The ecology of benthos in Fujian mangrove swamps
福建红树林区底栖生物生态研究

The paper describes the community structure,the characters of fauna and the relationship between the distribution and inhabiting environments of the benthic fauna in the mangrove regions along the coast of Fujian during October,1984 and May,1985.Among the total 278 species,we found algae with 11 species,Polychaeta with 47 species,Mollusca 72 species,Crustacea 88 species,Echinodermata 11 species,fishes 27 species,and other animal groups 22 species.The dominant and common species are mainly the eurythermic and eurytopic species and also the subtropical warmwater species.Brachyura crabs and Mollusca are major animal groups.The averages of the biomass and the densities of the benthic fauna in all 8 sections are 33.74g/m 2 and 136ind/m 2 respectively.the species abundance and polymorphism in the community are positively corelated to the mean salinity of the sea water,but are negatively interretated to the development of mangrove.The density of the benthic animals are positively corelated to the development of the mangrove.
