摘要
以长春市7个功能区,30个采样点土壤为研究对象,研究城市土壤中Pb含量、化学形态与土壤物理化学性质的关系。结果发现:长春市土壤重金属Pb污染严重,主要以残渣态和有机结合态为主。不同功能区Pb含量及化学形态差别很大。土壤物理化学性质对Pb及各种化学形态含量影响程度明显不同,通过逐步回归方法确定主要影响因子,且建立土壤中Pb富集及其化学形态预测模型。
Thirty soil samples from 7 domains of Changchun City were analyzed for total concentration,chemical speciation and relationships between them and physicochemical properties of soil.The results showed that urban soils were seriously polluted with Pb,and the Pb was dominated by residual and organic speciation.The contents and chemical speciation of the different domains were obviously different. The different physicochemical parameters had different influences on the Pb content and chemical speciation.The pri...
