A Preliminary Floristic Study on the Seed Plants from Liziping Reserve in Sichuan

There are 134 families,715 genera,1 795 species and 153 varieties of seed plants flora in Liziping Reserve of Sichuan Province,including 7 families 14 genera 31 species Gymnosperms.About 62 families which with less than 10 species about 46.27% of total families in the region are the most abundant.Although the families with more than 20 species(including 28 families 1 319 species) are the main composition,they are the most important ingredient in the flora of Liziping Reserve.In the level of genus,show that about the genera which with less than 10 species are the most abundant in the region.The richness of relict and endemic species shows that the seed plants in the region is old and primitive.On the other hand the richness of varieties shows that the seed plant has high polarization in the region.The areal-types of families are mainly tropical,but those of genera reflect a typical temperate.
