Abstract: During coal mining activities, the integrity and function of terrestrial ecosystems are facing serious threats, and the ecological restoration of collapsed areas is related to the sustainable manifestation of the ecological value of coal mining areas. The article is based on a multi-objective optimization model of ecosystem value, and designs various ecological restoration strategies for water resource management, land use, and biodiversity protection to develop comprehensive ecological restoration plans for coal mining subsidence areas, including efficient utilization of water resources, restoration of vegetation cover, promotion of species reproduction, and restoration of ecological functions, The research results have important theoretical and practical significance for the ecological restoration of coal mining subsidence areas.
