摘　　要：重量法测定了2006年11月15—25日焦作市区PM10(可吸入颗粒物)的质量浓度,同时对相应的气象条件进行了连续监测,并利用监测结果深入分析了焦作市区PM10的污染状况、主要污染物PM10与风速、湿度及温度等相关气象条件的变化规律.结果表明:PM10的质量浓度在冬季的变化主要受风速的影响;PM10的质量浓度与湿度成正比,与风速成反比关系,与温度的相关性不大;焦作市PM10质量浓度超标严重.Mass concentrations of PM10 （inhalation particle matter） were measured by gravimetric method during Nov. 15th -25th 2006 in Jiaozuo city, and the meteorological conditions were also measured. By using monitoring results of PM10 the relation of main pollution status of PM10 and meteorological conditions, such as wind speeds, humidity and temperature was analyzed. The results showed that the mass concentrations variation of PM10 and wind speeds had a high degree of correlation, the humidity was in direct ratio to the mass concentrations of PM10, the wind speeds were in inverse ratio to it, and temperature had little relationship of it ; The mass concentrations of PM10 in the downtown area of Jiaozuo was found to exceed, with a great extent of the National Air Quality Standard.
