摘　　要：采用FVCOM模型生成三维物理场,基于个体模型参数化黄海日本鲐早期生活史过程,通过拉格朗日质点追踪的方法将模拟生成的4—8月物理场与生物模型耦合,构建基于个体的黄海日本鲐的早期输运动力学模型。模拟结果表明:所构建模型可以较准确地模拟出青岛石岛外海(青外)产卵场黄海日本鲐鱼卵和仔鱼的输运路径、密度分布及在黄海海域的滞留情况。研究发现,在平均气候条件下,青外产卵场的日本鲐在产卵之后总体向山东半岛南部输运,日本鲐鱼卵和仔鱼最终分布于32°N~37°N和121°E~124°E海域内,并在中韩渔业协定暂定措施水域(以下简称协定水域)有大量分布。从4月产卵开始,西部产卵场内部分日本鲐鱼卵和仔鱼就开始陆续进入协定水域中,并在7—8月间已有50%的超级个体进入协定水域中的40~80 m等深线内并被滞留超过300 h,说明该产卵场对协定水域的日本鲐资源补充贡献较大。日本鲐鱼卵和仔鱼的生物斑块密度和滞留区主要集中在34.5°N~37°N和121.3°E~124.3°E海域内,并确定该海域为黄海日本鲐仔鱼的主要育肥场,该育肥场有3/5的范围属于协定水域,说明协定水域的物理环境对青外产卵场的日本鲐资源补充量影响很大。不同年份间日本鲐鱼卵和仔鱼的输运分布具有明显差异,造成黄海日本鲐的输运分布产生年际差异的主要动力学原因是黄海冷水团的冷中心位置。By adopting FVCOM-simulated 3-D physical field and based on the biological processes of chub mackerel(Scomber japonicus)in its early life history from the individual-based biological model,the individual-based ecological model for chub mackerel at its early transport dynamics in the Yellow Sea was constructed through coupling the physical field from April to August with the biological model by the method of Lagrange particle tracking.The results showed that the model can accurately simulate the transport path、density and retention distribution of eggs and larvae of chub mackerel in the spawning ground in Qingdao Shidao offshore in the Yellow Sea.The study found that under average climate conditions,chub mackerelin the spawning ground in Qingdao Shidao offshore was overall transported to the southern part of Shandong Peninsula after spawning,eggs and larvae of chub mackerel were finally distributed in the range of 32°N-37°N and 121°E-124°E,and had a large distribution in the waters of the provisional measures of the China-Korea Fisheries Agreement(hereinafter referred to as the waters of the Agreement).Since spawning in April,some eggs and larvae of chub mackerel have begun to enter the waters of the Agreement,and from July to August,50% of the super-individuals have entered the 40-80 m isobath in the waters of the Agreement and have been stranded for more than 300 hours,illustrating the spawning ground in Qingdao Shidao offshore contributes significantly to the replenishment of chub mackerel resources in the waters of the Agreement.The biopatch density and retention area of eggs and larvae of chub mackerel were mainly concentrated in the sea area of 33.5°N-37.5°N and 121°E-124.5°E,and this sea area was determined to be the main fattening ground for larvae of chub mackerel in the Yellow Sea,and 3/5 of the fattening ground was in the waters of the Agreement,indicating that the physical environment of the waters of the Agreement had a great impact on the replenishment of chub mackerel resources in the spaw
