| 摘要: |
| 运用桑沟湾多元养殖生态模型，模拟得到了桑沟湾浮游植物和无机氮营养盐的年变化规律、水平分布的季节变化。结果表明,浮游植物生物量和无机氮营养盐浓度存在明显的季节变化，养殖活动的季节性增大了二者的季节变化幅度；桑沟湾浮游植物和无机氮营养盐的分布受大面积海带和贝类养殖的影响；外海营养盐补充是桑沟湾内无机氮营养盐的主要来源。 |

| Study on ecosystem model of multi species culture in Sanggou Bay:Ⅱ Simulation of ecosystem and the circulation of nutrients |
|
|
| Abstract: |
| Based on the multi species culture ecosystem model in Sanggou Bay, the annual variation cycles and seasonal distributions of phytoplankton biomass and dissolved inorganic nitrogen (DIN) concentration were simulated. Model results indicated that the seasonal aquaculture activities made seasonal variations of DIN concentration and biomass of phytoplankton more prominent. The distributions of DIN and phytoplankton biomass were mainly influenced by the aquaculture scenarios. During the period of kelp culture, DIN from the open sea is an important source of nutrient supporting the growth of kelp, due to the exchange of water. |
