| 摘 要： | 根据石家庄污灌区土壤的平面和垂直剖面土壤样品中As含量数据,制作了As分布图,总结当地As元素分布特征。结果表明:石家庄污灌区内表层和深层土壤中As的分布都受到强烈的外源影响:表层As的分布受到污水排放源位置的控制,深层土壤也受纳了从上层向下迁移的外源As,在表层和深层都形成了若干高值区,各高值区具有独立成因;垂向分布上As主要富集在深部粘土层。

| Abstract: | Based on content of As in soil samples collected from the plane and vertical section of Shijiazhuang sewage irrigation area,the authors compiled the As distribution map and summarized characteristics of As distribution.The results show that,in both topsoil and deep soil,As distribution is affected by outside materials,As in topsoil is controlled by the position of wastewater fountainhead,deep soil accepts As which migrates from topsoil,and As high value areas are solely formed in topsoil and deep soil.In ve... |
