高被引论文

近期，团队收到美国湖沼与海洋学会ASLO旗下Limnology and Oceanography期刊邮件，研究成果Eutrophication and temperature drive large variability in carbon dioxide from China's Lake Taihu（第一作者：肖启涛博士，通讯作者：段洪涛研究员）入选该期刊2022年1月至2023年12月发表论文引用次数最高的10篇论文之一。 

湖泊作为具有独特生态功能的地理单元，在全球CO₂收支估算中具有重要作用。过去数十年在全球变化的背景下，湖泊环境发生快速变化，主要包括富营养化加剧和水温升高等，但是，湖泊CO₂收支及其源汇过程对全球变化的响应还存在认知空白，今后湖泊CO₂将如何变化还很不明确。为解决上述科学问题, 团队成员肖启涛博士选取太湖为典型代表湖泊，以太湖湖泊生态系统研究站长期观测数据为基础，深入剖析了富营养化湖泊CO₂变化的环境驱动机制及其对全球变化的响应，并发现在未来气候变暖以及湖泊生态修复等措施实施的双重影响下，湖泊CO₂排放可能出现显著降低趋势，甚至转变成CO₂吸收汇。

Limnology and Oceanography 创刊于1956年，是美国海洋与湖沼学会主办的海洋与湖沼学领域颇具影响力的学术期刊，文章评判标准是其对湖沼学和海洋学领域发展要做出有原创性和有显著价值的贡献。目前，团队已连续在Limnology and Oceanography期刊发表论文2篇。近年来，团队聚焦湖泊等内陆水体碳循环主题，已经在水体碳来源解析、机理揭示、收支估算等方面做出系列创新成果，在Science Bulletin、Limnology and Oceanography、Environmental Science and Technology、Water Research、Remote Sensing of Environment等国际著名刊物发表高质量SCI论文20余篇，标志着团队在湖泊碳循环学方面研究工作已经得到国内外同行广泛认可。研究成果解决了高生产力湖泊排碳“悖论”问题，揭示了水体温室气体产汇关键过程，支撑了水域系统碳源汇精细评估，部分成果正在积极“落地”，服务于水域生态系统碳汇提升和高效利用。
