摘要

Watershed ecological compensation is a key factor for safeguarding the environment and ecology of water. Scientific compensation standards are pivotal for establishing an effective mechanism. While existing studies on such standards have been focused mainly on water quality and quantity, ecological compensation dynamics remain underexplored. In this study, a calculation paradigm for watershed ecological dynamic compensation standard intervals is constructed by coupling evolutionary game theory and bargaining game theory (two game models) and by leveraging their dynamic analysis capabilities, incorporating ecosystem dynamics and upstream‒downstream stakeholder interest demands. The main findings include the following: (1) the coupled game-based calculation paradigm captures the complexity and uncertainty of multiple influencing factors in watershed ecological compensation and (2) when applied to the Xiangjiang River Basin (XRB), the calculated compensation interval is [2.37-16.818] billion USD, which reflects the socioeconomic dynamics and the fairness-efficiency balance between upstream and downstream regions, making it reasonable and effective. This study provides theoretical and practical guidance for formulating ecological compensation standards, ecosystem restoration, and mechanism establishment in the XRB and similar watersheds.
