Effects of different reclaimed measures on soil carbon mineralization and enzyme actives in mining areas

Ecological degradation in the mining areas are greatly aggravated in recent decades. Ecological restoration has become the primary measure for the sustainable development, especially in Shanxi Province where mine industry has been one of the pillar industries. In this paper, we tested the effects of different regeneration scenarios and fertilizer treatments on soil organic carbon mineralization and enzyme actives in reclaimed opencast mining areas. We analyzed the effects of regeneration scenarios and fertilizer treatments on oil organic carbon dynamics and enzyme actives, and the relationships between soil enzyme actives and different active carbon through quantitative ecology method. Soil carbon-cumulative mineralization and enzyme activities were more sensitive to fertilizer treatments and regeneration-fertilizer interaction than soil pH, bulk density, organic carbon and nitrogen. Therefore, the sensitive diversity indices of soil carbon-cumulative mineralization and enzyme activities could be as good indictors to assess the effects of mining reclamation measures.
