摘　　要：采集大连市4个大气自动监测点位30 d PM2.5和PM10质量浓度小时值的监测数据,通过对每个点位720个有效数据对的统计分析,研究二者质量浓度的相关性及PM2.5/PM10比值的分布情况,并研究了气象因素对PM2.5与PM10的影响。结果表明,雾使PM2.5与PM10浓度都减小,但二者比值也随之降低;强风会使PM10浓度增大,但PM2.5浓度却减小。Hour values of PM5.5 and PM10 mass concentration were acquired from four air monitoring sites in Dalian. Study on the correlativity between PM2.5 and PM10, the distribution of PMzs/PMlo ratio were carried out based on the statistic analysis of 720 valid data of each site. The influence of some meteorological factors on PM2.5 and PM10 was also studied. On foggy day, the mass concentration of both PM2.5 and PM10 decreased, but PM2.5/PM10 ratio also decreased. Strong wind made the concentration of PM10 increase, while the concentration of PM2.5 decreases on the contrary.
