Popis: China national air quality monitoring network has become the core data source for air quality assessment and management in China. However, during network construction, the significant change in numbers of monitoring sites with time is easily ignored, which brings uncertainty to air quality assessments. This study aims to analyze the impact of change in numbers of stations on national and regional air quality assessments in China during 2013-18. The results indicate that the change in numbers of stations has different impacts on fine particulate matter (PM中国国家环境空气质量监测网已成为中国空气质量评估和管理的核心数据来源. 在监测网的早期建设过程中, 监测站点数量随时间推移发生了显著变化, 这种变化会给空气质量长期趋势评估带来不确定性. 为了了解这种不确定性, 本研究基于2013年监测网站点(SON)和各年实际已有监测网站点(DON), 分别计算了2013--18年间全国和区域细颗粒物(PM
