摘　　要：微纳米气泡由于其独特的物理化学特性,如超高稳定性、易于产生自由基和高的传质效率等,引起国内外学者的广泛关注。近年来,微纳米气泡技术作为一种新兴的高效技术手段,被广泛应用于水产养殖、农业种植、浮选、水处理等方面,而在改善土壤方面的应用相对较少。基于微纳米气泡改善土壤已有研究成果,对微纳米气泡的基本性质,国内外研究进展及应用进行了综述与探讨,初步明晰了微纳米气泡在土壤改善过程中的作用效果,包括可以增强土壤通透性,有效去除水体中的有机和金属污染物质,改变微生物团簇结构,降低矿物沉积能力等,以期为后续微纳米气泡改善土壤环境的研究带来一定的启发。Due to their unique physical and chemical characteristics such as ultra-high stability,easily producing free radicals and high mass transfer efficiency,micro-nanobubbles continue to arouse the exploration interest of domestic and foreign researchers.In recent years,micro-nanobubble technology as a new and high-efficiency technique,has been widely used in aquaculture,agricultural planting,flotation,water treatment,etc.But it is insufficient in the application of improving the soil environment.In this review,based on the existing research results of improving soil environment with micro-nano bubbles,their basic properties,domestic and overseas research progress and applications were reviewed and discussed,and the effect of micro-nanobubbles in the soil improvement process was preliminarily clarified,which could enhance soil permeability,effectively remove organic and metal pollutants in water,change the structure of microbial clusters,and reduce the ability of mineral deposition.It was expected to bring some inspiration for subsequent research on micro-nanobubbles to improve the soil environment.
