The relationships between the predator and prey s population number were studied with Meta Analysis Method.
应用 Ｍｅｔａ 分析方法，探讨捕食者与被捕食者种群数量的关系。
This paper builds an ecosystem model, in which corresponding attributive definitions are given to the predator (wolf) and the prey (sheep), and the grass is defined as recyclable resource.
建立了一个基于网格由狼羊草组成的生态系统模型,模型中对捕食者(狼)及被捕食者(羊)给予了相应的属性定义,把草界定为可再生资源,通过引入“超结构”的规则,解决了采用Monte Carlo方法模拟时网格状态不能同步更新的问题。
Study on Mathematical Model of a Class of Predator Communituy and Prey Community;
本文通过对一个微分方程组的奇点分析，轨线分布情况及全局稳定性的讨论（文中对捕食者种群的吸收率K（x）用三段函数来表示），得出结论：无论两个种群的原始数量如何，随时间的推移，总要稳定在正平衡点（1／2，3r／8）上，从而揭示了错综复杂的生物圈内，捕食者种群与被捕食者种群间的捕食关系。
