摘　　要：应用Mironenko建立的反射函数理论,研究了一个生态模型.给出其反射函数的第一分量为x1时所满足的条件,以及此时其第二分量具有的具体形式.当该系统为周期系统时,讨论其周期解的性态.Based on the reflecting function theory developed by Mironenko,the necessary and sufficient conditions of an ecological model have been studied when its first component is x1,and the form of its second component has been gotten.When this system is periodic,the condition for the existence of the periodic solutions has been established.

关 键 词：微分系统 反射函数 周期解
