水稻土中镉污染预测模型的建立与验证

Validation and Build of the Cadmium Pollution Prediction Model on the Paddy Soil

以某市为例,在野外调查、采样和实验室分析的基础上,探讨了水稻土中重金属镉来源的因素,并建立了物料平衡。并根据土壤污染主要污染因素大气降尘建立了水稻土中镉污染的预测模型。选取该市某村对所建立的模型进行验证,得到了较好的效果。

With the example of a city,the sources of the Cadmium in paddy soil,and build the material balance based on the outside investigation,sampling and laboratory analysis.The pollution prediction model was built on the paddy soil according to the main factor.Then the model on a village of the city was validated with preferable result.
