利用综合污染指数法和空气污染指数法对2012年永川城区环境空气质量现状进行评价，结果表明：2012年永川城区空气综合污染指数为2.25，空气质量保持良好，稳定达到国家二级标准，全年空气质量满足Ⅱ级天数为336天，占全年比例91.8％，污染物中PM10所占负荷比为40％，为首要污染物。月变化规律表明，2012年永川城区环境空气主要污染物月均值均呈现V字型的变化规律，春、冬季较高，夏、秋季较低。同时还与2011年作了对比分析。
利用綜閤汙染指數法和空氣汙染指數法對2012年永川城區環境空氣質量現狀進行評價，結果錶明：2012年永川城區空氣綜閤汙染指數為2.25，空氣質量保持良好，穩定達到國傢二級標準，全年空氣質量滿足Ⅱ級天數為336天，佔全年比例91.8％，汙染物中PM10所佔負荷比為40％，為首要汙染物。月變化規律錶明，2012年永川城區環境空氣主要汙染物月均值均呈現V字型的變化規律，春、鼕季較高，夏、鞦季較低。同時還與2011年作瞭對比分析。

Comprehensive pollution Index and air pollution index were used to assess the environmental air quality of the year of 2012 in urban area of Yongchuan in Chongqing.The results showed that the air comprehensive pollu-tion index was 2.25 indicating that the environmental air quality in urban area of Yongchuan maintain was good. The air quality reached the national secondary standard in 2012.In this year,the number of days of the air quality reached the national secondary standard was almost 336 days,accounted for 9 1.8%of the proportion of the whole year.The primary pollutant was PM10 .Its loading alone was 40%.The monthly variation suggested that the month-ly average value of main pollutant went like a“V”shape seasonally.The monthly average value of the main pollu-tant was higher in spring and winter than that in summer and autumn.Meanwhile,a comparative analysis between the year of 201 1 and 2012 was conducted.
