摘要
调查了南京市主要功能区大气微生物中常见种类的细菌和霉菌类,研究了细菌和霉菌类的生态分级和变化规律,比较了大气微生物与大气监测指标PM10、SO2、NO2的相关性。通过分析2000年10月至2001年8月6个功能区4个季节的监测结果,得出山西路监测点微生物数量最高,并且该点微生物中是以细菌为优势种,其次是霉菌属的马丁霉菌和耐渗透压霉菌。通过生理生化试验鉴定细菌和霉菌类,得出南京市大气微生物中细菌基本以微球菌属为主,霉菌以青霉属、曲霉属为主。大气微生物数量统计结果表明,南京市主要功能区微生物总量(均值)从高到低的顺序为:山西路(商业区)>中华门(交通区)>瑞金路(居住区)>迈皋桥(工业区)>玄武湖(对照点)>草场门(文教区)。大气化学监测指标PM10、SO2、NO2分析结果也表明大气微生物的数量变化与之呈一定的正相关关系,尤其与PM10关系更为密切。
The most common microbe in atmosphere in Nanjing, bacteria and mold, were investigated. The dynamic change of bacteria and mold was researched. The relationship of atmosphere microbe and other indicators, such as PM10, SO2 and NO2, was compared. Monitoring data in six function area with the time from Oct 2000 to Aug 2001 was analyzed, result indicated that the amount of microbe in Shaxilu monitoring site was the highest, bacteria was the dominant species. Test was done to identify bacteria and mold, bacteria was mostly Micrococcus, mold was mostly Penicillium and Aspergillus. Amount statistics indicated that the microbe amount was Shaxilu>Zhonghuamen>Ruijinlu>Maigaoqiao>Xuanwuhu>Caochangmen. The analysis about PM10, SO2, NO2 indicated the amount change of microbe was relative with them, especially PM10.
