Based on the survey of macro-algae in the intertidal zone of Island Dongji Zhejiang province from August 2010 to May 2011, the algal species composition and distribution are presented. The algal similarity in the sampled areas is preliminarily analyzed using Similarity indices （Sc）. A total of 107 species sampled in sublittoral area are identified, among which, 17 species of 7 genera belong to Chlorophyta, 73 species of 40 genera belong to Rhodophyta, and 17 species of 12 genera are categorized into Rhodophyta. Rhodophyta are the dominant species, with the occurring frequency being up to 68.2%. In addition, 80.4% of sampled species are collected from low-tide zone, and some are gathered from the extended area, that is, from mid-tide zone to low-tide zone. The composition comparability between mid-tide and low-tide species is found to be 0.54, and the convergence effect in mid-tide and low-tide zone is higher than that in high-tide and mid-tide zone. The sublittoral area of Dongji shows obvious vertical zoning character. The dominant species in spring season are listed in this paper in detail. Based on the experiment carried out in this work, the Biomass ofSargassum horneri is noted as high as 22.97kg·m^-2, the Biomass of Sargassum.thunbergii is 15.11kg·m^-2, the Biomass of Scytosiphon lomentarius is 8.41kg·m^-2, and the Biomass of Corallina officinalis reads 1.76-2.80kg·m^-2.
