浙江丽水国家重点保护野生植物区系研究

调查统计表明,丽水共有国家重点保护野生植物28种,隶属14科23属,裸子植物9种,被子植物19种,其中国家1级保护植物4种,Ⅱ级保护植物24种。丽水国家重点保护野生植物区系具有种类丰富、过渡性强、成分特有及起源古老等特征,从种的地理分布和属的分布区类型的分析可以看出,该区系与华南、华东联系密切;属的分布区类型以中国特有分布最多(21.74%),其次分别是东亚与北美间断分布(17.38%)、东亚分布(13.04%)和北温带分布(13.04%),温带分布略多于热带分布(11∶7)。

Floristic Analysis of the National Key Protected Wild Plants in Lishui

According to the investigation and statistics,there were 28 species,belonged to 14 families and 23 genera in Lishui,of which 9 species of gymnosperm,and 19 species of angiosperm,of which 4 species belonged to the first grade of protected plants and 24 species belonged to the second grade of protected plants.The characteristics of flora of the national key protected wild plants were analyzed and discussed as follows: the national key protected wild plants were rich in species;there were many ancient relice lements;the floristic interims were obvious;the endemic to china flora were outstanding.The distribution types of the genera of national key protected wild plants and geographic distribution of the species in Wenzhou are analyzed.The result showed that the flora has more association with the South China and East China.The endemic type of China wa 21.74%,the east Asia & north disjuncted America distribution type was 17.38% and the East Asia one 13.04%,North temperate one 13.04% at generic level,and the temperate elements are slightly more than the tropical ones(11∶7).
