阿图什市空气污染与空气质量及影响因素分析
|
摘要
本文通过对阿图什市空气质量现状分析,得出阿图什市空气质量级别和主要污染方式,沙尘暴对阿图什市空气质量影响分析;阐述沙尘发生气象条件,特大沙尘暴事件,气候变化和人类活动对沙尘气溶胶影响等。结果表明:阿图什市空气质量达Ⅰ、Ⅱ级日数约占全年66.82%,其中Ⅲ级日数则占全年23.59%,Ⅳ、Ⅴ级日数则占9.64%。空气质量达到及好于二级天数是230天。与往年相比,阿图什市空气质量明显下降,这跟沙尘天气及沙尘气溶胶有关。
Based on the analysis of the air quality in Atushi city, this paper concludes the air quality level and main pollution methods in Atushi city, analyzes the impact of dust storms on Atushi air quality, describes the meteorological conditions of sandstorms, and major dust storm events. The impact of climate change and human activities on dust aerosols, etc. The results show that: Atushi City air quality I, II days accounted for about 66.82% of the year, of which the third grade days account for 23.59% of the year, and then is IV, The number of days in the V class accounted for 9.64%. The air quality reached and was better than the second day was 230 days. Compared with previous years, the air quality of Atushi City has dropped significantly. This is related to dust weather and dust aerosols.
