徐州市空气微生物污染相关性研究

空气微生物是城市生态系统重要的生物组成部分,空气中广泛分布的细茵、真茵孢子、放线茵和病毒等生物粒子不仅具有极其重要的生态功能,还与城市空气污染,城市环境质量和人体健康密切相关.从生态系统角度出发,着重论述了城市微生物气溶胶的粒谱范围、空气微生物浓度的时空变化和空气微生物群落结构的影响因素.

The Correlativity Research of the Xu Zhou City Airborne Microbes Contaminates

Airborne microbes are important biological components in urban ecosystem,they have a direct relation with ecological balance and many life phenomena in nature, and play much important roles in natural cycle of matter. The biological particles, such as bacteria, fungus spores , anfinomyces, virus and so on, are widely distributed in the air. Soil, water, animal feeding, fermentation course and rural activity are the important sources of airborne microbes. They have not only important ecological functions, but also have close relation with urban air pollution, environment quality and human health. Understanding the community structure and dynamic fluctuation of airborne microbes in the urban ecosystem will be helpful in urban planning and management. This paper is a literature summary and study on progresses of airborne microbe in the urban ecosystem. The particle range of microbiological aerosol, the space - time fluctuation of airborne microbe concentration and the influence factors of its community structure in the urban ecosystem were discussed.
