Flora of seed plants in Pingtan Island, Fujian and effects of exotic plants
摘要
Abstract
The flora were investigated and analyzed in Pingtan Island, Fujian Province.According to primarily statistics, there are 541 species of seed plants belonging to 369 genera of 127 families, including 330 species of native plants in 234 genera of 91 families and 211 species of exotic plants in 160 genera of 79 families.Compared to nearby mainland and coastal islands in China, the major characteristics of Pingtan Island flora were summarized as follows: Firstly, island plants species were poorer than continential plants.The quantity of single-species family was more than that of dominant families.The flora of species and genera in Pingtan Island was similar to that in Jiufeng Mountain and Chongming Island.The cluster analysis showed that the distribution type of genera flora in Pingtan Island was similar to Huboliao National Nature Reserve and Dajinshan Island.Secondly, 127 families were divided into twelve types and seven variants at family-level, 369 genera were divided into fourteen types and twelve variants at genus-level.Tropical elements take obvious advantages, part of subtropical elements, nevertheless there lack the relic plants.Thirdly, we conduct that part of native plants of Pingtan Island and continential plants were different.A number of plants were native strand plants, which showed typical coastal features.Lastly, the relationship between the flora of exotic plants and native plants had a very significant correlation.At the meantime, exotic plants had a great influence on Pingtan Island flora and distribution types.关键词
