| 摘 要： | 对5个典型的堆肥或施用猪粪尿的农田土壤重金属垂直分布进行了研究。结果显示猪粪的施用可以增加土壤中有机质的含量并使土壤pH值升高。且土壤深度的增加与pH值的升高表现为极显著正相关（p〈0.01）。施用猪粪土壤中Cd和Zn在不同深度土层中呈“峰”型分布．而Cu在不同深度土层中表现为上部富集。Cu，Zn，Cd在农田土壤系统下的迁移能力如下：Cd〉Zn〉Cu。重金属的迁移是个复杂的过程，不但与土壤pH值和有机质含量有关．而且还受其他因素控制。 |
| 关 键 词： | 猪粪 重金属 污染 垂直分布 迁移机制 |

| Abstract: | An inventory of profile distribution of heavy metals in the farmland in which swine manure was applied is presented.The swine manure can increase the organic matter and pH in the soil and the increase of pH is in right proportion to the increase of soil depth(P<0.01).There is a wave crest in profile of concentration of Cd and Zn.Concentration distribution of Cu is top enrichment in profile.The transfer abilities of Cu,Cd and Zn are in the following sequence: Cd>Zn>Cu.From the correlative analysis of depth,pH,organic matter and the concentration of heavy metals we can conclude that the transfer mechanism of heavy metals is complicated. |
| Keywords: | swine manure heavy metals pollution profile distribution transfer mechanism |
