一个描述在二维空间中单一种植或混合种植的植物群体内病害时、空流行动态的计算机随机模拟模型构建完成。模型由寄主、病原2个组分和病斑产孢、孢子传播、孢子着落、孢子侵染、病斑潜育、寄主生长、病害控制等一系列代表病害流行生物学过程的子模型构成。模型采用了面向对象的 A computer-generated stochastic simulation model for the dynamics of empty flight was constructed to describe the in vivo disease of a single plant or mixed plantation in two-dimensional space. The model consisted of a series of sub-models representing the epidemiological processes of disease, including host and pathogens, sporulation of spores, spore spread, spore population, spore infection, lesion spotting, host growth and disease control. The model uses object-oriented
