| 摘 要： | 以土壤生态为研究中心,以污水灌溉为研究对象,基于草甸棕壤基本性质,通过污染现状调查,敏感作物盆栽试验,依据土壤-植物、土壤-微生物、土壤-水体系各项指标,提出了汞、镉、铅、砷、铬的土壤临界含量。结合田间物质平衡试验,建立土壤容量数学模型,综合计算出草甸棕壤五种重金属环境容量。根据土壤容量,在污灌地区,制定了水质标准和污泥施用量,并进行了土壤环境的预测。

| Abstract: | The criteria of Hg, Cd, Pb, As and Cr contents in a meadow brown soil were studied based on investigation of the wastewater irrigated soil as well as on pot experiments. The environmental capacities of the soil for the heavy metals were calculated using a capacity model, according to which a prediction of heavy metals accumulation in the wastewater irrigated soil was made and suggested quality standards for irrigation and sludge application were proposed. |
