目的：探讨坑道在官兵密闭生存训练期间生活区的微生物分布。方法定时、定点对生活区进行安德森采样，布点主要位于人员居住的两条通道（A、B两区）及厕所（C区）；采样后进行各种微生物的培养和鉴定。结果①整条坑道生活区细菌总数为125～37800个／m3，A、B、C三区细菌菌落总数平均为2692、1844、2199个／m3，整条坑道生活区细菌总数平均为2245个／m3；坑道生活区内真菌整体分布为0～10017个／m3，A、B、C三区真菌数平均为1064、883、1011个／m3，整条坑道生活区真菌数平均为986个／m3。②生活区布点测试细菌菌落数呈现三大特点：A、B两区细菌总数整体呈现“三峰”、C区呈现“双峰”现象；A、B生活区由初期的低菌落数以大幅升降态势波动；C区由初期的高菌落数以相对稳定的态势逐渐降至最低。真菌数量的变化规律有其自身的特点，整体变化趋势呈现波浪式无规律走向。③密闭生存训练期间坑道生活区空气中分布的微生物有：球菌（微球菌属、科氏葡萄球菌、表皮葡萄球菌、马葡萄球菌）、杆菌（鲍氏不动杆菌、鲁氏不动杆菌、粪产碱菌）、真菌（毛霉属、酵母属）。结论密闭生存训练期间坑道空气中微生物含量未超出军用卫生标准，但比同类型坑道高；微生物分布的“多峰”现象反映了屯兵期间坑道空气微生物变化有其自身规律和特点；生活区空气微生物种类多是条件致病菌，但若忽视仍会引起官兵发病。

Objective To investigate the distribution of air microorganisms in soldies′living quarters of one under-ground tunnel during airtight survival training .Methods Anderson sampling was carried out in Area A and Area B ( living quarters) and Area C (a toilet) at designated time and place.After sampling, the culture and identification of microorgan-isms were finished .Results ①In the living quarters of the whole underground tunnel , the total number of bacteria ranged from 125 to 37 800/m3,but it was 2692, 1844 and 2199/m3, respectively in Area A, B and C.The mean number of bac-teria was 2245/m3 .The number of fungi ranged from 0 to 10 017/m3 .The total number of fungi of Area A , B and C was 1064 , 883 and 1011/m3 .The mean number was 986/m3 .②The number of bacteria in the living areas presented three fea-tures:the total bacteria showed overall "three peaks"in Area A and B, but"twin peaks"in Area C.In Area A and B, the number of bacteria exhibited low colony at first but fluctuated heavily later .In Area C, it decreased gradually to the mini-mum,and the fungi showed a wavy and irregular trend .③The air microbial species included cocci ( Micrococcus, Coriolis of Staphylococcus aureus, S.epidermidis and S.equorum) , bacilli ( Acinetobacter baumannii, A.lwoffii and Alcaligenes faeca-lis),and fungi (Mucor and Saccharomyces).Conclusion Although the content of microorganisms was up to the military hygiene standards , it was higher than in the same kind of tunnels .The"multi peak"phenomenon of microbial distribution suggests that the change of air microorganisms in tunnels has its own characteristics .Most of the air microorganisms are con-ditioned pathogens that may cause illness if they are not under control .
