| 中文摘要: |
| 土壤重金属污染是当今重要的世界性环境问题之一，尤其近年来不断出现的农产品重金属超标问题与农田土壤重金属污染程度密切相关。因此，选择合理的模型和方法对农田土壤中重金属污染状况进行评价，这对于环境和健康问题显得尤为重要。本文综述了国内外常用于农田土壤重金属评价的传统指数模型和以指数模型为基础而延伸出来的一些评价方法，介绍了基于GIS技术、土壤重金属形态分析以及以农产品质量安全为基础的评价模型，分析了主要评价模型和方法的优缺点，提出了农田土壤重金属污染评价研究的方向。 |
| 英文摘要: |
| The Heavy metal pollution in soil is one of the most important environmental problems in the world. In recent years, excessive heavy metal contents in agricultural products was closely related to the heavy metal pollution in farmland soils. Therefore, the selection of reasonable models and methods to evaluate the status of heavy metal pollution in farmland soils is particularly important for recognizing environmental and health issues. This paper reviews traditional index models commonly used in the evaluation of heavy metals in farmland soils worldwide and some evaluation methods based on the exponential model. This paper also introduces evaluation models based on GIS technology, soil heavy metal speciation analysis and agricultural product quality and safety. It analyzes advantages and disadvantages of main evaluation models and methods and proposes the research direction of heavy metal pollution assessment in farmland soils. |
