摘  要：
采用查阅资料和专题调查以及标本鉴定相结合的研究方法,对南岳衡山种子植物区系组成、代表类群及其相关性进行分析。结果表明:该区有野生种子植物164科692属1 572种,占中国中亚热带常绿阔叶林植物属、种的94.15%和57.41%。南岳衡山种子植物区系有优势科(属)22科(66属);种子植物表征科(属)38科(75属),植被(群落)优势科(属)25科(49属)。种子植物含10种以上且超过平均VFEC的科(属)的分布类型与该区科(属)的实际分布类型最为相似;植物区系优势科(属)、表征科(属)和植被(群落)优势科(属)两两对应的相似系数为1.56%～47.06%(0.80%～30.36%);南岳衡山种子植物区系表征科、属宜在含10种以上且超过平均VFIC的科(属)中确定。植物区系优势科(属)、表征科(属)和植被(群落)优势科(属)是3个生态学意义不同的、各自独立的植物区系中的属性指标。

摘  要：
The floristic composition,typical groups and their correlations analysis of seed plant in Nanyue,Hengshan Mountain were studied with the method of combination of data access and thematic surveys and specimen identification.The results were showed: There are 1 572 species to belong to 692 genera to belong to 164 families on the wild seed plant occupying 94.15% of genera and 57.41% of species of middle subtropical ever-green wild-leaved forest of China.There are 66 dominant genera,22 dominant families,75 character genera,38 character families in the seed plant floristic and 49 dominant genera and 25 dominant families in the vegetation.The distribution type of seed plant floristic with a VFEC higher than average value and more than 10 species in it was similar to the actual distribution type of it.4.The correspond similarity coefficient of dominant,characteristic family and dominant family of the vegetation held 1.56%~47.06% and that of dominant,characteristic genera and dominant genera of the vegetation held 0.80%~30.36%.The characteristic genera and family should be defined in the genera or family with more than ten species and a VFIC higher than mean.The dominant family(genera),the characteristic family(genera)and the dominant family(genera)of vegetation were three independent ecological index of floristic.
