摘要
本文将幼年害虫种群数量作为害虫控制的指标,建立了具有阈值策略的非光滑Filippov系统的害虫增长模型,将害虫数量控制在合理密度范围内,系统地分析了滑线系统、等倾线以及平衡点的存在性问题.
In this paper, we take the number of juvenile pests density as a control indicator of pest number, then, the pest growth model of non-smooth Filippov system with economic threshold strategy is established. We control the number of pests within a reasonable range of density, and the existence of sliding line system, null-isoclines and equilibria axe systematically analyzed.
