Characteristics of main plant communities on uninhabited islands in Bohai Sea,China
Nine uninhabited islands with different sizes,laying on the coast of Bohai Sea,were selected as research objects for a further understanding and study of the characteristics of plant communities.By using the method of sample plot survey,we investigated a total of 66 sample plots,covering the study of species composition,and the number of individuals,height and diameter at breast height(DBH)of woody plants,etc.140 species of vascular plants belonging to 38 families and 98 genera were investigated through sampling plot method.The results showed that Asteraceae,Poaceae,Fabaceae were the most abundant families in the communities.Moreover,the native forest vegetation has been replaced by secondary ones dominated by Robinia pseudoacacia,Pinus thunbergii,Ailanthus altissima,and Ulmus macrocarpa,respectively.Meanwhile,temperate deciduous shrubland became zonal vegetation type in this area,and the representative communities are dominated by Ziziphus jujuba var.spinosa,Periploca sepium,Flueggea suffruticosa,Celastrus orbiculatus,respectively.And representative herbaceous alliances are dominated by Artemisia argyi,Suaeda salsa,A.capillaris,and Themeda triandra,respectively.In general,the species diversity of island plant communities is relatively low,belonging to vulnerable vegetation.
