Abstract :
Based on spatial prisoner´s dilemma theory proposed by Nowak, a model is built to character the evolution of cooperation in heterogeneous population, dismissing the assumption that all agents in population are homogeneous. The influence of the population diversity and spatial structure is studied. The revealing simulation results shows that the cooperation degree in heterogeneous population is much higher than that in homogeneous population, the conclusion is that the will to get heterogeneous resource is an important reason to cause the cooperation. Another result different from past researches is that the randomization degree of the spatial structure has no obvious effects on the time from initial state to quasi-stable state
