In order to realize the community characteristic of Cerasus subhirtella var.ascendens better,the study was conducted in Fujian Wuyi Mountain and Jiangsu Baohua Mountain based on the field investigation.The results show that the floristic composition has significant difference in different areas,which indicates the community of Wuyi Mountain(Ⅰ) is the most complicated and Baohua Mountain(Ⅲ) is the simplest among them,including 261 species, 144 genera,and 64 families of spermatophyte plants;the similarity of floristic composition among the communities is low,and the proportions of constant families,genera and species are 52.94%,27.97% and 10.48% in turn;according to the Raunkiaer frequency law of ABC=DE to analyse,the species frequency is ABCDE,which illustrates the species are uneven distribution in the communities and the vegetation has the tendency of differentiation and evolutionary.
