| Abstract: | There are 806 species seed plants in Pangquangou National Nature Reserve area,belong to 81 families,344 genera,among which wild species has 786 species;and gymnosperms have 2 families,6 genera,9 species,which respectively account 20 percentage,15percentage,4.7 percentage of the same countrywide;and angiosperms have 79 families,338 genera,797 species,which respectively account 27percentage,11percentage,2.97 percentage of the same countrywide.In the family distributions,world distribution family is dominate and make 44.4 percentage of the total families of seed plants,and temperate distribution is second.Among the genera distribution,temperate elements is dominate,north temperate distribution types account 50 percentage of non-world genera of seed flora in this area,which indicates this area is obvious temperate characteristics of flora. |
