摘　　要：利用邯郸市区4个代表站2006年逐时可吸入颗粒物PM10浓度监测资料和邯郸市观测站地面气象要素的逐时观测资料,分析了邯郸市主要空气污染物——PM10的时空分布特征,结果表明:PM10平均浓度采暖期明显大于非采暖期;日变化规律为上午浓度最高,夜间次之,下午浓度最低,采暖期为双峰双谷型,非采暖期为一峰一谷型;弱风、低温和潮湿的气象条件有利于可吸入颗粒物的积累,增加PM10浓度。Utilizing the hourly monitoring data of inhalation particle matter （PM10） in 2006 at four stations and hourly ground meteorological data at observation station in Handan, the temporal and spatial variation features of PM10 in Handan were studied. The results showed PM10 concentration in heating peri- od is considerably higher than in non - heating period. The daily variation of PM10 pollution is the highest at a.m. and the lowest at p. m. ; PM10 concentration in heating period is double peck - valley and sole peck - valley in non - heating period. The weather conditions of weak wind, low temperature and moist are propitious to the accumulation of inhalation particle matter and increasing concentration of PM10.
