熵权物元分析模型在土壤环境质量评价中的应用

Application of Matter Element Model Based on Entropy Weight to Evaluation of Soil Environment Quality

根据熵权法确定评价指标权重,利用物元分析方法对福州市郊菜区土壤环境质量进行综合评价,评价结果与密切值法、污染损失率法进行对比。结果表明,利用熵权物元分析模型进行土壤环境质量评价是合理可行的,且评价结果具有更高的分辨率。同时本研究为土壤环境质量评价提供了新的思路和方法。

Entropy weight is used to calculate the weight of evaluating indicators,then a matter element model is also adopted to evaluate the environmental quality of vegetables planted soil in Fuzhou suburb.The results are compared with those of the association value and the pollution lost rate method,the results indicate that the matter element model is feasible for evaluating the soil environment quality and has more resolving power.At the same time,the study expands the ideas and methods of the soil environment quality.
