根据中日合作海洋生态围隔试验观测资料，对乔方利等１９９８年提出的赤潮过程生态模型（乔方利等，２０００）进行参数优化研究，得到赤潮过程营养盐半饱和常数：硅藻，ＫＮ＝１．４μｍｏｌ／Ｌ、ＫＰ＝０．１２９μｍｏｌ／Ｌ、ＫＳｉ＝１．１６μｍｏｌ／Ｌ；鞭毛藻，ＫＮ＝０．３４５μｍｏｌ／Ｌ、ＫＰ＝０．１１３μｍｏｌ／Ｌ以及其它等共１８个参数的最优取值，并详细讨论了目标泛函的构造和多目标函数参数优化的方法。 According to the observational data of China-Japan cooperative marine enclosures, the optimization of the parameters of the red tide ecological model (Qiao et al., 2000) proposed by Qiao et al. In 1998 was conducted to obtain the half-saturation constants of nutrients in the red tide: KN = 1.4μmol / L, KP = 0.129μmol / L, KSi = 1.16μmol / L, dinoflagellate KN = 0.345μmol / L, KP = 0.113μmol / The best value, and discussed in detail the construction of the target functional and multi-objective function parameter optimization method.
