环境科学与工程-福建省大气中CO污染特征研究论文

摘 要一氧化碳（CO）是全球碳循环中的一种重要气体，是大气主要污染物之一。针对当前大气环境污染问题，以福建省为研究对象，对福建省 2015-2019 年大气污染物中的 CO 进行综合分析。分析结果表明，CO 表现出明显的月变化特征，整体水平上，峰值一般出现在 1 月份或 12 月份，6-8 月为 CO 质量浓度的谷值；春、冬季较高，夏、秋季较低的季节性特征，此外，还对年际变化趋势、空间变化特点以及对 CO 浓度影响因素进行了分析。本研究可为更全面更客观地反映我省 CO 污染状况，对 CO 污染的监测及预测有重要意义，同时为福建省今后的大气污染防治工作提供参考。 关键词：大气污染；CO；污染特征；影响因素AbstractCarbon monoxide (CO) is an important gas in the global carbon cycle and one of the main pollutants in the atmosphere. In view of the current atmospheric pollution problems, Fujian Province was taken as the research object to conduct a comprehensive analysis of CO in Fujian Province's air pollutants from 2015 to 2019. The analysis results show that CO exhibits obvious monthly variation characteristics. On the whole level, the peak generally appears in January or December, and the valley of CO mass concentration is from June to August; it is higher in spring and winter, and lower in summer and autumn. Seasonal characteristics, in addition, the interannual change trend, the characteristics of spatial change and the factors affecting the CO concentration were also analyzed. This study can provide a more comprehensive and objective reflection of the CO pollution situation in our province, and is of great significance for the monitoring and prediction of CO pollution. At the same time, it can provide a reference for future air pollution prevention and control in Fujian Province.Key words：air pollution；CO；pollution characteristics；influencing factors目 录1 引 言........................................................
