摘　　要：浙江大罗山有种子植物740种,隶属于413属128科,其中裸子植物5科11属12种,被子植物123科402属728种。通过区系成分分析及其与周邻植物区系聚类比较,结果表明大罗山种子植物区系成分复杂多样,科属组成以寡、单种类型为主;区系地理成分以泛热带、北温带、东亚、旧世界热带、热带亚洲和东亚北美成分为主,具有明显的热带、亚热带向温带过渡的性质;本区与纬度接近的浙江北仑山、白云山、北山区系关系最为密切,但热带成分所占比例却显著高于这三个地区。There are 740 species of spermatophyte,subordinate to 413 genera, 128 families,including gymnosperm with 6 families, 16 genera, 31 species and angiosperm with 133 families, 513 genera, 976 species in Daluo Mountain,Zhejiang Province. This paper analyzed the floral composition of Daluo Mountain and it＇s compared with its neighboring flora. It was concluded that the floral composition of Daluo Mountain was complex and multiplex,and the composition of family and genus mainly consisted of few or single species; The floral geographic elements mainly consisted of Pantropic, North Temperate, East Asia, Old World Tropics, Tropical Asia and East Asia ＆ North America, and obviously had the characteristics of transition from Tropics,Semi tropics to Temperate;Daluo Mountain had the closest floral relationship with Beilun, Baiyun and Bei Mountain, but its percentage of tropical elements was remarkably higher than these three mountains.
