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.关键词
