摘要 针对平原区多目标地球化学调查工作中亟待解决的技术问题,在试验研究资料基础上,本文提出了平原区多目标地球化学调查异常查证及生态效应评价方法。异常查证阶段,首先应用相关关系法确定异常组分的地球化学基准值,而后进行异常分类,确定异常的成因和形成机理,为异常生态效应评价提供理论基础。在异常生态效应评价中,首先要弄清土壤中异常组分全量与其活性组分间的关系,进而探讨土壤和农作物中异常组分的含量关系,最终依据相关标准,评估农作物中重金属元素的含量水平,及其通过食物链对人体健康可能造成的危害。 The paper focuses on the urgent technical issues arising in multi-purpose geochemical survey in plain areas.Based on the data of experimental study, the method for anomaly inspection and ecological appraisal of multi-purpose geochemical survey in plain areas is proposed. In the stage of anomaly inspection, the correlatiom method should be used to determine the geochemical base lines of the anomalous components first, and then classing of anomalies is made to make sure the origin and genetic mechanism of anomalies and provide a theoretical basis for the appraisal of anomaly ecological effect. In the stage of anomaly ecological effect appraisal, it is necessary first to make clear the correlation between the total content of anomalous components and their active components in soil, then to investigate the content correlation between the anomalous components in soil and crops and finally to evaluating the content of heavy metals in crops and their harm to human health through the food chain according to the relevant standards.
