Abstract: Based on the analysis of the existing problems in reclaiming abandoned mining land and their negative effect on the ecological environment,and in view of the limited factors to reclaim abandoned mining land,this paper puts forward the suggestions of using sewage sludge as an alternative in mining land reclamation.Application of sewage sludge in reclamation has beneficial effects, such as increasing organic matter content, preventing soil erosion,recovering vegetation,and promoting microbial population and its activities Unfavorable factors including heavy metal and organic pollutant for applications of sewage sludge and their countermeasures are also discussed.

Key words: typical steppe, degradation, soil physicochemical properties, soil microorganism, soil enzyme activity.
