目的：校园空气真菌对校园环境以及师生健康具有重要影响,对校园空气真菌的分布特征进行研究具有重要意义。方法于2014年8月—2015年3月采用自然沉降法,对校园内9个不同地点进行空气真菌取样,并根据中国科学院生态中心推荐使用的空气微生物评价标准进行污染评价。结果(1)校园空气真菌总体评价为较清洁水平( II级),全年清洁率(清洁及较清洁)为77．8%。(2)校园空气真菌浓度变化范围为122~1966 CFU/m3,平均浓度为560 CFU/m3,其中室内空气真菌平均浓度为392 CFU/m3,室外为1147 CFU/m3,室内与室外空气真菌浓度差异极显著(P<0．01∗∗)。(3)校园不同季节空气真菌浓度情况为夏季(789 CFU/m3)>秋季(551 CFU/m3)>冬季(541 CFU/m3)>春季(359 CFU/m3),各季节之间均无显著差异(P>0．05∗)。结论研究区空气真菌浓度评价为较清洁水平。%The airborne fungi in a university campus demonstrated significant effects on the environment and the health of teachers and students. Currently, airborne fungi were sampled by natural sedimentation at nine sites of campus from August 2014 to March 2015 , and the air pollution by fungi was evaluated according to the standards of air microorganism recommended by Research Center for Eco-environmental Sciences, Chi-nese Academy of Sciences. The results showed that the overall evaluation of airborne fungi in campus was considerably clean ( II level) , and the clean ratio ( clean and less clean) accounted for 77. 8%. The fungal concentration in the air of campus ranged from 122 CFU/m3 to 1 966 CFU/m3 , with an average of 560 CFU/m3 , the mean concentration of airborne fungi were 392 CFU/m3 in the indoor and 1 147 CFU/m3 in the out-door , and their difference was significant ( P<0 . 01∗∗) . The concentrations of airborne fungi in the campus were 789 CFU/m3 in summer, 551 CFU/m3 in autumn, 541 CFU/m3 in winter, and 593 CFU/m3 in spring, although no obvious difference were investigated among different seasons ( P>0 . 05∗) , reflecting the rela-tively clean environment of campus.
