Study on the Ecological Compensation Mechanism of Bosten Lake Basin in Xinjiang Based on Evolutionary Game
The basin ecological compensation can effectively solve the externality issues generated in the process of resources development and utilization,and it is of great significance in promoting the coordinated development of economy-society-ecology in the basin.Based on the evolutionary game theory,this paper analyzed the tripartite dynamic evolution scenarios of the higher government and the upper and lower lo-cal governments.Taking the Bosten Lake basin in Xinjiang as the research object,it set up a basin ecological compensation mechanism.The results indicate that only when the fines imposed by the higher government on the defaulting party are higher than the ecological protection costs and compensation fees in the upstream and downstream of the basin,the upstream and downstream can reach a stable equilibrium state of"protection"and"compensation"strategies.Based on the evolution results,the ecological compensation and ecological protection cost of Bosten Lake are 2.64×107 and 2.20×107 Yuan/year.Adopting the"compensation method for key pollution factors exceeding the standard"to determine penalty standards.The penalty standards based on exceeding the standard for CODMn,NH3-N and TP pollutants are 1 312.51,9 181.56 and 13 115.08 Yuan/t respectively.
