邢台地区农田土壤重金属污染测评模型研究

Study on the Evaluation Model of Heavy Metal Pollution in Farmland Soil in XingtaiArea

农田是农产品的主要生产基地,农田土壤质量不仅决定着农产品的品质和产量,还对消费者的身体健康有重要的影响。在分析邢台地区农田土壤重金属污染源的基础上,利用综合指数评价法建立邢台地区农田土壤重金属污染测评模型,利用熵值法确定测评模型的权重,分析得出研究区域的农田土壤重金属污染程度,依此得出治理邢台地区农田土壤重金属污染的最优方案。

Farmland is the main production base of agricultural and sideline products.The quality of farmland soil not only determines the quality and yield of agricultural products,but also has an important impact on the health of residents.Based on the analysis of farmland soil heavy metal pollution sources in Xingtai area,this study uses comprehensive index evaluation method to establish farmland soil heavy metal pollution evaluation model in Xingtai area,uses entropy method to determine the weight of the evaluation model,and analyzes the degree of farmland soil heavy metal pollution in the study area.Based on this,the optimal plan for the treatment of heavy metal pollution in farmland soil in Xingtai area is drawn.
