| 摘 要： | 云南省大中山自然保护区有种子植物749种,隶属于137科396属。区系成分中,世界分布33属,占全部总属数的8.33%;热带分布206属,占除世界分布属以外的56.75%(下同),温带分布148属,占40.77%,中国特有9属,占2.48%。该地区植物种类丰富,种子植物区系起源古老,地理成分复杂,具有明显的亚热带特性。从区系成分和植物类群多样性所占比例上看,是一个需要重点保护的区域。

| Abstract: | There are 749 species of seed plants belonging to 396 genera and 137 families in Dazhongshan Nature Reserve of Yunnan Province. In this flora,the amount of the cosmopolitan genera is 33,being 8.33% of the total genera. The amount of tropical genera is 206,being 56.75% of the total genera (excluding those cosmopolitan genera,the same below). The amount of temperate genera is 148,being 40.77% of the total genera. The amount of endemic in China genera is 9,being 2.48% of the total genera. The composition of this flora is complicated. The floristic characteristic of seed plants of the region is subtropical in nature,and it is between the tropical flora and temperate flora. So the region is worth of being protected as its complex floristic geographic elements and plants population diversity. |
