油松毛虫种群动态的ARMA(p,q)模型

ARMA (p, g) Model for the Population Dynamics of Chinese Pine Caterpillar

应用随机过程理论建立了油松毛虫上树后至化蛹阶段的ARMA(p,q)模型,并对该阶段的种群动态进行了模拟,其模拟值与实测值十分接近。

Using the stochastic process theory, an ARMA (p,q) model of the larvae of the Chinese pine caterpillar was established for the up-tree to pupation stages. In addition, the population dynamics of the stage were simulated and the simulated value corresponded significantly to data.
