Abstract: Sustainable forest management is directly related to silvicultual activities.Achievements of afforestation in China are world famous,while,with the development of afforestation,some worrying events have turned out.For example,the monoculture of pure stands has caused gradual decrease of stand growth,and led to the loss of biological diversity,disequilibrium of forest ecosystem and the occurrence of disasters.As a valuable conifer tree species,Mongolian pine (Pinus sylvestris var.mongolica) has become a major tree species and been broadly introduced to sandy land in the arid and semi-arid area of northern,northwestern and northeastern China.However,the plantations of Mongolian pine on sandy land have declined in different degrees since early 1990s.In order to achieve sustainable forest management,it is important and significant to review and discuss the silvicultual activities of Mongolian pine plantations.Based on a wide range of literature collection on Mongolian pine,the research development on silviculture of Mongolian pine were summarized,which included the reason of low survival rate of afforestation and the techniques to improve it,the production of seed,the management of stand density,cultivation pattern,thinning and regeneration etc.Some problems to be solved were put forward and the suggestions were given.
