摘  要：
以干旱风沙区林药间作恢复措施为研究对象,研究了通过不同密度柠条林内种植甘草的生态恢复措施对土壤环境的影响。结果表明:8 m,6 m柠条带间的土壤含水量明显高于自然恢复地,3 m带间土壤含水量低于自然恢复地;土壤容重以6 m带距和8 m带距的较低,自然恢复地最高;总孔隙度以6 m带距内的最高,其他处理措施差异性不显著;土壤速效氮、速效磷表现出以自然恢复地较高;物种多样性为8 m带距内的人工甘草恢复区>6m带距内的人工甘草恢复区>野生甘草自然恢复区>3 m带距内的人工甘草恢复区;适宜的林药间作恢复措施一定程度上增加了物种数和植被的盖度,但是人工柠条林的密度过大,反而引起植被盖度的下降及单个植物优势度的增加。

摘  要：
Through planting licorice in different density caragana forest to soil environment respond,the restoration measure of forest plant-medicine intercropping was studied in arid desert,the result showed:the water content in 8 m,6 m of caragana strap is obviously higher than the natural recovery,the water content in 3 m of Caragana strap is less than the natural recovery,soil bulk in 6m and 8m strap is lower,the natural recovery is the highest,total porosity in 6 m strap is the highest,the difference of other processing measures isn't prominent,soil readily available nitrogen,soil readily available phosphate,demonstrates relatively tally with the natural recovery;Species variety demonstrates artificial licorice in 8 m strap> artificial licorice in 6m strap > wild licorice in natural recovery area > artificial licorice in 3 m strap;The restoration models of suitable forest medicine intercropping have increased the species number and vegetation covering degree,to some extent,but the exorbitant density of artificial caragana forest would cause the decline of the vegetation overlay degree and the increase of single plant advantage degree.
