| 摘 要： | 在对开封市惠济河污灌区耕作层土壤污染现状调查的基础上，选取灌区土壤中Pb、Cd、Cr、Cu为评价因子，根据情景预测法估算重金属的累积现速率和累积加速度，建立含量变化预测预警模型，在乐观情景和无突变情景下对土壤中重金属含量变化趋势进行预测；以及在匀速累积模式和加速累积模式下对土壤重金属污染趋势进行预警，提出了应对由污水灌溉造成土壤重金属污染的措施。

Heavy metal Pollution Forecast and Early warning research for Kaifeng sewage irrigation area |
| |
| Abstract: | Abstrct:On the basis of soil pollution investigation for arable layer of Huijihe sewage irrigation, select Pb, Cd, Cr, Cu in irrigated soil for the evaluation factor, estimate the accumulation present rate and cumulative acceleration of heavy metals according to scenario forecasting, establish content change forecast and early warnning models, then predict heavy metals trends in the soil under both optimistic and no mutation scerios; As well as get a warning of soil heavy metal pollution trends in uniform and acelerater accumulation mode,and proposed reponsed measures to soil heavy metal pollution caused by sewage irrigation |
