摘要
利用2014—2015年合肥市颗粒物浓度及气象观测资料,对合肥市颗粒物浓度时空分布特征及其与气象要素的关系进行了分析。结果表明:2015年,合肥市PM10、PM2.5日均浓度均呈现"一增一减"趋势;PM10与PM2.5日均浓度分布季节差异明显,呈现"V"型特征;在空间分布上,PM2.5的浓度主城区高于周边地区,PM10浓度北部整体高于南部;PM10与PM2.5浓度与降水量、相对湿度、风速和风向均有一定相关性。
Based on the monitoring data of ambient air quality and meteorological data in Hefei during2014-2015,the temporal and spatial distribution of particulate matter concentration in Hefei and its relationship with meteorological factors were analyzed.The results indicate:The average daily mass concentrations of PM10and PM2.5in Hefei showed a trend of increasing and decreasing in2015.The seasonal distribution of PM10and PM2.5was significantly different,presenting"V"type features.In the spatial distribution,the mass concentration of PM2.5was higher than that of the surrounding area in the main urban area,the average concentration of PM10Was higher in the north than in the South.The concentrations of PM10and PM2.5are related to precipitation,relative humi-dity,wind speed and wind direction.
