| 摘 要： | 通过对贡嘎山自然保护区高等植物的野外调查数据整理和已有资料的统计分析,结果表明:1)贡嘎山自然保护区有高等植物151科688属2 472种(含种下单位,下同),种子植物有120科631属2 323种。保护区植物科、属、种组成丰富,被子植物占有明显优势,科、属、种分别占总数的77%、90%、93%;2)保护区地质历史悠久,生态环境复杂多样,单种属和少种属数量较多,植物区系起源古老。北温带分布类型、东亚分布类型及泛热带分布类型占据着不同的地域和海拔,并彼此交汇渗透,使该地区植物区系组成复杂;3)保护区各类温带性质的区系成分共计237属,热带性质的区系成分共计162属,表明该地区植物区系具有明显的温带性质;4)保护区东亚分布类型明显高于全国水平,结合保护区所处的地理环境以及与其它植物区系间的关系,表明保护区是某些植物分布的过渡地带,特别是东亚分布类型具有明显的过渡性。

| Abstract: | According to the collation of the field survey data of the higher plants in Gongga Mountain Nature Reserve and the statistical analysis of existing data, the results have shown that （ 1 ） there are 151 families ,688 genera and 2 472 species of higher plants（ including the planted unit, the same below）, and 120 families ,631 genera,2 323 species of seed plants in Gongga Mountain Nature Reserve. The composi- tion of the plant families, genera, species in the protected area is very rich, angiosperms occupy an obvious advantage, their families, genera, species account for 77 % ~90% and 93 % respectively ; （2） The protected area has a long geological history and ecological complexity, diversity, and has a larger number of small species and single species. Besides, the flora is of ancient origin. The distribution types of the North tem- perate zone, the East Asia and the Pan-tropical occupy different regions and altitudes, and they intersect and penetrate each other,which makes the region＇s flora complex;（3）All kinds of temperate flora in the protected area count up to 237 genera, tropical floras sum 162 genera ,which show that the flora of this re- gion has a significant temperate nature ; （4） East Asian distribution types of the protected area significantly are higher than the national level. Combined with the geographical location of the protected area and the relationship between the other floras, it is indicated that the protected area is the transition zone of the some plants＇ distribution, particularly the East Asian distribution type has a significant transitivity. |
