Abstract
In order to study the floristic characteristics of spermatophytes, floristic composition of spermatophytes and characteristics of monotypic （oligotypic） genera in Longdi Protection Zone were analyzed. The results showed that ：wild spermatophytes flora in the protection zone is made up of 2 174 species in 859 genera of 188 families, among which, gymnosperms take 21 species in 15 genera of 8 families. Monotypic （oligotypic） genera of flora is made up of 209 species in 183 genera of 83 families ,taking 21.30% of the whole flora in this area. Mouotypic （oligotypic） genera can not only display its nature of relict and endemism, and the vegetation composition characteristics of subtropical evergreen broad-leaf forests, but also reveal the stage and process of plants evolution. There are some differences between monotypic （oligotypic） genera and the whole floristic genera in composition proportion of growth form and life-form spectrum. The distribution types of the floristic genera are mainly tropical components while monotypic （oligotypic） genera are mainly temperate components. Monotypic （oligotypic）genera have an advantage in Chinese emdemic genera, endemic genera to eastern asia and asian endemic genera in tropical zone.关键词
