摘要： This paper discusses a model of two coeffected species with diffusion system,where the birth functions have the characteristic index decline, and then the eircumstance factors a: which are connected with natural resources, and the birth parameters βi which could be controlled are introduced.By means of the upper-lowersolutions,the existence,uniqueness and the local stability of equilibrium solution of the moel are discussed.It’s discovered that the birth parameters βi determine the developing tendency when other parameters are comparatively stable.
