摘要
在开封市不同功能区布设10个土壤采样点,分别于1994年和2006年在同地点采集表层(0~15 cm)样品,用国家标准方法测定土壤As、Pb、Cd和Hg含量,用地积累指数法开展重金属污染评价。结果表明:(1)土壤Cd、Hg富集明显,是主要污染因子。土壤Cd主要来自开封炼锌厂和其他化工企业的"三废"物质,Hg主要来自燃煤废气。(2)郊区农田转变为城市用地后,土壤重金属污染程度有加重趋势;城市土地利用强度下降及管理水平提高可有效减轻土壤重金属污染;同一宗地的权属变化也会导致土壤重金属污染程度的变化。(3)随着城市经济的快速发展,城市土壤重金属的污染状况总体上呈加重趋势,土壤重金属平均地积累指数由1994年的0.98上升至2006年的1.31。
