Abstract: In this paper, the two-species prey-predator Lotka-Volterra model with the Holling’s type Ⅲ is discussed. By the method of coupled upper and lower solutions and its associated monotone iterations, the existence of solutions for a strongly coupled elliptic system with homogeneous of Dirchlet boundary conditions is derived. These results show that this model admits at least one coexistence state if across-diffusions are weak.

Key words: reaction diffusion system, strongly coupled, coexistence
