To reasonably determine the design parameters for ecological restoration of mine quarry slope,based on the concept of multi-objective decision-making,this paper proposes a set of technical schemes for optimizing the design parameters of ecological restoration of high and steep rock slopes in mine quarries for the first time.Taking the ecological restoration and treatment engineering design of high steep rock slope in an abandoned limestone quarry in Guangxi as an example,this study carried out a case study and propo-ses a multi-objective decision-making model with geological safety,ecological restoration benefit,and pro-ject cost with slope,slope height,and slope platform width as parameters.The gray relational analysis eval-uation model was used to assess and optimize the proposed schemes,leading to the identification of the opti-mal design parameter combination of the slope ecological restoration and treatment project.The results in-dicate that the optimal combination of slope cutting design parameters is a 75° slope,6 m slope height,and 3.5 m platform width.The multi-objective decision-making scheme and model suggested in this paper can provide essential references for the ecological restoration design optimization of similar projects and have a good practical application value.
