Abstract:: In order to provide the basis of assessing the benefits of seabuckthorn as main shrub species artificial vegetion,four seabuckthorn stands afforested 4,8,12,15 years respectively are chosen for soil moisture and soil nutrient measurements in semi-arid loess hilly region.Results indicate that there is little discrepancy of soil moisture among the four stands in soil profile of 0-600 cm because of less annual precipitation in the measured year.There is an obvious dry-soil layer in soil profile of 150-400 cm and average soil moisture is only 5.48%.There is a visible regulation that soil moisture decreased gradually with the increase of seabuckthorn shrub ages in 400-600 cm soil layer.Much more soil nutrient enriched in the layer of 0-10 cm soil in the measured stands,soil nutrient content decreases gradually with the increase of soil depth.Seabuckthorn shrub age has definite effect on the change of soil nutrient content in the stands,which shows a trend of soil nutrient content increasing slowly with seabuckthorn age increasing.
