| Abstract: | In order to improve the atmospheric environment,based on the major air pollution monitoring data of Urumqi city during 2004～2010,the air quality of Urumqi city was assessed using atmospheric pollution composite index and its development trend was forecasted using Spearman rank correlation coefficient.The results showed that the air quality of Urumqi city was lightly polluted and the main pollutants are SO2 and PM10.The concentration of NO2 and PM10 displayed up trend,and that of SO2 showed downtrend but not significantly. |
