摘　　要：根据2000年6月至2001年5月兰州市大气气溶胶的监测资料,分析了兰州市大气气溶胶的浓度、尺度谱分布及其年、月、日变化规律,进而探讨了大气气溶胶对人体舒适度的影响,分析了大气气溶胶浓度与呼吸道疾病发病人数之间的关系。结果表明:PM10月均浓度与同期呼吸道疾病月发病人数的变化趋势基本一致,两者呈显著性正相关;当PM10日均浓度明显升高后1～2 d,呼吸道疾病发病人数也随之增多。According to the observational data of aerosols over Lanzhou city from June 2000 to May 2001, the concentration and size distribution of aerosols in the atmosphere including their yearly, monthly and daily variation were analyzed, and the influence of atmosphere aerosols on human heath was discussed also. The results show that the variation tendencies of monthly mean density of PM10 and monthly mean number of persons infected with respiratory disease at the same period are basically coincident, they present significant positive correlation. When aerosol concentration is on the high side , the number of persons infected respiratory disease will increase in 1~2 days.
