| 摘 要： | <正>根据林木生长的随机性和动态性,用CAR模型自动辩识机辩知林木生长“多对多”动态系统的阶、参数。然后把得到的差分方程组变换成状态矩阵方程,在此基础上对林木生长动态进行Kalman滤波和实时预报,并给出了预报精度。

| Abstract: | In this paper, an automatic CAR model identifier is proposed to show the parameter and order of dynamic forest-tree growth sysfem and then the difference equation group obtained will be transformed into a state matrix equation, on this basis, the Kalman filtering and forecasting are carried out for the forest-tree growth. The precision of forecasting is also discussed. |
