Hydropower,as a clean and renewable energy source,plays a crucial role in achieving carbon neutrality goals.Howev-er,balancing the economic benefits of hydropower development with its environmental impacts necessitates a thorough exploration of ecological compensation mechanisms.We took the Maerdang Hydropower Station in the upper Yellow River as the case,ana-lyzed its ecosystem service values in 2015 and 2021 by using the ecological value equivalent method.Then we predicted its eco-system service values after water impoundment in 2025,in combination with the prediction of the land use change by remote sens-ing data.Then we put forward a reasonable ecological compensation reference scheme.The results indicate that from 2015 to post-reservoir filling,ecosystem service values such as hydrological regulation and water resource provision have increased signifi-cantly due to the conversion of grassland,forestland,and cropland to water bodies.However,other services like climate regulation,soil conservation,and biodiversity have shown slight declines.Overall,ecosystem service value exhibits a moderate upward trend.Specifically,the ecological compensation amount for 2021 was RMB 11.291 billion,with an anticipated increase to RMB 11.367 billion post-reservoir filling,with the Maqin County area prioritized for compensation.Given uncertainties related to climate change and other factors,this study emphasizes the importance of interdisciplinary approaches and long-term monitoring,and it provides an initial exploration of applying ecological compensation mechanisms across the entire lifecycle of hydropower projects.
