| 摘 要： | 本文运用简单的概率思考,对两种天敌与一种害虫的捕食行为或拟寄生行为给出互不相容的,相容的,及相互独立的统计描述。对近年来由Hassell、May、Beddington等人为了提供生物防治的理论依据,所提出的天敌与害虫相互作用数学模型中作用率(捕食率,拟寄生率)给以确切的概率涵义。并对两种天敌与一种害虫的不同形式的相互作用,提出5个数学模型,其中有的是改进前人的模型,有的是田间生态系统中常见的,而尚未有人提出过的。文中还分别就随机寻找和非随机寻找两种情况下,将模型参数的变动影响及种群动态的趋势进行了数值模拟。

| Abstract: | In the present paper, by simple probability consideration, the incompatible, compatible, and independent features of predation or parasitoid behaviours between two natural enemy populations are distinctly considered.The precise probability implications are given for the predation or parasitoid rate in several mathematical models recently developed by Hassell, May and Beddington. And, mathematical models of nearly realistic interactions between two natural enemies (P,Q) and one pest (N) are presented as in t... |
