一类稀疏效应下具Ⅱ类功能反应生态系统的定性分析

QUALITATIVE ANALYSIS OF A Ⅱ TYPE FUNCTIONAL REACTION ECOLOGICAL SYSTEMS UNDER SPARSE EFFECT

本文对一类食饵种群在稀疏效应下具有HollingⅡ类功能性反应和常数存放率的食饵──捕食者系统进行定性分析，研究了系统平衡点的性态及全局稳定性，证明了系统极限环的存在唯一性，并解释了生态意义．

In this paper,the authors consider the Ⅱ type functional reaction system under sparse effect.We proved the existence,uniqueness of limit cycles and the global stability of non-trivial equilibrium points of system,and explained the ecological meaning.
