中文摘要：

建立了一个与考虑养殖阻力的水动力模型耦合的、以浮游植物生物量、无机氮浓度、悬浮有机颗粒物浓度、海带生物量为变量的桑沟湾三维多元养殖生态模型。模型考虑了养殖生物海带对海水流动的阻碍作用随其生长的动态变化,以及养殖生物和浮游植物之间对无机氮营养盐的竞争。最后,分别以浮游植物生物量和海带产量为目标变量,对参数的敏感性进行了分析。

英文摘要：

A multi-species culture ecosystem model coupled with a dynamic model that takes the culture drag into consideration was established.This three-dimensional model involved four variables： phytoplankton biomass,dissolved inorganic nitrogen （DIN）,particulate organic matter （POM） and kelp biomass.The model focused on the variation of the drag caused by kelp growth,and the competition of nutrients between kelp and phytoplankton.Finally,sensitivity of the parameters were analyzed.
