鱼类种群动态模型的滤波分析

Filtering Analysis of Fish Population with Dynamics Model

在确定性具年龄结构的Ｌｅｓｌｉｅ矩阵模型基础上，考虑具有随机性的非线性补充，使得模型能反映随机因素。利用扩展的Ｋａｌｍａｎ滤波方法，实现量测更新、动态预报，并通过仿真例子进行比较分析。

Based upon Leslie matrix model with a definite age structure, the consideration of the non-linear complement at random enables the model to reflect some of the random factors. Applying Kalman filtering method extended, a renewed measurement and a dynamic forecast are achieved. And also, both the comparision and the analysis are proceeded through simulated examples.
