| 摘 要： | 根据2004年在厦门海域22个取样站获得的4个季度的大型底栖动物调查数据以及历史资料,发现软体动物双壳纲的光滑河蓝蛤(Potamocorbula laevis)是厦门海域大型底栖动物群落的局部、季节性优势种;环节动物多毛纲的昆士兰稚齿虫(Prionospio queenslandica)是局部优势、周年常见种。春季和夏季,光滑河蓝蛤在鼓浪屿附近海域的密度分别为1098.8个/m2和1720.0个/m2,夏季,在曾厝安附近海域的密度为3773.3个/m2,均占所在海域大型底栖动物密度的50%以上,而冬季和秋季,很少采集到光滑河蓝蛤。夏季和秋季,昆士兰稚齿虫在鼓浪屿附近海域的密度分别为871.3个/m2和232.5个/m2;从季度平均值看,昆士兰稚齿虫密度和生物量夏季最高,秋季次之,春季第三,冬季最低;昆士兰稚齿虫的优势度没有光滑河蓝蛤高,但在整个厦门海域均有一定的密度和生物量。本研究分析了光滑河蓝蛤、昆士兰稚齿虫数量与有机质、硫化物含量、水动力等环境因子之间的关系。

| Abstract: | According to macrofaunal data got seasonally at 22 sampling stations in Xiamen Harbor in 2004 and history data,we found that Potamocorbula laevis (Bivalvia: Corbulidae) becomes a new local and seasonal dominant species,and Prionospio queenslandica (Polychaeta: Spionidae) becomes a new local dominant species and yearly common species. The density of Potamocorbula laevis was 1 098.8 ind./m2 and 1 720.0 ind./m2 in the sea water around Gulang Island in spring and summer respectively,and was 3 773.3 ind./m2 in the sea water near Zengcuo-an in summer. All the densities above exceed 50% of macrofaunal density. Potamocorbula laevis was few in winter and autumn. The densities of Prionospio queenslandica were 871.3 ind./m2 and 232.5 ind./m2 in the sea water around Gulang Island in summer and autumn respectively. The density of Prionospio queenslandica was the highest in summer,the second in autumn,the third in spring and the lowest in winter. The density of Prionospio queenslandica was not so higher than that of Potamocorbula laevis,but Prionospio queenslandic distributed in whole Xiamen sea water and in all seasons. In this paper,the relationships between the quantities of two species and contents of organic matter,sulfide,and hydrodynamic were analyzed. |
