摘要： Disclosed is a nonlinear optimization method for parameters of ocean ecological dynamics model, comprising the following steps: acquiring a state variable set and a parameter set to be optimized; building an ocean ecological dynamics model; acquiring a final cost function equation group; solving the ocean ecological dynamics model to obtain numerical solutions of each state variable; acquiring a Hamilton function of the cost function equation group under a constraint condition, and acquiring an adjoint equation based on the Hamilton function; adjusting the parameter set to be optimized based on the adjoint equation to obtain an optimal parameter set.
