鄂东南幕阜山区共种子植物１８３科７４１属１６５３种。以属的分析为主，结合科的分析，认为本地区种子植物区系为温带性质。本地区温带分布型属占总属数（剔除世界分布属）的５３１３％，热带分布型属占总属数的４２４５％，缺乏典型的热带科属。从植物区系现状和历史分析中，论证了本区系白垩纪—第三纪古热带起源的历史背景。确认本地区主体上属于中国—日本森林植物区系的华东地区，但富含华中区系成分，具有浓厚的华中区系色彩。本地区南北和东西植物交汇，具有复杂区系成分。论证了鄂西南武陵山—幕阜山脉一线可能是西南成分向东迁移的通道之一。本地区特有现象不明显，共有中国特有...

This paper has recorded 1653 species of 741 genera among 183 families of spermatophyte plants in the Mufu Range area, SE. Hubei province, which is situated between 113°36′～115°30′E, 29°02′～31°15′N.

Although this flora belongs to the East China region of the Sino-Japanese forestry subkingdom accoring to C. Y. Wu (1979), it is also abundant in the floristic elements of SW. Chi...
