摘　　要：为探究长江三角洲地区大气污染物时空分布特征,以2014年至2021年中国环境监测总站公开数据为基础,探究大气中六种主要污染物(二氧化硫(SO_(2))、二氧化氮(NO_(2))、一氧化碳(CO)、臭氧(O_(3))、PM_(2.5)以及PM_(10))分布特征以及变化规律。结果表明,长三角地区大气污染物表现出季节分布特征明显、年变化趋势不同以及时空分布特征多样的特点。PM_(2.5)、PM_(10)和NO_(2)呈现先下降后上升的趋势,O_(3)浓度逐年上升,而SO_(2)和CO浓度相对稳定。需要重点关注冬季和夏季的污染防治工作,并针对不同区域的特点采取有针对性的污染物治理措施。此研究结果可为区域性空气污染物治理提供一定的参考借鉴意义。Based on the publicly available data from the China Environmental Monitoring Station from 2014 to 2021,this study aims to explore the spatial-temporal distribution characteristics and trends of six major air pollutants(sulfur dioxide(SO_(2)),nitrogen dioxide(NO_(2)),carbon monoxide(CO),ozone(O_(3)),PM_(2.5),and PM_(10))in the Yangtze River Delta region.The results indicate distinct seasonal variations,different annual trends,and diverse spatial patterns of air pollutants in the region.PM_(2.5),PM_(10),and NO_(2)showed a decreasing trend followed by an increasing trend,while O_(3)concentrations increased over the years.SO_(2)and CO concentrations remained relatively stable.It is crucial to focus on pollution prevention and control measures,especially during winter and summer seasons,and implement targeted strategies based on the specific characteristics of different areas.These findings provide valuable insights for regional air pollution management.
