摘要
近几年来,我国经济发展迅速,一跃成为世界一大经济强国。但是随之牺牲的是空气质量下降,环境污染越来越严重。为了了解我国城市废气中主要污染物的排放情况和污染来源,我选取了我国几个主要城市中工业二氧化硫排放量、工业氮氧排放量、工业烟(粉)尘排放量、生活二氧化碳排放量、生活氮氧化物排放量和生活烟尘排放量几个指标对这个问题进行分析。
In recent years, China’s economy has developed rapidly and has become a major economic power in the world. But the sacrifice is the deterioration of air quality and the increasingly serious environmental pollution. In order to understand the emission situation and sources of major pollutants in urban exhaust gases in China, I selected the industrial sulfur dioxide emissions, industrial nitrogen and oxygen emissions, industrial smoke(powder) dust emissions, domestic carbon dioxide emissions, domestic nitrogen oxides emissions and domestic smoke and dust emissions from several major cities in China. An indicator is used to analyze the problem.
