为了了解福建省湄洲湾潮间带底栖生物的物种多样性、数量时空分布及群落结构现状, 2005年11月和2006年4月在湄洲湾潮间带选择了灵川(Mch1)、苏厝(Mch2)、郭厝(Mch3)、东吴(Mch4)和东桥(Mch5)5条断面进行了调查。共鉴定潮间带底栖生物225种, 其中多毛类、软体动物和甲壳动物占总种数的88.00%, 三者构成潮间带底栖生物的主要类群。断面间比较, 东桥断面种数较多, 苏厝断面较少。季节比较, 春季各断面种类较秋季多。平均生物量22.91 g/m2, 以软体动物居第一位, 甲壳动物居第二位; 平均栖息密度为388个/m2, 以多毛类居第一位, 软体动物居第二位。生物量以中潮区>低潮区>高潮区; 栖息密度以低潮区>中潮区>高潮区。调查结果显示湄洲湾潮间带底栖生物物种多样性较高, 群落结构相对稳定。

In order to understand the biological diversity and the stability of intertidal communities in Meizhou Bay, and to conduct assessement on the environmental quality, we investigated the benthic diversity in Meizhou Bay, Fujian Province in November 2005 and April 2006. A total of 225 species of intertidal benthos from shore wetlands in Meizhou Bay was reported. Polychaetes, Molluscs and Crustaceans accounted for 88% of all species. The number of benthic species differed between transects and was greater in spring than autumn. Average biomass and density were 22.91 g/m2 and 388 inds./m2, respectively. In terms of biomass, Molluscs exhibited the highest and Crustaceans the second, and in terms of density Polychaetes showed highest, followed by Molluscs. Biomass of middle tidal zones was higher than that of high or low tidal zones. Density of benthic invertebrates among tidal zones, ranked from highest to lowest, was as follows: low tidal zone, middle tidal zone, and high tidal zone. Both biomass and density were lowest in the high tidal zone. Both biomass and density were higher in spring than in autumn. Using the ABC (abundance biomass comparison) curve to analyze the structure of the intertidal community in Meizhou Bay, it was found that the overall disturbance is not apparent. The results suggest that this area retains some of its environmental carrying capacity.
