Abstract:

基于珠三角地区98个同点位土样,探讨了土壤Cd含量的时空分布特征及风险管理策略。研究表明,两批次土壤Cd含量富集程度均很高,土壤Cd平均含量C2001和C2007均为0.28mg/kg,是广东省土壤背景值的5倍;两者均值多重比较表明,Cd的均值变化达到显著水平。土壤Cd的变异系数分别为0.83和0.72,暗示了Cd主要来源于人为成因。经估算,土壤Cd区域性年均累积速率KC2007-C2001、KC2012-C2007分别为0.016和0.014mg/kg。采用"时空模式"和"空时模式"模型预测土壤Cd含量的时空分布态势,在时间序列资料较少的情形下,"时空模式"预测结果较稳健。2020年研究区大部分区域土壤Cd有污染,未来的风险管理应对无污染区域采取预防策略;对有污染区域采取控制策略;对重污染区域采取修复策略。
