Abstract: An ordinary differential equation system model is established to study the effects of intra-specific high-order interaction,inter-specific high-order interaction and density-mediated effect,as well as the integration of the three on population density.MATLAB numerical simulation shows that intra-specific high-order interaction and inter-specific high-order interaction can promote the coexistence between prey and predator,and the influence intensity and density-mediated effect are similar,but the action mechanism is different.

Key words: intra-guild predation system, high-order interaction, density-mediated, population density, coexistence
