用模糊贴近度方法评价土壤重金属污染程度

Evaluation on Polluted Degree by Heavy Metal in Soils with fuzzy Approach Degree Evaluation Method

分析了模糊贴近度方法用于土壤环境质量评价的基本步骤,并以贵州省遵义市环境质量评价为实例,探讨了模糊贴近度方法在土壤环境质量评价中的应用。结果表明,基于模糊贴近度的土壤环境质量评价原理直观、客观,计算方法简单,能较完整地反映土壤环境质量污染程度,是一种实用而准确的评价方法。

The basic procedure in regional soil environment quality evaluation based on fuzzy nearness was analyzed.Taking Guizhou Zunyi as an example,the application of fuzzy nearness in soil environment evaluation was discussed.It is shown that the theory of regional soil environment quality evaluation based on fuzzy nearness is easy to be understand and the computation method is simple.This method can make the extent of soil environment pollution more clear.So it is a practical and accurate evaluation method.
