. Ability to adapt to arid environment. Compared with other shrubs, Haloxylon ammodendron has the highest soil moisture reserves and Caragana is the lowest. This indicated that under strong light, the transpiration of Caragana korshinskii was enhanced and the water consumption of plants increased.
