| 中文摘要: |
| 【目的】探讨安徽省 Cd、Pb 污染土壤中 pH、Cd 和 Pb 含量特征及其相关性。【方法】按照土壤
重金属元素的测定方法，分析了安徽省 Cd、Pb 污染潮土、红壤、黄褐土、水稻土中 pH、总 Cd、有效态 Cd、
总 Pb 和有效态 Pb 的含量。【结果】安徽省 Cd、Pb 污染潮土、红壤和水稻土中有效态 Pb 与总 Pb 均有极显著
正相关，显著水平分别为 0.685、0.348 和 0.730。红壤和水稻土中有效态 Cd 与总 Cd 均有极显著正相关，显著
水平分别为 0.365 和 0.899。潮土中 pH 与有效态 Pb 显著正相关，显著水平为 0.555，红壤中有效态 Cd 与总 Pb
呈极显著正相关，显著水平为 0.352。【结论】4 种土壤类型中红壤的有效态 Cd 和有效态 Pb 含量主要受总 Cd
和总 Pb 的影响；水稻土中的有效态 Cd 和有效态 Pb 主要由其总量决定；潮土中有效态 Pb 含量受总 Pb 和 pH
影响较大。 |

| 【Objective】 The study was to investigate the content characteristics and correlations of pH, Cd
and Pb in Cd and Pb contaminated soils in Anhui Province.【Methods】According to the determination method
of soil heavy metal elements, the contents of pH, total Cd, available Cd, total Pb and available Pb in the Cd and Pb
contaminated alluvial soil, red soil, yellow cinnamon soil and paddy soil in Anhui Province were analyzed.【Results】
The results showed that there was a significant positive correlation between the available Pb and the total Pb in Cd and Pb
contaminated alluvial soil, red soil and paddy soil in Anhui Province, with significant levels of 0.685, 0.348 and 0.730,
respectively. There was a significant positive correlation between available Cd and total Cd in red soil and paddy soil, with
significant levels of 0.365 and 0.899, respectively. There was a significant positive correlation between pH and available
Pb in alluvial soil, with a significant level of 0.555. There was also a significant positive correlation between available Cd
and total Pb in red soil, with a significant level of 0.352.【Conclusion】Among the four types of tested soil, the contents
of available Cd and available Pb of red soil were mainly affected by total Cd and total Pb. The available Cd and available
Pb in paddy soil were mainly determined by their total amount. The content of available Pb in alluvial soil was greatly
affected by the total Pb and pH. |
