Abstract:Objective To assess the soil properties remediation effectivenessacross diferent reclamation directions, informoptimal strategy selection.MethodsFocusing oncoal mining reclamation areas,a multi-level evaluation model wasdeveloped. Using field sampling laboratory testing,soil characteristics at varying depths were analyzed,with remediation efectivenessevaluatedvia the entropy-weighted TOPSIS method.Results Significant differenceswere observed inmost indicatorsexcept pH,total nitrogen,total phosphorus bacterial abundance.Fly ash -remediatedcropl showedsuperiorrestorationcompared to vegetable fields orchards.Reclaimed areasperformed lower thanundisturbed l butexceeded unreclaimed sitesdemonstrating mining'simpactsreclamation'sbenefits.A significant linear relationship between wheat biomass remediation scoresconfirmedtheTOPSIS model's reliability.Conclusion These findings provide theoretical support for soil quality improvement strategies.

Key words : reclamation area;entropy-weighted TOPSIS method;soil quality;remediation efectiveness
