摘　　要：裸土风蚀扬尘是城市空气颗粒物污染的重要来源,防治裸土风蚀扬尘是当前研究的热点。利用自然界广泛存在的微生物实现固结裸土从而抑制其风蚀扬尘的目的,是一种好方法。在微生物固结土体介绍的基础上,综述了微生物固结裸土抗风蚀扬尘的机理,分析了微生物固结裸土抗风蚀扬尘的影响因素,最后对微生物固结裸土抗风蚀扬尘的主要研究方向进行了展望。Wind erosion dust of bare soil is a main source of urban air particulate pollution,so preventing wind erosion dust of bare soil becomes the hotspot of current research.Using the microorganisms existing in the nature to consolidate bare soil is a new way to resist wind erosion dust.After introduction of microbial consolidation of soil,the mechanism of microbial consolidation of bare soil and its resistance of wind erosion dust were summarized,and the influence factors were analyzed.Finally,the main research directions of microbial consolidation of bare soil and its resistance of wind erosion dust were prospected.
