中文摘要：

根据树种每个阶段的特征、影响因素,探讨了气候变化驱动下森林生态系统树种迁移过程及相关模型,结果表明,种子生产、扩散载体（主要是风和动物）及扩散阶段性、种子库以及幼苗建成过程中密度、竞争等是树种迁移过程的关键因素。

英文摘要：

Based on the characters and influencing factors of tree species in each stage,the migration process of tree species driven by climate change and its related models were discussed.The results showed that the key factors in the migration process of tree species are as follows： the seeds production,the dispersal vector（mainly are wind and animals）,dispersal periods,seeds bank,density and competition in seeding establishment.
