摘要
目的探讨对大气污染程度的综合评价方法。方法应用加权关联度分析对我国11个城市的大气监测数据进行综合评价。结果求出11个城市大气污染程度的加权关联度值,排序结果与TOPSIS法排序结果完全一致,并列出加权关联度值的频数分布,估计回归方程r^=-0.177 9+0.999y,具有非常显著性意义(P<0.001),经合理分档,得出中度污染的城市7个,轻度4个。结论加权关联度分析能直观、定量地、简明地、准确地、清晰地、科学地、全面地反映城市大气污染程度的概貌,适用于城市大气污染程度的综合评价。
Objective To research the comprehensive assessment method of atmospheric pollution. Methods Weighting association analysis was taken to comprehensively evaluate the data of air monitoring in 11 cities in China. Results Values of weighting association of air monitoring in 11 cities were calculated, and the ordering result was in full accord with the result of TOPSIS. The frequency distribution of weighting association showed obvious difference with estimating regression equation of ^↑r = - 0. 177 9 ＋ 0. 999 1y （ P 〈 0.001 ）. There were 7 cities with medium and 4 cities with light atmospheric pollution by reasonable classification. Conclusions Weighting association analysis can show the general picture of city＇s atmospheric pollution directly, quantificationally, concisely and clearly as well as roundly. It is applicable to comprehensive assessment of atmospheric pollution.
