摘要
采用污染物平均负荷系数分析法和污染物Separman秩相关系数分析法,对香格里拉县城区2008～2011年5a环境空气污染特征及其变化趋势进行分析,得出影响香格里拉县城大气环境质量的主要污染物是可吸入颗粒物。可吸入颗粒物呈下降趋势,二氧化硫呈上升趋势,二氧化氮变化平稳。
The air pollution characteristics and its development trend in the urban Shangri-la from 2008 -2011 is analyzed in this article, by using the pollutant average load factor analysis and the pollutant Separman rank correla- tion coefficient analysis. It shows that its major air pollutant is inhalable particulate matter which presents a decli- ning trend. However, the sulfur dioxide goes upward and the nitrogen dioxide stays stable.
