[0002] As the global demand for renewable energy increases, the construction of wind power projects has expanded rapidly. However, while wind power projects bring clean energy, they also have certain negative impacts on the ecosystems in which they are located, including land occupation, habitat destruction, and reduction of ecological service functions. At present, the ecological impact assessment of wind power projects is mostly focused on environmental quality assessment, lacking a comprehensive quantitative analysis of the value of ecosystem service functions, which makes it difficult to effectively balance the relationship between ecological protection and energy development during the planning and construction of wind power projects.
