摘要
根据厦门地区(厦门岛、鼓浪屿、大嶝岛)1990年2月至1992年1月调查软相潮间带所获资料,研究了该区多毛类的种类组成、数量与分布。结果表明,该区多毛类种类丰富,共鉴定出118种(含未定种),隶属于37科83属。其中,高潮区40种,中湖区90种,低潮区83种。多毛类平均栖息密度87个/m2,平均生物量3.339/m2。数量有明显的季节变化。密度为春>夏>秋>冬,生物量则夏>春>秋>冬。其种类多样姓(H’)平均3.90,均匀度(J)平均0.70。多毛类的分布受沉积类型和潮汐的影响显著。
The ecology of soft intertidal polychaetes is studied based on the data obtained from the seasonal surveys of three islands in Xiamen area from February, 1990 to January, 1992.Identified are 118 species belonging to 83 genera, 37 families, among which 40 species occurred in high tide zone, 90 in middle tide zone and 83 in low tide zone. The mean density and biomass of polychaetes were 87 ind. /m2 and 3. 33g/m2, respectively. There were obviously seasonal variation of polychaete quantity. The mean density was the highest in spring,the second in summer, the third in autumn and the lowest in winter. The mean biomass was in the order of summer, spring, autumn and winter. The species diversity (H') and evenness (J) for polychaetes were 3. 90 amnd 0.70 in average, respectively. The distribution of soft intertidal polychaetes is influenced by environmental factors such as sediment type and tides.
