川西地区空气污染特征及气象影响因素分析
|
摘要
为研究2015-2017年川西地区大气污染特征及其与气象因素的关系,对大气污染监测数据和地面气象观测资料进行分析,结果表明:2015-2017年川西地区空气质量指数减小,空气质量变好;细颗粒物与可吸入颗粒物污染在冬季-春季呈单峰型分布,臭氧污染在春季-秋季呈双峰型分布;可吸入颗粒物的一级超标率最大,细颗粒物的二级超标率最大;风速、3小时变压、温度与空气质量指数呈负相关;北风、东北风、西北风为主导风,污染日数与风向分布趋势一致。
In order to study the characteristics of atmospheric pollution and its relationship with meteorological factors in western Sichuan during 2015-2017, air pollution monitoring data and ground meteorological observation data were analyzed. The results show that the air quality index has decreased and air quality is better in western Sichuan region during 2015-2017; the pollution of particulate matter and inhalable particulate matter show a single peak distribution from winter to spring. Ozone pollution show a bimodal distribution from spring to autumn; the first-order over-standard rate of inhalable particles is the largest, and the second-level over-standard rate of fine-particles is the largest; wind speed, 3 hours of pressure change, temperature and air quality index are negatively correlated; north wind, north-east wind, and north-west wind are dominant wind, the number of pollution days is consistent with the trend of wind direction.
