In order to solve the reality of low growth rate of Quercus,and poor growth of Pinus tabu-lae formis mixed Quercus in forest areas,seedling cultivation and afforestation experiments of Pinus koraiensis in Qiaoshan forest area were explored the possibility of introducing and developing Pinus koraiensis in Qiaoshan forest area,a kind of theoretical basis for improving the biodiversity in forest area.The experimental results showed that the three-year preservation rate of seedlings cultivation and afforestation under the forest canopy is 85.2％.Therefore,it is feasible to introduce Pinus ko-raiensis for afforestation under the forest canopy in the Qiaoshan forest area.
