| Abstract: | Objective] The structure feature of low function’s pinus tabulaeformis plantation was explored.Method]With the help of sample plot survey to inefficient Pinus tabulaeformis planted forest in the low mountain of Beijing,the Pinus tabulaeformis’tree species composition,tree height structure and diameter structure were analyzed.Result]Over crowed,poor stand,human disturbance and no matching species with the site were the main reasons to lead to the forest inefficient.Conclusion] According to the several main cause of low efficiency,the suggestions for the process of forest culture and management were proposed. |
