摘 要: 文章运用灰色系统理论中的关联分析方法分析了与广州大气NOx浓度有关的几个因素。结果表明,广州市区平均车流量 和道路面积是影响NOx浓度水平的两个最主要因素。文章用灰色GM(1,1)模型预测了NOx浓度的变化趋势,最后提出了控制和治理 NOx污染的相应对策。 Several affected factors of atmospheric NOx concentration have been analyzed by applying theory and relation method of grey-system. The result showed that the hourly average vehicle flow and the area of motor road in Guangzhou proper were two major factors which affected atmospheric NOx concentration. Adopting grey model GM (1,1) to forecast the variation of NOx concentration, and relevant countermeasures to control and eliminate NOx pollution were put forward.
