摘  要：
基于吴征镒等的种子植物科、属分布区类型系统和聚类分析方法,对分布于江西省的三清山、井冈山、军锋山、官山及邻近的浙江省开化县莲花山等6个长柄双花木所在群落植物区系多样性进行了研究。结果表明:对所有群落物种的初步鉴定统计得出50科170属283种,区系组成复杂。从科、属、种分布类型分析可知,地理成分多样。各长柄双花木群落植物区系的热带性分布类型和温带性分布类型比例相当,具有热带区系和温带区系交汇过渡的特征。区系成分聚类分析表明,各地长柄双花木群落具有较高的相似性,它们在地理亲缘关系上存在着密切的联系。

摘  要：
Based on the analysis of the cluster and areal types of family and genera of seed plants by Wu Zheng- yi,the floristic diversity of 6 communities with Disanthus cercidifolius var. longipes in different areas(Sanqing Mountain,Jinggangshan Mountain,Junfeng Moutain and Guanshan Mountain in Jiangxi Province;Lianhuashan Mountain in Kaihua County,Zhejiang Province) were studied. The results showed that the floristic composition of the communities is complex,there are 283 species belonging to 170 genera and 50 families based on preliminary identification and statistics of all the communities. The distribution type analysis of families,genera and species indicated that the geographical elements are diverse. There are similarities and differences in the floristic characteristics of the 6 communities,there is extensive relationship among the florae. According to the floristic elements of families and genera,the tropical distribution is of the same ratio as the temperate one,indicating the transitional floristic characteristics from the tropic zone to the temperate zone. The floristic element clustering analysis showed that the florae of the 6 communities are closely related.
