| Abstract: | 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. |
