| 摘 要： | 根据物质收支平衡，考虑了土壤生态条件、元素在土壤中的动态变化，应用土壤环境容量数学模型估算了污灌区重金属的最大污灌年限。从环境效应、生态效应考虎，预测污灌区的最大允许污灌年限为６０年。污灌区年控制容量随污灌年限增加而减少，利用污灌指数评价法预测了污灌区重金属污染的情况。其结果与环境容量模型中最大污灌年限的结果相一致。

| Abstract: | Based on the material budget balance, ecological condition and geochemi-cal change of elements in the soil are studied ; the mathematic model of environmental capacity was used to calculate the maximum period of metals in waste water irrigated area. In consideration of environmental and ecological effect, the maximum period is 60 years for waste water irrigation. The controlled capacity decreases with years increasing. The pollution index method is used to predict the metal pollution degree in waste water irrigated area. The result agrees with the maximum period of metal pollution in waste water irrigated area. |
