| 摘 要： | 为长沙-株州-湘潭(长株潭)城市群的资源节约型和环境友好型实验区规划和建设特别是环境污染预警方面提供依据,在长沙-株洲-湘潭地区采集土壤样品60个,用聚类分析和相关分析方法对重金属Cd、Cr、Cu、Ni、Pb和Zn的空间分布特征、来源及污染程度进行分析。结果表明,长沙-株州-湘潭城市群土壤中Cd、Cr、Cu、Ni、Pb和Zn的平均含量分别为4.1mg/kg、59.8mg/kg、59.4mg/kg、29.9mg/kg、100.4mg/kg和281.5mg/kg。除Cu外,均超过该区域内的土壤背景值,Cd和Zn分别超标7.8倍和4.7倍,28.3%的样点处于重污染级;Cd、Cu、Ni、Pb、Zn两两之间均存在显著的相关性;长株潭城市群土壤的重金属污染,尤其是Cd污染的潜在风险应引起足够的关注。
