我们通过整理2004-2013年十年间《中国环境统计年鉴》中的各地区废气排放情况发现各省主要空气污染物为二氧化硫和烟尘排放,绝大多数省的工业排放量远远超过生活。各省之间排放量存在较大差异,其中山东、山西、河北、河南等省的排放量为全国各省之最。 于是选取我国十八个典型省市为研究对象,分析各省SO2和烟尘排放里生活排放和工业排放的比较情况,从图中通过机动车的烟尘排放量可以看出最近几年空气污染有所加重。 Based on 10 volumes of “China Statistical Yearbook on Environment” (from 2004 to 2013), we sorted out data of emissions in various regions. The result shows that sulfur dioxide (SO2 ) and smoke and ashes are the main source of air pollution. In most provinces, emissions in industrial sector far exceeds that generated in daily life. Also, amount of emissions varies among different regions, with Shandong, Shanxi, Hebei and Henan provinces emiting more exhaust gas than any other provinces. Eighteen provinces and cities that are typical of our national emission are thereby selected as research objects to analyze and compare emissions of SO2 and smoke between industrial sector and that generated in daily life. It is suggested that the data of motor vehicle emissions gave a visual representation showing that aggravation of air pollution has flattened out in recent years.
