摘要
基于随机扰动的影响,建立一个具有年龄结构的线性随机种群模型.根据实际测量值,利用统计学方法给出相应的观测方程,对具有观测方程的种群模型设计卡尔曼滤波器来滤出种群生长中的不良扰动,维持了种群生态系统的平衡.
Based on random disturbation, a stochastic model of population with age- structure is proposed; Based on real data, the corresponding measure equation is given, a Calman filter is designed to reduce tile harmful disturbation on population growth, which maintain the balance of ecological system.
