中文摘要：

2003年9月—2004年9月隔月在胶州湾西部的5个站位进行了7个航次的大型底栖动物调查取样．利用Brey经验公式对大型底栖动物的丰度、生物量、次级生产力和P／B值进行研究．结果表明，该海域大型底栖生物年次级生产力平均值为47．34g·m^-2·a^-1．平均P／B值为0．58．相关分析表明，叶绿素a是影响次级生产力的重要因子，与南黄海缇鱼产卵场、渤海及国外相关海域的结果进行比较表明，在局域尺度上叶绿素a是最重要的影响因子，但在区域尺度上次级生产力随水深增加而降低．分析对次级生产力影响最大的菲律宾蛤仔种群的年龄组成发现，该种群主要是由不足1龄、1龄和2龄个体组成．

英文摘要：

From September 2003 to September 2004, seven cruises bimonthly survey was conducted on the macrobenthos at five research stations in the Jiaozhou Bay, and the abundance, biomass, secondary productivity, and P/B value of the macrobenthos were studied by using Brey＇ s empirical formula. The results showed that the secondary productivity of the macrobenthos was averagely 47.34 g·m^-2·a^-1, and the mean P/B value was 0. 58. Correlation analysis indicated that Chl-a was the important environmental factor affecting the secondary productivity. A comparative study on the southern Yellow Sea, Bohai Bay .and other areas also proved that on local scale, Chl-a was the important factor affecting the secondary productivity of the benthic community, but on regional scale, water depth was more determinative, i. e. , this productivity was decreased with increasing water depth. The greatest contributor to the secondary productivity of macrobenthos in studied areas was Ruditapes philippinarum, the most important economic bivalve in the Jiaozhou Bay, and its pop ulation was dominated by the individuals with the ages of less than one year, one year, and two years.
