摘　　要：为了解悬浮微生物在通风管道中的分布特性,先后于2003年夏、冬季对长沙市某一综合性大楼展开了实测调查.采用了空气微生物检测仪(JWL-IIB200)对通风空调系统管道内悬浮微生物进行采样,并在实验室进行培养分析;采用了尘埃粒子计数器(MetOneA2400)等仪器对可能影响悬浮微生物的因素进行测试和分析.实测结果表明,通风空调管道中悬浮微生物的污染分布同管道的位置以及管道中的温度、湿度、风速等环境参数紧密相关.将管道内悬浮微生物的污染物分布特点与相同测点的总悬浮颗粒物浓度、颗粒物的沉积量、环境温湿度等参数相对比,均反映出一定的相关性.To understand the distributing characteristics of suspended microbes in ventilation ducts, a commercial building in Changsha, China was investigated in the summer and the winter of 2003. Microbial species, distribution and influencing factors in the ducts were detected by suspended microbial monitors（JWL-II]3200, Particle Counter（MetOne A2400）, etc. The results revealed some characteristics of the microbial species and their distribution in HVAC systems. Several charts were utilized to analyze the characteristics, and then the factors influencing microbial distribution were further discussed for better prevention of microbial pollutants.
