摘　　要：针对空气细菌真菌污染评价存在的不足,搜集整理现有研究文献中对室内外空气细菌和真菌的现场实测数据,利用拟合优度χ^2检验法证明了在显著性水平α为0.05时,室内外空气细菌和真菌分别采用撞击法和沉降法的8组浓度数据均服从正态分布,并结合正态分布的3σ原则和现行评价标准,给出了可用于空气细菌真菌分级评价的浓度建议区间,研究成果可为将来制定空气细菌真菌污染的评价标准提供参考.In this paper,in order to settle existing problems in the assessment of air bacteria and fungi contamination,the indoor and outdoor air bacteria and fungi filed concentrations by impact method and settlement method in existing documents were collected and analyzed,then the goodness of chi square was used to test whether these concentration data obeyed normal distribution at the significant level of α = 0. 05,and combined with the 3σ principle of normal distribution and the current assessment standards,the suggested concentrations ranges of air microbial concentrations were determined. The research results could provide a reference for developing air bacteria and fungi contamination assessment standards in the future.
