摘　　要：于2013年5月和11月在厦门近岸海域设置67个站位进行大型底栖动物定量调查,运用Brey(1990)经验公式对该海域的次级生产力进行估算。结果表明:该海域大型底栖动物年均总次级生产力P和P/B值分别为4.6±10.1 g AFDW·m-2·a-1和1.0±0.4a-1,软体动物和多毛类为该海域P值的主要贡献类群,秋季的P值略高于春季,同安湾的P值明显高于大嶝海域、九龙江口、厦门外海域和围头湾。相关性分析显示,该海域次级生产力与沉积物有机质含量以及水体底温呈显著相关,底质类型以及采砂、航道清淤、环境污染等人类活动干扰也是影响次级生产力分布的主要因素。We investigated the macrozoobenthos at 67 stations in Xiamen coastal waters in May and November 2013, and calculated the secondary productivity （P） of the macrozoobenthos using Brey＇ s empirical formula （1990）. The results showed that the mean secondary productivity and the P/B ratio were 4.6±10.1 g AFDW ·m^-2·a^-1 and 1.0±0.4 a^-1 respectively. Molluscs and annelids contributed to the vast majority of the P value. The P value was slightly higher in autumn than in spring, and it was significantly higher in Tongan Bay than in Dadeng area, Jiulong River estuary, the outer sea of Xiamen and Weitou Bay. Correlation analysis indicated that the P value was significantly affected by the organic matter content of sediment and the temperature of bottom water. The nature of the bottom sediment and human activities such as sand excavation, waterway dredging, and environmental pollution also influenced the distribution of P.
