| 摘 要： | 土壤是一个开放体系,尤其城市的土壤污染来源更为广泛,而在土壤的质量评价中,常涉及到大量的复杂现象和多种因素的相互作用,且存在大量的模糊现象和模糊概念。针对这一情况,在成都城区168个土壤样品进行调查和实测后,对主要影响土壤质量的六种重金属污染进行分析,并且在环境地球化学原理的基础上,根据土壤污染分级标准建立了土壤质量的综合评判模型,同时给出了六种重金属的隶属函数。最后在对成都六个城区土壤样本的综合评判中,准确地得出了各城区的土壤污染程度及污染类别。

| Abstract: | An integrated evaluation method based on fuzzy method is introduced in details and applied in environmental geochemistry evaluation.According to fuzzy mathematics and polluted soil classification,an integrated evaluation model of soil quality is established.Meanwhile,subject functions of six heavy metals are also presented.In the course of evaluating the samples of soil in the six districts of Chengdu city,the degree and types of the polluted soil are accurately measured. |
