Artificial Regeneration under Pinus sylvestris var. mongolica Plantation on Sandy Land

Pinus sylvestris var.mongolica plantations were regenerated on sandy land after gradually cutting,with the canopy being less than 0.4.Growth of each species was observed after 10 years and the forest soil were investigated.Result shows that:the use of such a way that artificial regeneration under canopy of pure forest of Pinus sylvestris var.mongolica tree species can be changed into a multi-storied complex;Acer mono other 4 species can be regenerated as the main species cultivated under canopy trees;crown can be gradually improved under the artificial regeneration soil,delaying soil recession of Pinus sylvestris var.mongolica plantation.
