摘　　要：为了研究太原市污水灌溉对土壤有效态元素铜、锌和锰含量的影响,对太原市污水灌溉区(小店区、尖草坪区、晋源区和清徐县)150个土壤样品有效态微量元素铜、锌和锰的含量和分布进行了测定和分析。结果表明,长期污水灌溉导致该区土壤铜、锌和锰的含量均高于文献测定值。有效铜含量晋源区>小店区>清徐县>尖草坪区,分级评价结果均以中等级含量为主;有效锌含量小店区>晋源区>清徐县>尖草坪区,除小店区以低、中级含量为主外,其他3个污灌区均以低等级含量为主;有效锰含量晋源区>清徐县>尖草坪区>小店区,其分级分布情况变异最大,除小店区以低等级含量为主外,其他研究区域有效态锰均以高等级和极高等级含量为主。整体来看,研究区整体缺锌,有效铜含量适中,有效锰含量较高。The purpose of this research is to study the effects of sewage irrigation on the available contents of Cu, Zn and Mn in the areas subject to sewage irrigation in Taiyuan. A total of 150 soil samples were collected from 4 typical sewage irrigation areas（the Districts of Xiaodian, Jiancaoping and Jinyuan, and the County of Qingxu）. The available contents of Cu, Zn and Mn were measured with atomic absorption spectrophotometer. The analytical results showed consistently higher levels of Cu, Zn and Mn than those in recorded in previous literatures, most likely due to long-term application of sewage irrigation in these areas. The distribution level of available contents of Cu in soils was identified as：JinyuanXiaodianQingxuJiancaoping. Hierarchical analysis showed that the Cu concentration was at moderate level in most soil samples. For Zn, the distribution of soil available contents was：XiaodianJinyuanQingxuJiancaoping. It was noted that the Zn content varied from deficient to moderate levels in Xiaodian, while remaining low degree in the rest 3 areas. The available content of Mn was ranked as JinyuanQingxuJiancaopingXiaodian. Soil Mn showed the greatest variations in distribution in Taiyuan, varying from the low level at Xiaodian to high or even extremely high levels in the rest areas. It is summarized that the study areas are generally deficient of Zn, with moderate Cu and high Mn available contents.
