摘　　要：本文根据我所1980年8月至1981年10月厦门港湾海洋环境综合调查,选取其季度月(11,2,5,8月)资料,研究该港湾蟹类的种类组成、数量分布与季节变化。Based on the quantitative and qualitative data obtained from 54 dredger stations and 13 trawler stations in three investigated areas in Xiamen Harbor from August, 1980 to August, 1981 ,this paper reports the ecological features of species composition,density and biomass distribution of crabs in four seasons. The results indicate abundant number of crabs in the Harbor. All together 58 species of crabs have been identified,most of them being tropical and subtropical warm species. 35 of the species arc dis tributed widely in the Indo-West-Pacific tropical area and 39 species also presented in Japanese coastal waters. The annual average values of the density and biomass of carbs in the three areas were 10 ind./m^2 and 1.60g/m^2 respectively. In the West Harbour of Xiamen area had the highest density and the Xunjiang of Xiamen area the lowest. Biomass was the highest in the Xunjiang of Xiamen area and the smallest in the Jiulong River estuary and the Outer Xiamen Harbour. As for the seasonal variation the higher density of areas occurred in spring and summer and the lower in autumn and winter. The higher biomass was generally in spring and summer(except for thd Jiulong River estuary and Outer Xiamen Harbour where the biomass in spring was lower than in winter )and the lowest in autumn. The species composition , seasonal variation difference of the habitat density and biomass of crab in the areas in relation with the hydrologic factors and the grain size of the sediments are also discussed in this paper.
