摘要
在深入研究灰色理论的基础上,对传统关联分析模型做了两点修正,先是利用参考点简化了模型的计算公式,再根据各污染物排放贡献率的不同确定了各级权重系数。利用此模型准确反映了杭州市经济技术开发区2003年环境空气质量综合等级为Ⅲ级,并对不同样本的空气质量进行了优劣性比较,进一步分析了该区因子与因子及因子与总量之间的相关关联程度,确定该区大气主要污染物为PM10。
The author modifies the classical grey relation model to evaluate atmospheric environmental quality, The fast improvement is to predigest the model＇s formula using the reference point, The second modification is to assign the weight ratio based on the contribution of different pollutants. It has been used in valuing atmospheric environmental quality of Hangzhou Economic Development Area in 2003, which indicates the comprehensive grade is Ⅲ , This model can be used not only in comparing the atmospheric environmental quality of different sample areas, but also in analyzing the correlation degrees among the PM10, SO2 and NO2. Furthermore, PM10 is the chiefly pollutant of this area in 2003, which is indicated by this model.
