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.
