中文摘要	沙棘及其混交林减少径流泥沙的作用突出，但结构和混交模式不同所发挥的水保作用大小不同。沙棘林生长季各月消耗利用水分的强度不同。在整个生长季，5月末0 ～ 500cm土层平均含水率最低，为5.1%；10月末最高，达8.8%。沙棘林对土水分的利用强度受林龄影响，8龄沙棘林年消耗土壤贮水231.2mm，应进行平茬。平茬后第3年末，土壤水分恢复深厚达160cm，含水率为10.3% ～ 14.6%。沙棘林具有消减坡位对土壤水分影响的作用。沙棘及其混交林对土壤水分的利用强度相似，林地存在土壤干层现象。
英文摘要	There is a remarkable function on decreasing runoff and sediment in seabuckthorn and its mixed stands, but the effects on soil-and water conservation are different due to different structure and patterns of seabuckthorn and its mixed stands. The intensity of soil water use by seabuckthorn forest was different along with the month in grow-ing season. In growing season, soil moisture in 0 - 500 cm layer was 5.1%, the lowest in the end of May and 8. 8% , the highest in the end of October. This intensity was also different with forest age. 8 ages seabuckthorn forest consumed 231. 2mm of soil stored water in 0 ~ 500cm layer annually, and soil moisture was 5. 6% . Therefore, it should be cut for increasing soil moisture. In end of the third year after cutting, soil moisture in 0 ~ 160cm layer could recover, and the value would be!0.3%~14.6%. Seabuckthorn forest could reduce the ef-fect of slope location on soil moisture. Seabuckthorn and its mixed stands have similar intensity of soil water use, and there was a soil dry layer phenomenon in their stands.
