The impact of environment on individuals is particularly critical. In evolutionary games, adopting the strategy neighbor who performs better nontrivial for survival and maintenance cooperation, in that such an action may help agents to obtain higher benefit more obvious advantages. Inspired by this idea, we investigate effect environment-based preference selection evolution cooperation spatial prisoner's dilemma. A simple rule, incorporating individual via adjustable parameter α explore how potential sources influences behavior traits, considered. Because social interaction not be only way generating payoffs, assume individual's income also affected environment. Besides, taking into account differences, introduce heterogeneity Through numerous computing simulations, find selection, which accelerates microscopic organization cooperator clusters resist aggression defectors, can truly promote within a large range parameters. Our study indicates combination key sustainability structured populations.
