摘　　要：用JWL-IIB新型固体撞击式空气微生物采样仪对广州市18个监测点的空气微生物含量及其月和季节变化势态进行了观察和研究。结果表明:广州市区室外空气微生物年平均含量为2,298 cfu／m3,室内空气微生物年平均含量为1,792 cfu／m3。各功能区的室外空气微生物平均含量(cfu／m3)大小顺序为:垃圾压缩站(4,573)>商业步行街(3,835)>交通枢纽(1,580)>居民住宅小区(1,413)>工业厂区(1,197)>中心公园(1,187);室内空气微生物含量(cfu／m3)大小顺序为:交通枢纽(2,511)>旅游三星酒店(1,699)>地铁站(1,167)。一年中,市区各监测点室外空气微生物月平均含量变化范围在1,073—4,096 cfu／m3,其中3月份的空气微生物平均含量最高,可达4,096 cfu／m3,而10月份的空气微生物平均含量最低仅为1,073 cfu／m3。四季中,各监测点室外空气细菌和真菌平均含量(cfu／m3)变化均表现为春季(3,716)>夏季(2,300)>冬季(1,816)>秋季(1,553)。可为广州市区公共场所的卫生防疫和环境治理提供科学依据。One year survey on the concentrations and monthly or seasonal variations of airborne microbe in Guangzhou city were analysed and studied with JWL-IIB airborne microbial sampler. The results showed that the ,yearly average airborne microbe content of outdoor was 2, 298 cfu/m^3, and that of indoor was 1,792 cfu/m^3 in Guangzhou city. The monthly variation range of outdoor airborne microbe was from 1,073 to 4, 096 cfu/m^3 , the highest content was 4, 096 cfu/m^3 in March, and the lowest content was 1,073 cfu/m^3 in October. The outdoor airborne bacteria and fungi counts were the highest in spring, next in summer, lower in winter and the lowest in autumn in the four seasons. The yearly average concentrations of outdoor airborne microbe at the Garbage compression station, the business walk street, the key traffic route, the residential area, the industrial district and the garden were 4, 573, 3, 835, 1,580. 1,413, 1,197 and 1,187 cfu/m^3 respectively; and Ones of indoor at the key traffic route, the tourist three star-route hotel and the subway station were 2, 511, 1,699and 1,167 cfu/m^3 respectively. The study on airborne microbe can be used for the research of health prevention and environment control measures in Guangzhou.
