摘要
生物灾变中害虫预测是智能农业中害虫管理专家系统的重要组成部分,也是有效防止和控制害虫发生与发展的依据。介绍了现有生物灾变中害虫预测基本原理和方法,通过对稻纵卷叶螟的种群动态、发育、产卵量建模,求解引发害虫灾变的触发点和临界值,实现稻纵卷叶螟的灾变预测,以便在灾变发生前采取相应措施,化解大发生种群的形成。
The pest catastrophe prediction in ecology catastrophe is one of important part in expert system of intelligence agriculture and also the guarantee for preventing and controlling the pest catastrophe occurrence efficiently. The paper introduced the basic principles and methods of current catastrophe prediction in ecology catastrophe. According to modeling for the dynamic process of population, up-grown and amount of spawn, the paper found out the trigger point and critical value inducing the pest catastrophe and implemented the catastrophe prediction of cnaphalocrocis medinalis guenee, which took measures before catastrophe to prevent big population coming into being.
