摘要
本文建立由鼠类和天敌二要素构成的捕食—食饵模型,推导出自然生态条件下鼠类数量与天敌数量的平衡关系式,并据此说明了天敌对鼠的数值反应和功能反应的作用是使系统趋于平衡.
: A dynmic model consisting of the rodent and preda-tor is proposed. The quantity equilibrium formula between rodent and predator is deduced in natural ecology. And the formula can be used to formulate that the function of numerical responses and func-tional responses is to maintain system' s equilibrium.
