| Abstract: | The community composition, distribution, seasonal variation and biomass of benthic algae in the harbour region of Qinhuangdao during the period from April to October of 1983 are studied. The results of the investigation are as follows. 1. 85 species of benthic algae were collected. They are indentified as: 18 Chlorophyta, 19 Phaeophyta, 47 Rhodophyta and 1 Xanthophyta, 32 species belonging to 23 genera are reported for the first time in this area. 2. The communities of different stations are different. The community composition of algae were dominated by Ulva pertusa, Enteromorpha intestinalis and Urospora pincilliformis in Xinmei Matou, by Corallina officinalis, Symphyocladia lotiuscula, U. pertusa and Codium fragile in Dengta and by U. Pertusa, C. fragile, Scytosiphon lomentarius and Grateloupia finicina in Jinshsanzui. 3. The biomass and seasonal variation in each sea area are different. The biomass in Jinshanzui was the highest, where the highest was in April. The second high was in Xinmei Matou, where the highest was in August. The lowest was found in Dengta, where the highest was in August. |
