| 近年来土壤污染问题日益严峻，特别是土壤中重金属污染对土壤肥力、植物生长都有着极大的威胁，为了了解pH值对土壤重金属污染的影响及提高测定的准确性，本文系统地分析了土壤pH值与重金属污染物之间的关系，分别讨论了土壤pH值对重金属污染物存在形态、转化迁移及污染治理三方面的影响，并针对土壤pH值测定过程中的影响因素，提出了相应的测定条件及操作方法以保证土壤pH值的准确测定。结果表明，土壤pH值对重金属存在形态、转化迁移及污染治理都有着极大的影响，是土壤重金属污染的重要影响因素，为重金属污染土壤的筛选、判断及后期治理提供参考。 |
| 英文摘要: |
| The problem of the soil pollution, especially the heavy-metal contamination, is increasingly be more serious in recent years. The heavy-metal contamination not only poses a great threat on soil fertility and plant growth, but also endangers human health. In order to figure out the influence of soil pH on heavy-metal contamination and improve the accuracy of measurement, this paper systematically analyzed the relationship between soil pH and soil heavy-metal contamination. The existing form, transformation and pollution treatment of heavy-metal contamination were discussed, respectively. Furthermore, the corresponding determination conditions and operation methods to ensure the accurate determination of soil pH were put forward. The results showed that soil pH had a great impact on the existing form, transformation and pollution treatment of the heavy-metal, which was an influential factor of heavy-metal contamination by providing references for the screening, judgment and subsequent treatment of heavy-metal contaminated soil. |
