Firstly , the identification of the double medium system is considered , the existence , the uniqueness and the boundness of the solution of the system of the partial differential equations are proved by using the monotone method , the mathematical model of the parameter identification problem is established , and under some mild assumptions , the optimality system about the identification is derived , thus the suitable gradient methods can be employed to solving the identification problem . secondly , the theories of optimal control of distributed parameter system are introduced to investigate the parameters identification problem involving the three - dimensional population system
利用单调方法证明了正问题解的存在惟一性和有界性，建立了相应参数识别问题的数学模型，并给出了求解这类识别问题的最优化系，从而可利用适当的梯度法，实现对系统参数的识别；把分布参数系统最优控制理论引入到具有多个识别参数的三维种群生态系统的参数识别问题之中，给出了参数识别问题最优解的存在性结论，证明了状态方程的解对识别参数的连续依赖性和g (
