摘要
本文对一类食饵种群带有常数存放率,捕食种群具有厌食行为的生态系统进行了定性分析。较详尽地研究了系统可行平衡点的分布及性态,得到了极限环的存在与不存在的条件,并解释其生态学含义。
Anoraxia predator-prey system under constant stocking rate of prey is x=x〔(a-ax)-αy/(1+ωx+βx^2)〕+G y=y〔-c+kαx/(1+ωx+βx^2)〕 discussed in this paper. It mainly studied the local behaviour and global behaviour of feasible equilibrium points. The conditions of the existence and unexistence of limit are obtained. The corresponding ecological meanings are interpreted.
