摘　　要：湘江流域土壤重金属污染已成为流域内最重要的环境问题之一,其中有色金属矿区土壤Cd污染对农产品的安全生产具有较高的潜在风险。在分析湘江流域矿区土壤Cd污染现状和成因的基础上,总结了近年来湘江流域矿区Cd污染土壤的修复实践,比较了不同Cd污染程度的安全高效利用措施,并对流域内未来的土壤修复和综合利用工作提出了展望。Heavy metal contamination has became one of the most important environmental problems in Xiang river basin, of those metals, Cd contamination in nonferrous metal mining area has potentially high risk for the safe production of agricultural products. Based on the analysis of status quo and courses of Cd contamination in mining area in Xiang river basin, this paper summarized the practices of remediating Cd contaminated soils in recent years, compared safe and effective utilization measures for Cd contaminated soils in different contaminated grades, and put forward prospects for the future works that remediation and comprehensive utilization of Cd contaminated soils in nfining area in Xiang river basin.
