基于中日合作长江口海域生态围隔的试验数据，建立了长江口海域六分量赤潮生态动力学模型，并用海上实测数据进行了检验，进而详细讨论了营养盐及光照强度对赤潮形成的影响。结果表明，此次海洋生态围隔试验加入营养盐无机磷所达到的浓度对于诱发该赤潮过程是适宜的。随着初始Ｎ浓度的降低，Ｐ增加到一定程度便不再影响叶绿素浓度分布。当光照为原光照强度的 ５０％时，叶绿素浓度最高可达３５μｇ／ Ｌ。长江口海域发生赤潮无机氮和无机磷营养盐浓度阈值分别为 ４．５μｍｏｌ／ Ｌ和 １．０μｍｏｌ／ Ｌ。该模型结合水动力学模型不仅可以对海洋赤潮现象进行预测及海洋水质环境的总量控制，也可直接应用于海水养殖，对施肥及养殖容量提供理论指导。
Based on the experimental data of Sino-Japanese cooperation in the ecological estuary of the Yangtze Estuary, a six-component eco-dynamic model of the red tide in the Yangtze Estuary was established and tested with the sea-based measured data. The effects of nutrients and light intensity on the formation of red tides were discussed in detail. The results showed that the concentration of inorganic phosphorus in nutrient marine enclosures tested in this study was suitable for inducing the red tide. As the initial N concentration decreased, P increased to a certain extent will no longer affect the chlorophyll concentration distribution. When the light is 50% of the original light intensity, chlorophyll concentration up to 35μg / L. The threshold values for the concentrations of inorganic nitrogen and inorganic phosphorus in the Yangtze River estuary were 4.5μmol / L and 1.0μmol / L, respectively. The model combined with hydrodynamic model not only can predict the phenomenon of marine red tide and control the total amount of marine water environment, but also can be directly applied to mariculture and provide theoretical guidance for fertilization and culture capacity.
