| 摘 要： | 为了研究矿区不同复垦条件下,复垦土地土壤中有效微量元素与土壤环境的关系,采用实地试验与实验室分析相结合的方法,研究了不同复垦时间和复垦措施条件下土壤有效铜(Cu)、铁(Fe)、锰(Mn)、锌(Zn)4种微量元素有效态含量与土壤环境之间的关系。结果表明,研究区内土壤有效微量元素含量总体属于极低水平;土壤环境整体呈碱性,土壤pH值均在8.5以上,且变异系数属于小变异;土壤有机质无论是在不同恢复年限条件下,还是在不同治理措施条件下,其变异系数均属于高度变异。土壤环境与土壤有效微量元素相关关系分析结果表明,土壤pH值与土壤有效微量元素呈负相关关系,有效锰、有效铜与土壤pH值的相关性较高;土壤有机质与土壤有效微量元素呈正相关关系,其中有效锌、有效铜与土壤有机质含量的相关性较高。 |

| Abstract: | Based on field sampling and laboratory analysis,relationships between soil environment and soil available trace element,including Cu,Fe,Mn,and Zn were studied.Results indicated contents of these 4 soil available trace elements were lower generally.Soil pH value was over 8.5,and the variation coefficient belonged to small variability.Variation coefficient of soil total organic carbon(TOC)under different restoration year and management conditions belonged to higher variability.Analysis of soil environment and soil available trace element indicated that negative correlation was existed between soil pH and available trace element,among which coefficients of Mn and Cu were higher.Positive correlation was existed between soil TOC and soil available trace elements,among which coefficients of Zn and Cu were higher. |
| Keywords: | available trace element soil pH value total organic carbon restoration land |
