昌吉市2016年冬春季多次出现雾霾天气,针对昌吉市2016年采暖期和非采暖期PM_(2.5)和PM_(10)的浓度变化特征进行分析,结果显示:2016年全年空气质量在二级以上达标的天数为267 d,占72.9%,未达标天数占26.6%;采暖期PM_(2.5)和PM_(10)的质量浓度显著高于非采暖期,平均值是非采暖期的5.6倍和3.1倍,2月浓度值达到最高;采暖期间的首要污染物质为PM_(2.5),比例最高占66.3%,PM_(10)次之(占33.7%),非采暖期间污染物质PM_(10)占37.4%,PM_(2.5)占8.1%;采暖期间PM_(2.5)在PM_(10)中的比重(60.8%)也高于非采暖期(33.3%)。
Haze weather occurred many times during summer and winter seasons in 2016, according to the analysis of the con-centration of PM2 5 and PM10 during hating period and non - hating period in this yeadays which air quality reached the second grade or above in 2016 was 267, accounting for 72. 9% of the total, while the num-ber of days fail to meet standards reached 26. 6% . The concentration of PM2 5 and PM1.0 during hating period is significantly higher than the non - hating period , with 5. 6 times and 3. 1 times higher than non - heating period , concentration peak ap-peared in february ;PM2 5 is the primary pollutant during hating period with the highest proportion of 66. 3% , while PM2.5 ac-counted for 33. 7% ; During non - hating period , PMW proportion accounted 37. 4% while PM2.5 proportion accounted 8. 1% , and , the proportion of PM2 5 in PM1() during hating period (60 . 8% ) is higher than it during non
