浙江省湿地维管束植物区系研究

摘要

The second surveying on wetland plant resources in Zhejiang demonstrated that there are 1403 species of vascular plants which belongs to 604 genera and 157 families. Geographical distribution of families could be divided into 9 types, dominated by pantropic family, accounting for 57.6% of the total one. Geographical distribution of genera could be divided into14 types, accounting for more than 90% of national types. Among 14 types, pantropic and north temperate types accounted for 27.6% and 21.4%. The result showed that flora of wetland plants in Zhejiang province has the feature of subtropics, transferring from subtropics to north temperate.%浙江省第二次湿地资源调查结果显示，浙江省共有湿地维管束植物1403种（含种下等级及栽培种，下同），隶属于157科，604属，种类十分丰富且重点保护物种较多。浙江省湿地维管束植物区系起源古老，地理成分复杂。其科的地理分布可划分为9个类型，以泛热带分布成分最多，含49科，占总科数的57.6%（不含世界分布，下同）；属的地理分布类型共计14种，占全国属的地理分布类型的90%强，其中泛热带分布成分和北温带分布成分较多，各占27.6%和21.4%。数据表明本区系的亚热带性质，以及亚热带到北温带过渡的区系特征，同时也反映出本区系湿地植物与世界各地区植物有着广泛的不同程度的联系。
