| 摘 要： | 在与天然油松群落比较的基础上,分析了北京市王家堡飞播造林基地油松群落种子植物区系特征。结果表明,飞播油松群落现有种子植物36科75属92种,略高于天然油松林。单种科、属增多,优势科有别于天然油松林。飞播油松群落种子植物科分布型仅有4种,属区系成分相对复杂。与天然油松群落相似,飞播油松群落种子植物区系明显具有温带性质,北温带分布的属最多,旧世界温带分布类型的属次之。飞播油松群落区系特征与其群落特征一样表现出特殊的性质。

| Abstract: | In comparison with the communities of natural piuns tabulaeformis,the floristic characteristics of seed plants of the communities of Pinus tabulaeformis forest sown by plane were analyzed in this paper.The results showed that 92 species of seed plants in 75 genera covering 36 families existed in the community,beyond the natural community slightly.Compared with the natural forest,the number of both genera and families including single species were increased sharply as well as the dominant families were distinct and different in the community.There were only four distributional types of families and 13 of genera richer than the natural forest.Also,its flora,alike the natural forest,showed an obvious temperate zone charac- ter with abundant the North temperate followed by the old world temperate component.It was concluded that its flora char- acteristics as same with the traits of the community were different from the natural forest. |
