Floristic diversity and fundamental characteristics of seed plants on Mount Jiangjun, Nanjing
摘要
Abstract
To provide fundamental information and a t heoretical basis for protection and management of plant resources on Mount Jiangjun, floristic diversity and fundamental characteristics of seed plants were determined. Results showed 394 species of seed plants belonging to 95 families and 274 genera. Gymnosperms accounted for two species distributed in two genera and two families. Angiosperms consisted of the other 93 families, 272 genera, and 392 species with monocotyledons accounting for 16 families, 63 genera, and 84 species, and di-cotyledons consisting of the remaining 77 families, 209 genera, and 308 species. Dicotyledons had 110 species of epipetalousb elonging to 20 families and 67 genera, and 189 species of sympetalous belonging to 57 families and 142 genera. The depauperate family (genus) and single species family (genus) occupied a relatively large proportion of the flora;whereas, large families (genera) and less larger families (genera) were absent. Analysis of characterized families, R/T, and floristic compositions of families and genera demonstrated: 1 ) an abundance of floristic compositions, 2) obvious tropical elements influenced by temperate elements, 3) complex geographi-cal components with flora being extensively connected to most floras of the world, and 4 ) existence of few en-demic plants. Thus, phanerophytes and chamaephytes most likely took up a dominant position with therophytes occupying the lowest percentage of the flora. [Ch, 6 tab. 23 ref.]关键词
