Role of Periphyton in Migration and Transformation of Carbon,Nitrogen,and Phosphorus Elements at Soil-Water Interface
摘要
Abstract
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 mi-croorganisms can interact with each other to form more complex microbial aggregates,which are eco-logical 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 literature 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 literature was conducted using VOSviewer soft-ware.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 com-bined with isotopic analysis.The objective of out study aimed to strengthen the understanding of bio-geochemical 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.关键词
