摘　　要：利用臭氧检测仪(Ozone Monitoring Instrument,OMI)反演的甲醛柱浓度数据(OMHCHO_003),选取山东省日照市作为东部典型沿海城市,分析其2014~2020年甲醛柱浓度的时空变化特征和影响因素,发现其甲醛柱浓度空间分布呈现季节性特征,夏季高值是其他季节平均值的1.5倍左右,且夏季高值呈带状分布于西北部莒县境内。日照市7年间全境甲醛柱浓度呈现显著增长,其中东港区增幅达到0.20×10^(15) mol cm^(−2) a^(−1),该增幅与高人为源排放的京津冀地区的甲醛柱浓度增幅趋于一致,并且日照市甲醛柱浓度与森林覆盖、机动车保有量、工业能源消耗量存在显著相关性。为进一步探究山东省日照市在中国东部沿海城市中甲醛柱浓度变化,选取共32个中国东部沿海城市(对应六大沿海省份辽宁、山东、江苏、浙江、福建和广东省),对比分析其2014~2020年夏季甲醛柱浓度含量和变化趋势,其中山东省日照市甲醛柱浓度7年间增幅在32个中国东部沿海城市中排名第一。本研究对山东省日照市的甲醛防控部署有非常好的应用和参考,并很好地弥补了中国东部沿海城市甲醛柱浓度研究的空白。Using the Ozone Monitoring Instrument(OMI)derived satellite data(OMHCHO_003),Rizhao in Shandong Province was chosen as a typical eastern coastal city to investigate the characteristics of its vertical column density(VCD)changing trends for formaldehyde from 2014 to 2020.The spatial distribution of VCD for formaldehyde presents an obvious seasonal characteristic.The high value of VCD for formaldehyde in the summer is about 1.5 times the average value in other seasons.In summer,the high VCD value for formaldehyde is mainly located in Ju County,northwest of Rizhao.The VCD for formaldehyde in Rizhao has increased significantly over the last seven years.Moreover,its increasing rate in the Donggang District reached 0.20×10^(15) mol cm^(−2) a^(−1),consistent with the North China Plain’s high anthropogenic emissions.The rising trend for formaldehyde correlates with the forest cover,the number of motor vehicles,and industrial energy consumption.The increasing trend in Rizhao is the largest among the chosen 32 coastal cities(covering Liaoning,Shandong,Jiangsu,Zhejiang,Fujian,and Guangdong coastal provinces).This study is an excellent application and reference for the deployment of formaldehyde prevention and control in Rizhao,and it fills the gap in the formaldehyde VCD study in coastal cities in eastern China.
