微生物在溶解有机物（DOM）的生物地球化学过程中发挥着至关重要的作用，DOM的性质也显着影响微生物群落特征的变化。这种相互依存的关系对于水生生态系统内物质和能量的流动至关重要。沉水植物的存在、生长状态和群落特征决定了湖泊对富营养化的敏感性，恢复健康的沉水植物群落是解决这一问题的有效途径。然而，从以浮游藻类为主的富营养性湖泊向以沉水植物为主的中低营养性湖泊的转变涉及重大变化。水生植被的变化极大地影响了DOM的来源、组成和生物利用度。沉水植物的吸附和固定功能决定了DOM等物质从水体向沉积物的迁移和储存。沉水植物通过控制湖中碳源和养分的分布来调节微生物群落的特征和分布。它们通过其独特的附生微生物进一步影响湖泊环境中微生物群落的特征。沉水植物衰退或恢复的独特过程可以通过其对 DOM 和微生物群落的双重影响，改变湖泊中 DOM-微生物的相互作用模式，最终改变湖泊中碳和矿化途径的稳定性，例如甲烷和其他温室气体的释放。这篇综述为 DOM 的动态变化以及微生物组在未来湖泊生态系统中的作用提供了新的视角。

Response of dissolved organic matter (DOM) and microbial community to submerged macrophytes restoration in lakes: A review

Microorganisms play a crucial role in the biogeochemical processes of Dissolved Organic Matter (DOM), and the properties of DOM also significantly influence changes in microbial community characteristics. This interdependent relationship is vital for the flow of matter and energy within aquatic ecosystems. The presence, growth state, and community characteristics of submerged macrophytes determine the susceptibility of lakes to eutrophication, and restoring a healthy submerged macrophyte community is an effective way to address this issue. However, the transition from eutrophic lakes dominated by planktic algae to medium or low trophic lakes dominated by submerged macrophytes involves significant changes. Changes in aquatic vegetation have greatly affected the source, composition, and bioavailability of DOM. The adsorption and fixation functions of submerged macrophytes determine the migration and storage of DOM and other substances from water to sediment. Submerged macrophytes regulate the characteristics and distribution of microbial communities by controlling the distribution of carbon sources and nutrients in the lake. They further affect the characteristics of the microbial community in the lake environment through their unique epiphytic microorganisms. The unique process of submerged macrophyte recession or restoration can alter the DOM-microbial interaction pattern in lakes through its dual effects on DOM and microbial commu-----nities, ultimately changing the stability of carbon and mineralization pathways in lakes, such as the release of methane and other greenhouse gases. This review provides a fresh perspective on the dynamic changes of DOM and the role of the microbiome in the future of lake ecosystems.
