浙北安吉龙王山维管植物区系分析

浙江北部安吉龙王山共有维管植物１３０８种、６亚种、８１变种。区系成分以温带属为主，占６０３０％；种在国内以长江以南的分布类型为主，占５２２３％。从区系成分、优势科属、生活型等方面看，龙王山维管植物区系与天目山、黄山有密切联系。首次记录了睫毛蕨科（Ｐｌｅｕｒｏｓｏｒｉｏｐｓｉｄａｃｅａｅ）在浙江分布。文中还就华中植物区系通过大别山向华东迁移以及区系研究中若干问题进行了讨论。

Analysis of vascular plant flora at Longwangshan, Anji, northern Zhejiang Province

1 308 species, 6 subspecies and 81 varieties of vascular plants were investigated at Longwangshan, Anji, Zhejiang Province. The flora was dominated by the temperate distribution types (60.30%), based on genus census; it was characterized by the southern Yangtze distribution type (52.23%), based on species census. In consideration of distribution types, dominant groups and life form, the flora at Longwangshan was thought to be closely related to those for Tianmu Mountain and Yellow Mountain. Pleurosoriopsidaceae was newly recorded in Zhejiang. Several problems with flora analysis were discussed. The authors suggested that the Central Chinese Flora might migrate to East China via Dabie Mountain.
