| Abstract: | This paper studies the qualitative property of the third kind functional reaction model of prey species with the rates of constant invsest in nondense restrict prey-predatory system. It is proved that the limit cycles of this system, under a certain condition, possesses enistence, nonexistence and aniqueness. |
