［Objective］ To address the difficulties in quantifying the ecological losses caused by mining activities and the ecological benefits resulting from ecological restoration in mining areas， a scientific and credible assessment system for the ecosystem value of mining areas were constructed， in order to provide scientific references for enhancing the ecological value and ecological environment restoration and management in these areas. ［Methods］ To address the insufficient sensitivity of existing assessment methods for ecological service value to mining disturbances and ecological restoration effects， this study proposed an assessment system for the ecosystem value of mining areas based on the logical framework of ‘conceptual framework-indicator selection-system construction-application evaluation and verification’， focusing on four core functional values： ‘material production， energy flow， material cycling， and information transmission’. The assessment system was applied and validated at Buliangou mining area， Inner Mongolia. ［Results］ ① Among the four major functions of the mining area ecosystem， the energy flow function， driven by mining activities， contributed significantly to ecosystem value， reaching 688.317 9 million yuan/km² in 2022. ② The material cycling function， which included water conservation， windbreak， and sand fixation， was more significantly affected by compound disturbances， while the material production and information transmission functions were less affected. ③ Since the implementation of concentrated ecological restoration in 2019， the functional value of the mining area’s ecosystem had shown a positive improvement， with the ecological value in restored areas increasing by an average of 9.80×10⁴ yuan/km². The ecological value loss caused by mining disturbances exhibited a fluctuating decline. ④ The values of the four ecological functions demonstrated an overall “U-shaped” trend in response to variations in mining intensity. ［Conclusion］ The energy flow function significantly affects the total ecosystem value， while the material cycling function is a key influencing factor of the spatial heterogeneity of the ecosystem value in the mining area. The Buliangou mining area still requires enhanced ecological restoration to improve its ecosystem value.
