Abstract: Based on ivestigation and statical analyses,the flora of seed plants of Fengyangshan Nature Reserve(Mt. Fengyangshan) in Zhejiang Province is studied in the present paper.There are 1448 species and varieties,659 genera and 164 families of seed plants in the nature reserve. The areal types of families,genera and species are analyzed respectively. The pantropic type of families reaches 40.9%,cosmopolitan type 20.7%,and north temperate one 19.5% according to the statisics of plant families,which indicates that temperate elements are less than tropic ones(47:81). The pantropic type is 20.5%,the north temperate type is 18.0% and the East Asia one 17.1% at generic level,and the temperate elements are slightly more than tropical one(308:277).

摘要： 在野外调查和分类处理的基础上，报道了浙江凤阳山种子植物区系的统计分析结果。现知凤阳山有种子植物164科、659属、1488种(含种下分类群)。科、属、种的分布区类型分析表明：科的分布区类型以泛热带分布最多(40.9%)，其次是世界分布(20.7%)和北温带分布(19.5%)，温带分布少于热带分布(47:81)；属的分布区类型以泛热带分布最多(20.5%)，其次是北温带分布(18.0%)和东亚分布(17.1%),温带分布略多于热带分布(308:277)；种的分布区类型以中国特有分布最多(46.9%)，其次是东亚分布(26.0%)和热带亚洲分布(13.7%)，温带分布远多于热带分布(501:264)，显示出明显的亚热带山地植物区系的性质。以区系分区区划作为分析地理分布特征的单位，将凤阳山的中国特有分布型划分为9个亚型，以华东－华中－华南分布亚型占有最大的比例,反映上述区系的密切联系。
