摘　　要：病虫害是制约农业生产的重要因素,每年因病虫害造成的损失巨大,如何对病虫害进行有效的控制是亟待解决的问题。有效掌握病虫害的发生规律,可对病虫害的发生发展进行预测,为实际生产提供帮助。目前已有的关于害虫时空动态模拟的方法主要有数学模型方法、GIS技术和复杂系统建模方法,存在的主要问题是如何兼顾表达害虫动态变化的时间特征和空间特征,以及在模拟过程中对害虫动态变化与相关因素关系的真实反映。Diseases and insect pests are important factors that restrict the agricultural production.The lost caused by it is so huge every year. How to control the diseases and insect pests effectively is the problem to be solved urgently. It is helpful to grasp the occurrence nile of diseases and insect pests for predicting the occumence and development of diseases and insect pests and helping the practical production.There are mathematical model, GIS technology and complex system modeling method to make the temporal and spatial dynamic stimulation. The main existing problems included that how to express both the time characteristics and spatial characteristics of the insect pests dynamic changes and the real reflection of the relationship between the insect pests dynamic change and related factors.
