摘要
为了解野生藤本植物区系的特点,采用野外调查与资料查阅相结合的方法,对公园内的藤本植物进行调查和区系分析。结果表明:白云山地区野生藤本植物有32科77属183种(含种下分类群)。分别占白云山野生种子植物的21.77%、13.23%、15.63%。属水平上,本区以单种属和寡种属为主,分布类型以泛热带占优势(28.60%),其次是东亚分布(14.29%),热带亚洲分布也占据了一定的比例(11.70%);种水平上,种的分布类型以中国特有种为最多(59%),其次是东亚分布(16.40%)、热带亚洲分布(15.30%),其余类型为零星分布。按照区系分区标准,将中国特有种分为7个亚型,其中以华东-华中-华南分布最多(57种)。可见,白云山地区藤本植物种类丰富,地理成分复杂多样,拥有较多的特有植物。可以为本市的绿化提供材料。
In order to explore the characteristics of wild vine plants florae in the forest park of Baiyun Mountain in Zhejiang Province, according to the field investigation and the document collection, the floristic characteristics of the wild vine plants were analyzed. The result showed that：there were 183 species in 77 genera of 32 families of wild vine plants found in this area. Accounting for 15.63% in species, 13.23 % in genera and 21.77% in families of the seed plants from Baiyun Mountain. At genus level,71 genera, which in- clude only 1 species or 2 - 5 species. The pantropic was main type which occupies 28.60%, much bigger than the East Asia type （ 14. 29% ）, and the Tropic Asia type （ 11.70% ）. At species level, the Endemic to China type was most （59%）, followed by the East Asia type（ 16.40% ） and the Tropic Asia type（ 15.30% ） ,other types just had small proportion. Based on the subarea of China,the endemic species to China can be divided into 7 subtypes, the subtype of East China-Central China-South China had much more spe- cies than others, reaches 57. The vine in Baiyun mountain was very rich, the ingredient of flore was multiplex, it had many endemic. It also can provide materials for City Landscaping.
