摘　　要：目的了解大学生宿舍空气微生物污染状况,探讨影响大学生宿舍空气细菌总数的因素,为制订提高学生宿舍空气卫生质量的措施提供依据。方法采用自然沉降法对西藏大学新校区96间宿舍进行空气细菌总数监测。结果西藏大学学生宿舍空气中细菌总数总超标率为17.71%;下午大学生宿舍空气细菌总数944(553~1 573)cfu/m^3多于上午472(157~1 376)cfu/m^3;男生宿舍空气细菌总数超标率(27.08%)高于女生宿舍(8.33%);感官卫生状况良好的宿舍空气细菌总数超标率(3.45%)低于感官卫生状况较差者(38.89%),随感官卫生状况的改善空气细菌总数超标率降低(rs=0.314,P=0.002);摆放有绿色盆景的宿舍空气细菌总数超标率(6.25%)低于无绿色盆景的宿舍(23.44%);宿舍内存在异味时,宿舍空气微生物污染加重;不同楼层,大学生宿舍空气细菌总数超标率随楼层升高而降低(rs=-0.329,P=0.001)。结论大学生宿舍空气细菌总数超标率与居住者性别、楼层、时间、感官卫生状况、宿舍内是否有异味及是否摆放有绿色盆景有关,需采取综合防治措施,降低大学生宿舍空气中细菌总数。Objectives To know the condition polluted by air microbes in the dorms of college students,and to find the factors that influencing gross bacteria in the air of college students＇ dorms,in order to provide the basis for promoting the air quality of students＇ dorms.Methods Natural sedimentation was adopted to monitor grass air bacteria in 96 dorms at the new campus of Tibet University.Results The gross air bacteria over-standard rate was 17.71% in the dorms of college students at Tibet University.The gross air bacteria of the afternoon was 944（ 553-1 573） cfu / m3,which was more than that of the morning 472（ 157-1 376） cfu / m3.The gross air bacteria over-standard rate of boys＇ dorms was 27.08%,which was higher than that of girls＇ dorms（ 8.33%）.The gross air bacteria over-standard rate in good condition of sense health was3.45% better than that in worse condition of sense health（ 38.89%）.With the improvement of the sense health,the gross air bacteria over-standard rate was reduced（ rs= 0.314,P = 0.002）.The gross air bacteria over-standard rate in dorms that have green plants was 6.25% better than the dorms without green plants（ 23.44%）.There was more pollution by air microbes when there was a peculiar smell in the dorms.On the different floors,the gross air bacteria over-standard rate in dorms of college students can be decreased with storey.The higher you live in,the lower the gross air bacteria over-standard rate in dorms of college students was（ rs=- 0.329,P = 0.001）.Conclusions The gross air bacteria over-standard rate of college students relate to sex,storey,time,condition of sense health,whether existing peculiar smell and putting green plants.We should adopt comprehensive control measures to reduce the gross air bacteria in the dorms of college students.
