摘 要近年来，大气污染环境问题逐渐加剧，为清楚了解福建省大气中 SO2污染特征，本研究基于福建省 2015-2019 年各地市 SO2浓度数据，阐述其时空变化特征，并将 SO2月浓度同相应气象因子降水量、气温作双坐标图分析，探讨气象因素的对污染物浓度的影响。主要结论有：2015-2019 年，福建省 SO2月浓度曲线整体呈“U”型变化特征，具有季节性差异，冬春季节浓度普遍高于夏秋季节，随着年份的增长，SO2浓度水平降低；SO2浓度与降水量、气温呈显著负相关；福建省 SO2浓度变化具有区域性特点，沿海城市污染物浓度较低，而山区城市污染物浓度较高；利用《环境空气质量标准》(GB3095 -2012)评价，福建省九地市 2015-2019 年期间二氧化硫污染物浓度年均值均达到国家一级标准。关键词：福建省；二氧化硫污染；时空分布；气象因素AbstractIn recent years,the environmental problem of atmospheric pollution has graduallyintensified,in order to clearly understand the characteristics of SO2 pollution in the at-mosphere of Fujian Province, this study is based on the data of SO2 concentration inv-arious cities in Fujian Province from 2015 to 2019,to elaborate its spatio-temporal characteristics,and to analyze the monthly concentration of SO2 with the correspondingmeteorological factors precipitation and temperature as a double-coordinate graph to explore the influence of meteorological factors on pollutant concentration.The mainconclusions are: from 2015 to 2019, the monthly SO2 concentration curve in Fujian Province is characterized by a "U"-shaped change,with seasonal differences;the winterand spring seasons are generally higher than the summer and autumn seasons, with theincrease of the year,the level of SO2 concentration decreases;SO2 concentration is sign-ificantly negatively correlated with precipitation and temperature;the change of SO2 concentration in Fujian Province has regional characteristics,with lower concentrationsof pollutants in coastal cities and higher concentrations ...
