一种嵌入模糊集的天敌治虫的生态方程

An Ecosystem Equaton Inlaid With Fuzzy Sets of Elimination of Insect Pest by Natural Enemy

根据天敌昆虫赤眼蜂与农业害虫如螟虫等之间生存竞争的特点,构造出一个生态方程。又根据赤眼蜂产卵活动与螟虫孵化的主要影响因素的温度的最适的数值域,拟定了一个模糊集合,用以确定生态方程中的参数。对生态方程的稳定性分析和数值模似,得出一些有意义的结果。

Based on the characteristics of the sturggle for existence between trichogramma and moth's Larva, We establish an ecosystem equation. Then,based on the optimum values of air temperature and humidity,which affect the trichogramma oviposition,we draw up a fuzzy set,and use it to decide Parameters of ecosystem equation. We make stability analysis of the ecosystem equation,and simulation test on computer, Finally, we achieve some significant results.
