植物虫害防治已不只是农林生产中的常规问题,它早已演变成为生态环境与食品安全中的重大应用问题.然而,人类对该问题的认知远远不足以为现实应用提出令人满意的有效指导.这其中也是由于植物昆虫种群可以纳入“多生命体-环境”为对象的复杂系统研究范畴.面对这样极具挑战性的科学问题,本文主要从计算机建模的研究路径对模拟植物昆虫种群动态的数学建模方法进行回顾,从模型构造方法和模型所考察研究对象的种类两方面对植物昆虫种群模型进行了分类;将目前的植物昆虫种群动态模型用通用数学表达式表达,并针对各类型的植物昆虫种群动态模型对数学表达式进行特殊说明,进一步强调了模型间的差异;介绍了目前比较成熟的几个模拟昆虫种群动态发展的软件;总结了基于植物昆虫种群动态模型研究种群动态行为、害虫防治技术所采用的数学分析和优化控制方法.文章最后探讨了目前植物昆虫种群动态模型的研究现状和发展趋势,以及在建模时所应考虑的问题,并对进一步完善模型方法及技术应用进行了展望.
Plant pest control has not only become a common problem in agriculture and forestry production, but it has evolved into a major application problem in ecological environment and food safety, however, human’s knowledge of the problem is far from enough to provide satisfactory and effective guidance for practical applications This is also due to the fact that plant insect populations can be involved in the study of complex systems for “multi-living organisms-environment.” Facing such a challenging scientific problem, this paper focuses on computer modeling from the research path of simulated plant Insect population dynamics are reviewed. The model of plant insect population is classified from two aspects: the model construction method and the type of the object investigated by the model. The current plant insect population dynamics model is expressed by common mathematical expressions The dynamic model of plant insect species is used to explain the mathematical expressions and further emphasize the differences among the models. Some mature softwares to simulate the dynamic development of insect populations are introduced. The dynamic models based on plant insect populations are summarized Mathematical Analysis of Population Dynamic Behavior and Pest Control Techniques Optimal control method. Finally, discusses the current research status and development trend of dynamic models of plant insect population, as well as issues that should be considered when modeling, and to further improve the model approach and technology were discussed.
