退耕还林背景下流域横向生态补偿博弈分析OA

The implementation of basin ecological compensation holds significant importance for enhancing water resource utilization efficiency and promoting ecological conservation and high-quality development.However,the rationality of compensation standards has remained a persistent challenge in compensation practices.Building upon the context of China's Grain for Green Project(a large-scale afforestation/grassland restoration initiative),this study innovatively explores a framework for calculating basin ecological compensation standards from a generalized water resource perspective.The proposed methodology integrates three core components:① a water footprint-based compensation model to quantify ecological service value flows and determine compensation direction,② a total cost revision model for accounting ecological protection expenditures,and ③ a water resource valuation method to establish market-oriented pricing mechanisms.By coupling these models with game theory simulations of inter-basin negotiation processes,the research examines compensation rationality through a case study of the Yanhe River Basin.The findings demonstrate that the water footprint model effectively identifies ecological service supply-demand relationships,calculating the minimum compensation the downstream parties are willing to accept from the upstream at 43 million yuan.The total cost revision model reveals significant disparities between the downstream payment willingness(upper limit of 331 million yuan)and the upstream cost recovery thresholds(minimum of 192 million yuan).Cooperative game modeling yields Nash equilibrium solutions:when the downstream pays 199 million yuan of ecological compensation to the upstream,and the upstream provides 63 million yuan of ecological compensation to the downstream as ecological compensation,the overall benefits of the basin can be maximized.The study validates that coupling multiple calculation methods to assess compensation willingness,combined with game-theoretic analysis of cooperative equilibria,provides a robust reference framework for implementing horizontal ecological compensation mechanisms.This approach offers viable solutions for balancing ecological protection and regional development in water resource governance.
