目的 探讨空气中芽枝菌属孢子飘散数量、规律及其与气象因素的关系。方法 对 2000年 3月～2001年 2月同时应用曝片、曝皿法,进行为期一年的调查。并将芽枝菌属曝片监测计数资料与同期江西省气象台气象因素资料进行了多元逐步线性回归分析。结果 全年观察到芽枝菌属孢子5033个,菌洛5129个,芽枝菌属孢子飘散量与平均湿度（r3=0.17,P<0.05）、最大风速（r5=0.219,P<0.05）、平均气压（r1=0.246,P<0.05）和平均气温（r2=0.269,P<0.05）呈负相关。结论 南昌城区空气中芽枝菌属飘散高峰位于5月,这与气象因素有关。
Objective To investigate the quantity and regularity of airborne spores of Mycobacterium sp. And their relationship with meteorological factors. Methods From March 2000 to February 2001, a simultaneous one-year investigation was conducted by applying the exposure method and the exposure method. The multiple linear stepwise regression analysis of the meteorological data of the meningitidis and the meteorological factors of the meteorological station in Jiangxi Province during the same period was carried out. Results The results showed that 5033 spores of Mycobacterium sp., 5129 spores of Mycobacterium sp., Mean spore release and average humidity (r3 = 0.17, P <0.05) and maximum wind speed (r5 = 0.219, Mean pressure (r1 = 0.246, P <0.05) and mean temperature (r2 = 0.269, P <0.05) were negatively correlated. Conclusion Nanchang airborne Mycetoma in the air floating peak in May, which is related to meteorological factors.
