害虫-天敌系统生物和农药控制的系统动力学仿真

System Dynamics simulation models for biological and pesticide control in the pest natural enemy system

运用系统动力学原理与方法，建立了害虫－天敌系统的生物或农药控制的仿真模拟模型，对若干控制策略进行了情景模拟，得到一些有益的结果．说明了系统动力学方法是开展田间害虫优化控制决策研究的有效的实用工具．

The principles and methods of System Dynamics were used to establish the simulation models for biological or pesticide control in pest natural enemy system. Favourable results were obtained by simulation of several control strategies, which indicated that the methods of System Dynamics were feasible means of research on the strategies to optimize the field pest control.
