2009年10月对大亚湾海域的小型底栖动物丰度和生物量进行了研究。结果表明, 小型底栖动物的平均丰度为(593±265)ind·(10cm)))2, 呈湾内向湾外递增趋势; 平均生物量和生产量分别为(568.39±294.49)μg·(10cm))2 (干重)和(5115.53±2811.14)μg·(10cm))2 (干重)。在分选的17个主要类群中, 海洋线虫在丰度上占绝对优势达92.24%, 其次是多毛类和桡足类, 分别为2.05%和1.98%。在生物量上, 海洋线虫(38.47%)和多毛类(29.97%)为绝对优势类群, 其次是寡毛类(13.82%)和介形类(9.15%)。在垂直分布上, 占总量约53.02%的小型底栖动物和51.44%的海洋线虫分布于0—2cm表层。统计分析表明, 本海域的小型底栖动物生物量与含水率、中值粒径和黏土+粉砂含量呈显著负相关(P<0.05), 多毛类的生物量与小型底栖动物表现的显著相关性相同, 桡足类的生物量与中值粒径值呈显著负相关(P<0.05), 与沉积物的黏土+粉砂含量呈极显著负相关(P<0.01), 而线虫生物量与环境因子无显著相关关系。由海洋线虫与桡足类的数量比(用N/C表示)与本海域环境状况的分析表明, 该数值可以在一定尺度上为海洋环境检测提供参考。

The abundance and biomass of meiofauna in Daya Bay was investigated for the first time based on samplings obtained from 9 stations in October 2009. The average abundance of total meiofauna amounted to (593±265)ind·(10cm))2, which showed the tendency of increase from littoral sea to open sea. The average biomass and production reached (568.39±294.49) and (5115.53±2811.14)μg·(10cm))2(dwt), respectively. Among the 17 main meiofaunal groups sorted, free-living Nematoda dominated 92.24%, followed by Polychaeta (2.05%) and Copepoda (1.98%). In terms of biomass, Nematoda and Polychaeta represented absolute predominance and accounted for 38.47% and 29.97%, respectively, followed by Oligochaeta (13.82%) and Ostracoda (9.15%). In vertical distribution of the average abundance in the top 0?10cm sediments, 53.02% of the total meiofauna and 51.44% of the nematodes occurred in the top 0?2 cm depth. Statistical analyses showed that the abundance of meiofauna and Polychaeta was negatively correlated to the weight percentage and sediment particle size, and copepods were negatively correlated to sediment particle size only. This study suggests that the abundance ratios of nematodes to copepods (N/C) might be a useful indicator for indicating marine environmental pollution to a large extent.
