| 摘 要： | 以我国近海典型海带养殖区桑沟湾为例,建立了"浮游植物-海带-浮游动物-营养盐-有机碎屑"生态动力学模型,较好地模拟了不同养殖密度下浮游生态系统结构的变化,通过灵敏度分析,研究状态变量对模型初值和参数变化的响应,提出了参数优化的思路. |
| 关 键 词： | 海洋生态动力学模型 灵敏度分析 海水养殖 参数优化 |

| Abstract: | Sanggou bay which is very typical in kelp mariculture in China was selected as studied site,a ecosystem dynamics model comprised by phytoplankton（P）,kelp（K）,zooplankton（Z）,nutrient（DIN and DIP） and detritus（D） has been set up.The change of pelagic ecosystem structure under different mariculture densities of kelp was simulated.The responses of state variables to initial values and parameters of model have been studied through sensitivity analysis.Finally,an idea about optimization of parameter of ecosystem dynamics model was suggested. |
| Keywords: | marine ecosystem dynamics model sensitivity analysis mariculture optimization of parameter |
