为了探明本地区空气中飘浮真菌种类、数量以及季节消长规律，从而指导临床对真菌过敏病人的诊断和治疗。本调查采用曝皿法和曝片法对气传真菌进行了全年调查。曝皿法得到真菌菌落２３０９个，２９个种属，主要真菌有青霉菌和交链菌等，４～１０月是真菌菌落的高峰期。曝片法得到各类孢子７０８７个，３３个种属，主要真菌孢子为交链孢菌、附球孢菌，４～１１月为真菌孢子飘散高峰。调查表明：长春地区大气中普遍存在真菌，种类繁多，足以成为某些过敏病人的重要致敏因素，此项研究对于临床诊断、治疗具有重要意义。
In order to ascertain the species, quantity and seasonal variation of floating fungi in the air in the region, the clinical diagnosis and treatment of fungal allergy patients are guided. The survey conducted a full-year survey of airborne fungi using the plate-in method and exposure method. There were 2309 fungal colonies and 29 species of fungi in the plate-dish method. The main fungi were Penicillium and Alternaria, and the peak of fungal colonies occurred from April to October. There were 7087 species and 33 species of spores in the exposure method. The main fungal spores were Helminthosporium and coccidioides, and the peak of fungal spore released from April to November. The survey shows that there are many kinds of fungi in the atmosphere of Changchun, which are enough to become important sensitizing factors for some allergic patients. This study is of great significance for clinical diagnosis and treatment.
