此文通过对广州市 1998 年～2005 年的相关环境数据与经济数据的分析，发现工业二氧化硫的排放量与地区生产总值之间符合EKC(环境库兹涅茨曲线)的倒U型特征，而其年日均值浓度与地区生产总值之间则呈倒N型关系。除此之外，其他大气污染物，如工业粉尘排放总量，工业烟尘排放总量，降尘量以及一氧化碳的浓度均是随着地区生产总值的增长而降低的。各种大气污染物在现阶段，均随着第二产业占地区生产总值比重的增长而增长，随着污染物去除比重的提高而降低，随着设备数的增加而增长。 研究还发现，影响大气污染最重要的因素是政府在治理污染上的投入。而广州市政府相当重视环境污染治理，并取得了不错的成绩，近几年来大气污染各项指标均达到了国家标准甚至高出许多。

This paper analyses partial environment and cconomical data of Guangzhou from 1998 to 2005. It finds that an upside-down U-shaped EKC curve really exists between the emission of industrial SO2 and the gross municipal product. But the relationship between everyday average concentration and the gross municipal product is like an upside-down U-shaped EKC curve. And other air pollutants decrease when gross product goes up. All air pollutants increase when the industrial rationses, reduce when the ratio of eliminated pollutants augments, and go up when the number of equipment increases in latest years. This research also finds that the most important factor to influence air pollution is government's treatment.The municipal government of Guangzhou attaches importance to itand gains it's reward,that is every index of air pollution in Guangzhou accords with the national standard, even much better than it.
