摘　　要：We studied the effect of population density in a spatial public goods game.We found that the effect on the evolution of cooperation is very complex when the strategy learning and mobility of players in a long range are considered in a two-dimensional lattice.As the learning range is larger than the mobility range,the system is driven to enter into a cooperation state for a low population density,because a small local group is beneficial to sustain a high level of cooperation.As population density increases to a moderate range,the mobility of players from a domain invaded by defectors supports the evolution stability of cooperation.When the mobility range is larger than the learning range,a formation of compact domains of cooperators promotes cooperation as the population density becomes high.
