摘要
建立了利用集对分析法进行土壤环境质量评价的模型,以上海市郊的评价区域土壤环境中重金属含量为例,研究了10个区域土壤重金属污染的状况。实例应用表明,该评价方法与模糊综合评价法的评价结果基本一致。集对评价模型结构严谨,评价结果合理、精细、分辨率高,为区域土壤重金属污染评价提供了一种有效的评价方法。
A method of evaluating regional soil environmental quality was presented by means of set pair analysis(SPA) method.The model was used to assess 10 regional agricultural soil polluting levels of Shanghai suburbs with more satisfactory results compared with the fuzzy comprehensive method.This model was perfect.The evaluating result was more reasonable and its resolving power was higher.Thus,a simple and effective evaluation method was provided for evaluation of regional soil pollution from heavy metals.
