Pinus sylvestris var.mongolica is an important afforestation tree species in western Liaoning.In order to construct the prediction model of the taper of Pinus sylvestris var.mongolica in sandy land,the taper equation was constructed based on the data of 42 parse trees of Pinus sylvestris var.mongolica in Zhangwu County.Finally,it is concluded that the modified Kozak2004 equation was the optimal taper equation model of Pinus sylvestris var,mon-golica in Zhangwu area.
