2012年对围海造地后的福宁湾特殊生境海区开展春季、夏季两季的生态调查,研究底栖生物群落生态现状。两航次调查共鉴定底栖动物57种,其中软体动物24种,多毛类19种,甲壳动物9种等。总栖息密度407.5个/m2,其中软体动物占有65.6％的明显优势；总生物量为338.44g/m2,其中软体动物占有98%的绝对优势。种类数、生物密度和生物量三项指标,均为春季显著高于夏季,堤内高于堤外；聚类分析表明,季节是影响群落时空变化的主要因子；堤内外群落的差异主要与沉积物类型密切相关。

Six stations were established to investigate the benthos in funing bay Land reclamation in spring and summer of 2012. 57 species of benthos are indentifided in the two cruises, among which there were 24 species of Mollusca, 19 species of Polychaeta, 9 species of Crustacea. The total benthis density is 407.5 ind/m2 and most of them are the Mollusca (65.6%). The total benthis biomass is 338.44 g/m2 and most of them are the Mollusca (98%). Species number, biomass and density in spring were significantly higher than in summer, and increased from the open sea to inside estuary. Results of Cluster indicate that seasonal succession answer for tht fluctuation in the communities of benthos, while the types of sediment answer for the differences between the the open sea and inside estuary.
