| 摘要: |
| 模拟不同程度的铜、镉、铅、氟污染,测定了苏联生草灰化土和潜育泥炭土、中国湖北的红壤和黄棕壤、北京浅色草甸土、山西碳酸盐褐土对上述污染元素的缓冲性。结论:有机质含量高、阳离子代换量高、碳酸钙含量高、质地粘重、中性的北方土壤对重金属的缓冲性强,对氟的缓冲性弱;富含氧化铁、铝的酸性南方土壤,对氟缓冲性较强,而对重金属缓冲性最弱。分析了影响土壤对该污染元素的缓冲性的因素。 |

| Abstract: |
| To study the tolerance of soils to the pollutant elements,the buffer capacity of soils was estimated by treating soils with variable doage of Cu,Pb,Cd and F.The studied soils included podsolic and glei-peat soils collected in USSR,lateritic and yellow brown soils in Hubei Province,light-coloured mea- dow soil in Beijing and carbonate cinnamon soil in Shangxi Province.It was found that soils possessing strong buffer capacity to heavy metals but weak to flou- rine are neutral,rich in organic matter,high in ex... |
