Abstract：After open-pit mining of limestone,the resulting exposed slopes and soil depletion exhibit characteristics of desertification,posing key challenges in mine ecological restoration.To optimize ecological restoration technologies for limestone open-pit mines and enhance restoration efficacy,57 typical limestone open-pit mines already treated in Xuzhou are assessed.Using the TOPSIS method,six indicators across three categories—soil quality,vegetation quality,and geo-morphic reconstruction—were evaluated.The findings show that spray seeding greening technology yields the best restor-ation results,followed by slope greening and platform greening.Other methods like retaining soil cofferdams and vegeta-tion holes demonstrate relatively lower effectiveness.Based on these results,parameter optimization for existing restora-tion techniques and design specifications are proposed,providing a practical reference for ecological restoration of similar limestone open-pit mines.
