摘要
基于青藏高原环境空气质量保护的重要性,选取位于高原东部的康定市作为研究对象,通过获取2020年1月1日~2023年6月30日环境空气主要污染物数据,经数据透视表处理给出分季度24小时浓度均值变化趋势,结合Pearson相关系数分析得出,康定市首要污染物为NO_(2)和O_(3)的原因主要受城市移动源排放和光化学反应影响,同时,移动源排放也是CO和颗粒物(PM_(10)和PM_(2.5))浓度时段性协同升高的主要原因。
Based on the importance of environmental air quality protection in Qinghai-Tibet Plateau,Kangding city,located in the eastern part of the plateau,was selected as the research object.The data of major environmental air pollutants from January 1,2020 to June 30,2023 were obtained through Pivot Table processing,and the mean variation trend of 24-hour concentrations in each quarter was presented.The reason why the primary pollutants in Kangding were NO_(2)and O_(3)was mainly influenced by mobile source discharge and photochemical reaction.Meanwhile,mobile source discharge was also the main reason for the coordinated increase in the concentrations of CO and particles(PM_(10)and PM_(2.5))over a certain period.
