摘　　要：土壤微生物对大气对流层臭氧浓度升高的响应是全面评价臭氧浓度变化对陆地生态系统影响的关键。本文简要回顾了大气臭氧浓度升高对生态系统的影响概况,介绍了土壤微生物对人工控制微域环境臭氧浓度增高的响应研究进展,并提出了农田生态系统土壤微生物生物量与活性(包括硝化反硝化作用)、群落结构与功能(包括秸秆降解过程)、有益微生物(如菌根真菌)及其调控技术是今后大气臭氧污染研究领域的重要方向。Elevated tropospheric O3 concentration has altered the whole biosphere and eco-environment worsely, and has influenced indirectly on soil microbes. Investigating soil microbial responses was the key to evaluate terrestrial ecosystems＇ change under elevated tropospheric O3 concentration. This article reviewed the general situation of elevated tropospheric O3 concentration effects on terrestrial ecosystems, and introduced the responses of soil microbes under artificial environment condition with designed O3 concentrations. Then, more experiments were suggested to investigate the effects of elevated tropospheric O3 concentration on soil microbes, including soil microbial biomass and activity （such as nitrification and denitrification）, microbial community structure and function （such as straw decomposition）, as well as beneficial microbes （such as arbuscular mycorrhizal fungi） and their application in controlling ozone disaster.
