Research on Flora of Seed Plants in Miaodao Archipelago of Shandong
摘要
Abstract
There are now 504 species of seed plants in Miaodao archipelago, belonging to 81 families and 288 genera, two new variants are discovered, and 19 species in two genera of them are newly recorded in Shandong Province. According to the analysis of the seed plant genera and species, the flora of seed plants in this area has typical temperate features. Of all the genera, the temperate distributed genera accounts for 56.6% , while the tropical distributed genera accounts for 33.2% , there are no typical tropical species and genera. Both the North and South plants can be found in Miaodao archipelago, where there are complex floristic elements and rich costal plants. Only three genera are endemic to China, and there is no regional endemic genus. The flora of seeds plants in Miaodao archipelago is compared with that of neighboring areas, indicating that the seeds plant genera in Miaodao show high similarity with that in Hebei and Iiaoning Province, but presents decreasing similarity with that in Anhui, Jiangsu and Beijing. The composition uf Raunkiaer' s life-form is arranged as Hemicrytophytes(27.4% ) > Ghanero-phytes(25.8%) >Therophytes(25.0% ) > Cryptophytes( 19. 3% ) > Chamaephytes(2.6% ).关键词
