摘    要:
对具有常数投放率和非线性功能反应的一类食饵-捕食者两种群模型t=xg(x)-yφ(x)+h,y=y(-d+eφ(x)),在相对增长率为g(x)=a—bx^a,捕食率为φ(x)=ex^a时进行了研究.讨论了该系统平衡点的稳定性态、解的有界性及其极限环的存在情况.

关 键 词:食饵-捕食系统  平衡点  有界性  极限环

Abstract:
A class of two species predator-prey model with functional response and constant stocking rate x =xg(x) -yφ(x) +h,y=y(-d-eφ(x)), , when relative increasing rate is g ( x ) = a - bx^a and prey rate φ (x) =ex^a is studied. The stability of equilibrium, boundedness of solutions and existence of limit cycle are discussed.
Keywords:predator-prey system  equilibrium  boundedness  global stability
