中文摘要:
      生长在淹水固体表面和土水界面之间的周丛生物由微藻、真菌、细菌等微生物群落和胞外聚合物等物质组成,它们能够相互作用形成更复杂的微生物聚集体,具有生态稳定性,直接影响土-水界面之间的物质循环、能量流动和信息交换。以“periphyton”“periphytic biofilm”“周丛生物”和“周丛藻类”等作为主题检索词,在Web of Science(WOS)数据库和中国知网平台(CNKI)检索2019-2023年相关文献,并通过VOSviewer软件进行共现分析。结果表明,目前关于周丛生物的研究主要集中在其对河流、湖泊、稻田等浅水生态系统中氮磷迁移转化的影响及其调控机制等方面,但对碳循环的影响研究相对较少。在此重点总结了周丛生物对碳氮磷生源要素迁移转化的作用及其机制,并在此基础上提出结合同位素分析等手段研究周丛生物对碳固定和矿化等方面的研究展望。
英文摘要:
      Periphyton, growing on the surface of submerged solids and at the soil-water interface, consists of microorganisms such as microalgae, fungi, bacteria, and extracellular polymers. These microorganisms can interact with each other to form more complex microbial aggregates, which are ecological stable and directly affect the material cycle, energy flow, and information exchange between the soil and water interface. In this study, "periphyton", "periphytic biofilm", "periphyton algae" were selected as search terms, and the relevant literatures for the period from 2019 to 2023 were searched in the Web of Science (WOS) database and the China Knowledge Network (CNKI) platform. Then, the keyword co-occurrence analysis of the retrieved literatures was conducted using VOSviewer software. Results show that current research on periphyton primarily focused on the effect of periphyton on the migration and transformation of nitrogen and phosphorus in shallow water ecosystems such as rivers, lakes, paddy fields, as well as the regulatory mechanisms. There were relatively few studies on the effect of periphyton on the carbon cycle. Based on existing literature, we further summarized the impact and mechanism of periphyon on the migration and transformation of carbon, nitrogen, and phosphorus. Additionally, we proposed the future research directions of periphytic organisms, such as the research perspective of carbon fixation and carbon mineralization affected by periphyton combined with isotopic analysis. The objective of out study aimed to further strengthen the understanding of biogeochemical cycling processes in ecosystems and provide theoretical support for precise prevention and control of non-point source pollution through regulating the growth processes of periphyton.
