摘　　要：经典海岸动力学理论认为,海岸泥沙的侵蚀特性仅与物理化学因子有关。潮滩上大量微生物及其分泌的黏性物质形成的生物膜,附着泥沙颗粒而展现出的生物稳定效应,是新的研究难点,也是国际前沿和热点问题。目前微生物作用对于潮滩泥沙稳定性影响的研究尚处于发展阶段。结合国内外文献综述了潮滩微生物及其生物膜的分布特征,分析了潮滩微生物对海岸泥沙理化特性及稳定性的贡献及其作用方式,针对研究现状中的不足,对今后的研究方向提出了展望。研究成果可以丰富海岸动力学和泥沙运动力学的知识体系和学科内涵,发展河口海岸生物泥沙研究新方向。According to the conventional theory of coastal dynamics, the erodibility of coastal sediment is merely related to physical and chemical properties. The biofilms on the tidal flat formed by quantities of microorganisms and their secreted viscous substances, which exhibit biological stability effects on the attachment of sediment particles, has become a cutting-edge research topic worldwide. At present, research on the biostabilization of sediments in tidal flats is still in the development stage. In this paper, the distribution of intertidal biofilms and their basic properties are reviewed. How biofilms mediate the physicochemical properties, and the stability of coastal sediments is further analyzed. Relevant research can enrich the research scope of sedimentology and coastal dynamics, which contributes to the development of a novel branch to study the estuarine and coastal bio-sediment interaction.
