摘要:
为以沙棘为主的人工植被建设评价提供依据，在黄土丘陵半干旱区选择4，8，12，15 a沙棘林地进行土壤水分、养分测定，结果表明：在测定年份不同林龄沙棘林地0-600 cm土层含水量差异较小，150-400 cm土层存在明显干层，平均含水量仅为5.48%，400-600 cm土层含水量有明显随林龄增加而减小的规律；不同林龄沙棘林地土壤养分均富集在0-10 cm土层，养分含量随着土层深度增加明显减小，林龄对土壤养分含量具有一定影响，有随林龄增加养分含量增加的趋势。
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.
