摘　　要：为了解福建省福州市在大都市进程中,与市民健康息息相关的空气质量,通过对福建农林大学校园、福州旗山森林公园和福州南江滨公园3个区域共11个试验点进行观测,掌握大气颗粒物(TSP、PM10、PM2.5和PM1.0)日变化规律,并监测该区域气象因子与颗粒物的相关性特点。结果表明:3个区域空气质量均为II级以上,其中福建农林大学校园最优,其次为南江滨公园,最后为森林公园;福建农林大学和南江滨公园大气颗粒物呈早晚高、中午低的"双峰单谷"的"V"字型或"U"字型,福州旗山森林公园大气颗粒物浓度的日变化规律是早上稍下降后逐步提高、傍晚后急剧升高;影响以上3个区域大气颗粒物浓度的主要因素分别为校园师生出行及活动、机动车辆尾气及扬尘、湿度及游客人群。气象因子与大气颗粒物浓度的相关性研究显示,风速越小、相对湿度越大、露点温度越高,TSP和PM10浓度越高,温度、风寒指数、热力指数、露点温度和湿球温度越低、相对湿度越大,PM2.5和PM1.0浓度越高。To understand the air quality which is closely related to public health in the progress of urbanization of Fuzhou City, capital of Fujian. The daily variation of atmospheric particulates （TSP, PM10, PM2.5 and PM1.0） concentrations and the correlation with meteorological factors were studied in Fujian Agriculture and Forestry University, Fuzhou Qishan Forest Park and Fuzhou South Riverside Park. The results showed that the air quality of the 3 sites was within level II, among which Fujian Agriculture and Forestry University presented best air quality, followed by Fuzhou South Riverside Park, Fuzhou Qishan Forest Park as last. The atmospheric particulate concentrations in Fujian Agriculture and Forestry University and Fuzhou South Riverside Park were higher in morning and evening but lower at noon, the variation patterns showed as “V” or “U”, whereas it dropped slightly in the morning, but increased gradually after that, and raised rapidly in the evening in Fuzhou Qishan Forest Park. The mainly factors to affect the changes in 3 sites were that teachers and students and activities in campus, exhausted gas and swirling dust of motor vehicles, humidity and visitors respectively. The results of correlation between meteorological factors and atmospheric particulate concentrations revealed that there were high concentrations of TSP and PM10 with small wind speed, high relative humidity and dew-point temperature. And there were high concentrations of PM2.5 and PM1.0 with low temperature, wind chill, Thermal index, dew-point temperature and high relative humidity.
