真菌孢子在室内和室外空气中都普遍存在，本文调查了敦煌莫高窟空气中真菌孢子的时空分布、组成及其影响因素。2008年9月至2009年8月，利用FA-1型安德森六级采样器，对莫高窟开放式、半开放式、封闭式3种类型的洞窟及室外区域的可培养真菌进行了每月一次的采样。所有研究点的总可培养真菌数均值为187.45 ± 37.76 CFU/m3，其中OC、SC、CC、OD分别为110.52 ± 17.40 CFU/m3、137.81 ± 26.67 CFU/m3、245.39 ± 37.20 CFU/m3、240.87 ± 54.91 CFU/m3。最普遍的真菌是枝孢属，非孢子真菌，青霉属，链格孢和曲霉属（Aspergillus spp.）在所有四个采样点。空气中真菌的数量和多样性一般较高的CC和OD比OC和SC。大多数真菌属有明显的季节变化，在夏季和秋季观察到较高的水平。Pearson相关分析表明，环境真菌水平与温度和游客人数呈正相关，与相对湿度和降雨量呈负相关。结果表明，游客对莫高窟环境真菌的浓度和组成有明显的影响，为莫高窟的保护和管理提供了参考。
Fungal spores are ubiquitous and can be found in both outdoor and indoor air samples, we investigated the temporal and spatial distributions, compositions, and determinants of ambient airborne fungi in Mogao Grottoes of Dunhuang, China. Culturable fungi in three categories of caves, Open Cave (OC) to visitors, Semi-open Cave (SC), and Closed Cave (CC) and an outdoor area (OD) in Mogao Grottoes monthly from September 2008 to August 2009, using a six-stage Anderson FA-1 sampler. The grand mean of total culturable fungi was 187.45 ± 37.76 colony-forming units (CFU)/m3for all sites considered, and the number was 110.52 ± 17.40 CFU/m3, 137.81 ± 26.67 CFU/m3, 245.39 ± 37.20 CFU/m3, 240.87 ± 54.91 CFU/m3in OC, SC, CC, OD. The most prevalent fungi were Cladosporium spp., non-sporing fungi, Penicillium spp., Alternaria spp. and Aspergillus spp. at all four sampling sites. Airborne fungal numbers and their diversity were generally higher in CC and OD than in OC and SC. Most fungal genus had significant seasonal variations, higher levels were observed in summer and autumn. Pearson correlation analysis showed that the levels of ambient fungi were correlated positively with temperature and visitor numbers, but negatively with relative humidity and rainfall. The results suggested that the visitors have an obvious influence on concentrations and compositions of ambient fungi in Mogao Grottoes providing information to be considered in conservation and management.
