Abstract
Based on the research on the growth situation of Pinus sylvestris var.mongolica Litv.at different altitude in Bashang district,Zhangjiakou,the results show that with the altitude′s rising,the growth of height and rootstock of Pinus sylvestris var.mongolica Litv.is restricted and the cold mortality increase.This is a main leading factor to restrict the introduction of Pinus sylvestris var.mongolica Litv.in Bashang district,Zhangjiakou.
