中文摘要:
      基于国外大型底栖动物次级生产力的评估方法,结合国内研究现状,选取了3种Brey模型对胶州湾大型底栖动物的次级生产力进行估算,通过2015-2017年连续3个季度对胶州湾海域大型底栖动物的调查,最终结果表明:胶州湾大型底栖动物的次级生产力与其他海域相比具备较高的水平,次级生产力的季节性变化明显,其中夏季为最高;湾内高值区位于湾顶中部红岛以南到向西偏移至大沽河口和红石崖附近。分析发现历年来大型底栖动物群落的物种组成基本保持稳定,菲律宾蛤仔(Ruditapes philippinarum)资源的变化是造成次级生产力变化的最主要因素。研究推荐使用Brey (2012)模型来估算胶州湾大型底栖动物次级生产力,春、夏、秋季的估算结果分别为880.17、1 537.64、458.33 kJ/(m2·a)。
英文摘要:
      Based on the methods to evaluate the secondary production of macrozoobenthos abroad, as well as the domestic related research status, three different Brey's empirical models were selected to calculate the secondary production of macrozoobenthos in Jiaozhou Bay. The secondary production of local macrozoobenthos was investigated in every spring, summer and autumn of 2015-2017. The results showed that:The secondary production of macrozoobenthos in Jiaozhou Bay was higher than other areas. It had obvious seasonal variation, with the highest value in summer. The high value area was in central northern part of the bay near Hongdao, and in the west part of the bay near Dagu River estuary and Hongshiya. Compared with the historical data, which indicated that the taxa composition of macrozoobenthos in Jiaozhou Bay was very stable within the latest 30 years, while the aquaculture of Ruditapes philippinarum may contribute mostly to the changes of spatio-temporal patterns of the macrozoobenthic secondary production in the study area. The Brey (2012) model was recommended to use to estimate the secondary production and the results in spring, summer and autumn were 880.17, 1537.64 and 458.33 kJ/(m2·a), respectively.
