摘　　要：[目的]为金属尾矿的植物修复提供依据。[方法]通过高羊茅盆栽试验对不同处理铜尾矿基质的基本理化性质、土壤酶活性进行了研究。[结果]相对于空白组,种植高羊茅能改善土壤理化性质,增加土壤肥力,提高土壤酶活性。[结论]脲酶活性对环境改变最为敏感,可以作为植物对铜尾矿污染土壤修复效果评价的一个优先选用指标。[Objective] The aim was to provide the basis for phytoremediation in heavy mental tailings.[Method] Pot experiments with F.arundinacea were conducted in different treatments of the copper tailings.Soil physical and chemical properties,soil enzymatic activities in F.arundinacea were studied.[Result] The results showed that,compared with non-planted group,planting F.arundinacea improved soil physical and chemical properties,increased soil fertility,augmented soil enzymatic activities.[Conclusion] The activity of urease was most sensitive to environmental changes,which could be perferentially used as the monitoring index of evaluating effects of phytoremediation on copper tailings contaminated soils.
