Abstract: During the development of coastal zone and neighbor islands in Shanghai, biotic and abiotic environmental factors are playing important roles. Among them, the age and the height of the islands, soil type, nutrient, salinity and pH of soil influence the formation, colonization and succession of the plant communities. On the basis of field work for several years, applying 2-D ordering of Canonical Correspondence Analysis(CCA) of ecological multivariate analysis, the diversities of plant communities and species of coastal zone and neighbor islands in Shanghai were analyzed. Meanwhile, the situation of plant community succession and the environmental factor of all kinds of habitats were analyzed. All of these investigation results will give basic information for the research on coastal zone and neighbor islands as well as the whole ecological system in Shanghai.
