采用沉降平板法调查某大学图书馆藏书室空气中真菌粒子数状况。结果表明：该图书馆室内空气真菌粒子总平均沉降量为１１．６８个／皿．５ｍｉｎ。不同楼层书库的真菌粒子沉降量差异有显著性（Ｐ＜０．０５）；书库高于阅览室；上午１１００及下午５００高于上午８００及下午２００；书库湿度超标率高于阅览室（Ｐ＜０．０１）。藏书室的楼层、类型、湿度、通风状况及不同时间等因素与沉降量有关
Investigation of the number of fungal particles in the air of a university library by using the settlement method. The results showed that the total average indoor air fungal particle settling in the library was 11.68 pcs / dish. 5min. There was significant difference (P <0.05) in the amount of fungal sedimentation among different floor bookstores; the bookstore was higher than the reading room; 1100 and 500 in the morning were higher than 800 and 200 in the morning; 0.01). Library floor, type, humidity, ventilation and different factors such as time and the amount of settlement
