中文摘要	通过盆栽模拟试验,研究了蜈蚣草(Pteris vittata)生长对其根际铜尾矿土壤酶活性的影响。结果表明,蜈蚣草根际土壤中过氧化氢酶、脲酶、多酚氧化酶和蔗糖酶活性均随着植物的生长而呈现不同程度的升高,其中过氧化氢酶和脲酶活性均与植物生长时间之间呈显著正相关,多酚氧化酶和蔗糖酶活性在植物生长旺盛期达到峰值,分别为对照组的3.59和2.58倍,随后逐渐下降;而磷酸酶活性却随着植物的生长而显著降低。过氧化氢酶、脲酶和磷酸酶活性与蜈蚣草地下部分干质量的相关性大于其地上部分,且5种土壤酶活性与土壤有机质含量之间相关显著。蜈蚣草生长可有效改善根际铜尾矿的基质环境和根际土壤肥力水平,因此,在铜尾矿废弃地恢复实践中具有较大的应用潜力。
英文摘要	Effects of growth of Pteris vittata on enzyme activities in rhizosphere soil of copper mining tailings were studied by means of a pot experiment.Results show that with P.vittata growing,the activities of catalase,urease polyphenoloxidase and invertase increased to a varying extent.The activities of both catalase and urease were significantly positively related to duration of the growth,and the activities of both polyphenoloxidase and invertase peaked during the vigorous growth period of the plant,being approximately 3.59 and 2.58 times as high as that in the control,separately,and then gradually decreased.However,the activity of phosphatase displayed a reverse trend.Compared with the aboveground parts of the plant in dry weight,the underground parts showed a stronger correlation with the activities of catalase,urease and phosphatase,and the activities of the five soil enzymes in the rhizosphere soil were positively related to the content of organic matter.In summary,the growth of P.vittata significantly improved fertility of the rhizosphere soils.Therefore,P.vittata exhibits great potential in remedying deserted copper-minings.
