摘　　要：宝天曼自然保护区青檀林可分为乔木层、灌木层和草本层 ,共有植物 171种 ,分属于 6 8科 ,131属 ,以单叶、非全缘叶、草质叶为主要特征 .在青檀林中 ,各个层次优势种明显 ,青檀Pteroceltistatarinowii是乔木层的优势种 ,其重要值较大 ;青檀林物种多样性指数在 3 30～ 4 4 9之间 ,生态优势度在 0 0 5～ 0 14之间 ,均匀度在 0 5 6～ 0 77之间 ,种间相遇概率在 0 87～0 93之间 。The Pteroceltis tatarinowii forest of Baotianman national nature reserve can be divided into arbor gradation,bush gradation and herb gradation,there are 171 species of plants belonging to 131 genus and 68 families,respectively.Most plants have simple leaves,partial edge leaves and grass quality leaves.In Pteroceltis tatarinowii forest,the superior species of every gradation are evident, Pteroceltis tatarinowii ,the superior species of arbor gradation,has a bigger value of importance. The species diversity index ranges from 3.30 to 4.49,the ecological superior degree ranges from 0.05 to 0.14,the even degree ranges from 0.56 to 0.77,the interspecies meeting frequency ranges from 0.87 to 0.93,the changes of vertical zone character of species diversity index and ecological superior degree are evident.
