| 摘 要： | 通过土柱模拟实验,分析了再生水灌溉对土壤pH、电导率(EC)、有机质、CaCO3水平及4种重金属(Zn、Cd、Cu、As)的形态和分布的影响,探讨了再生水灌溉对土壤中重金属形态稳定性的影响.结果表明,和地下水灌溉(清灌)相比,再生水灌溉(污灌)使表层土中有机质质量分数由0.06％增加到0.32％,pH降低了0.4个单位... |

| Abstract: | Batch soil column experiments was conducted to study the effects of reclaimed water irrigation on pH,electrical conductivity(EC),organic material(OM),CaCO3 levels of soil;the variation of morphology,distribution and stability of heavy metals(Zn,Cd,Cu,As) in soil during reclaimed water irrigation were also discussed in the paper.Compared with the groundwater irrigation,reclaimed water irrigation increased the OM of surface layer soil from 0.06%(mass ratio) to 0.32%,while decreased CaCO3 content by 52.7%;pH v... |
| Keywords: | reclaimed water irrigation soil column heavy metal morphology |
