Evolutionary Game Analysis for Grassland Degradation Management, Considering the Livelihood Differentiation of Herders

Grassland degradation has become one of the most important ecological and environmental problems in world, affecting balance grassland welfare residents. To reveal impact mechanism herders’ livelihood constraints on degradation, to explore comprehensive management methods ensure livelihoods restoration, this paper constructed an evolutionary game model considering local governments herders. It is found that ideal stable equilibrium can be achieved when certain conditions are met, is, actively regulate herders moderate grazing, caused by overgrazing reduced. The differentiation significantly affects state game. government’s regulation key promoting grazing effect incentive measures limited, while punishment restrict excessive behavior Policy support for household effectively motivate achieve their survival development needs a greater extent through non-grazing livelihood. research results help decision-makers formulate policies combat promote improvement lives.
