摘　　要：为了解辽东湾海域底栖动物次级生产力水平和时空分布特点,根据2007年的4月和10月辽东湾海域大型底栖动物调查数据,运用Brey经验公式计算大型底栖动物次级生产力和P/B值,并结合海洋生物指数方法对辽东湾海域进行生境适宜性评价。分析结果表明,该海域大型底栖动物年平均次级生产力为5.59g/(m^2·年),年平均P/B值为3.16,辽东湾大型底栖动物次级生产力空间分布呈现出自沿岸向中部递增的趋势,P/B值空间分布与底栖动物次级生产力相反,呈现出自沿岸向中部递减的趋势,群落组成中以个体小、生活史短、代谢快的底栖动物为主。The secondary productivity and P/B value of macrozoobenthos were estimated by Brey empirical formula and the suitability of habitat was evaluated by AMBI method based on the survey data of macrob- enthos in Liaodong Bay in April and October of 2007, in order to get the secondary productivity level and the characteristics of spatial and temporal distribution of zoobenthos in Liaodong Bay. The results showed that the annual average secondary productivity of the macrozoobenthos was 5.59 g/（me ~ a）, and the an- nual average P/B value was 3. 16. The spatial distribution of secondary productivity of macrozoobenthos showed a trend of increasing from the coast to the middle part, but the spatial distribution of P/B value was opposite from the zoobenthos secondary productivity, presenting the trend of decreasing from the coast to the middle part. The community composition was mainly of zoobenthos with small individuals, short life history and fast metabolism.
