摘要
为研究不同植被恢复年限对复垦土壤生物肥力的影响和作用,通过野外调查及采样分析,对安太堡露天煤矿复垦区不同恢复年限下土壤的理化性质、土壤酶活性、土壤微生物数量和多样性进行了研究。结果表明,不同复垦年限的土壤酶活性不同,复垦20 a的土壤酶活性优于复垦15,10 a和对照;不同复垦年限对土壤微生物数量和多样性的影响作用不同,复垦20 a的土壤微生物数量和多样性高于复垦15,10 a和对照。植被恢复可以促进土壤生态肥力提高,改善土壤质量。
To research the effects of different reclamation years on reclaimed soil biological fertility quality, the soil physicochemical properties, soil enzymatic activity and soil microbe were studied in reclaimed soil with different reclamation years in Antaibao large opencast coal mine. The results showed that the soil enzyme activities were different in different reclamation years. The soil enzyme activity of 20 years was better than that of 15, 10 years and CK. The effects of different reclamation years on soil microbial quantity and diversity were different. The amounts of soil microbe and diversity of microbial biomass reclaimed 20 years were higher than that of 15, 10 years and CK. Vegetation restoration could promote soil ecological fertility and improve soil quality.
