摘要	空气污染对人类的健康和环境有重要影响，对空气质量进行管理可以有效预防空气污染对人类健康和环境造成的危害。细微颗粒物(PM2.5)在空气质量数据中对环境质量的影响最大，因此对其防控具有重要意义。由于划分防治区域是实施防控的重要前提，因此文章针对重庆市主城区17个监测站点的PM2.5日均浓度数据，在采用7种插补方法修复PM2.5缺失数据的基础上，分析其时空分布特征，并利用函数型聚类方法(Functional Nonnegative Matrix Factorization,FNMF)合理地划分PM2.5防治区域，进一步分析重庆市不同区域的空气质量特征。研究结果表明，重庆市主城区可划分为3类PM2.5防治区域，且各区域冬季污染严重，空间分布与城区经济发展相关，呈现出由北向南污染愈发严重的趋势。
其他摘要	Air pollution has an important impact on human health and the environment.Air quality management can effectively prevent the harm caused by air pollution to human health and the environment.Fine particulate mat-ter(PM2.5)has the greatest impact on environmental quality in air quality data,so it is of great significance for its prevention and control.Because the division of prevention and control areas is an important prerequisite for the im-plementation of prevention and control,so this article focuses on the daily average concentration data of PM2.5 from 17 monitoring stations in the main urban area of Chongqing.On the basis of using 7 interpolation methods to repair missing PM2.5 data,the spatial-temporal distribution characteristics are analyzed,and Functional Nonnegative Ma-trix Factorization(FNMF)was used to reasonably divide PM2.5 prevention and control areas,and further analyze the air quality characteristics of different regions in Chongqing.The research results indicate that the main urban area of Chongqing can be divided into three types of PM2.5 prevention and control areas,and the pollution in each area is serious in winter,and the spatial distribution is related to the economic development of the urban area,showing a trend of increasing pollution from north to south.
