李瑞環(huán)，博士，助理研究員，中共黨員。畢業(yè)于中國海洋大學(xué)。
主要研究方向：海洋生物地球化學(xué)
主要研究內(nèi)容
主要從事營養(yǎng)鹽動力學(xué)的相關(guān)研究。對磷限制對浮游植物氮吸收速率的調(diào)節(jié)的研究結(jié)果表明磷限制主要抑制浮游植物對硝酸鹽的吸收利用；對珠江口不同形態(tài)磷的觀測調(diào)查，從徑流量季節(jié)變化的角度闡釋磷限制出現(xiàn)的原因。圍繞中小尺度過程對營養(yǎng)鹽循環(huán)的影響展開的工作表明，冷渦內(nèi)湍流輸送營養(yǎng)鹽支撐新生產(chǎn)力對初級生產(chǎn)的貢獻明顯低于暖渦。對養(yǎng)殖海灣營養(yǎng)鹽循環(huán)的研究，揭示了綜合養(yǎng)殖海灣不同養(yǎng)殖生物種類間在釋放、吸收、移除營養(yǎng)鹽的相互協(xié)同作用；闡明了養(yǎng)殖活動對河口、潟湖營養(yǎng)鹽的循環(huán)過程及沉積環(huán)境的影響機制，為養(yǎng)殖模式單一的海灣的生態(tài)環(huán)境可持續(xù)發(fā)展提供科學(xué)依據(jù)。基于以往在人類活動對海洋生態(tài)環(huán)境影響的相關(guān)工作，主持國自然青年基金，作為子課題負責人或項目骨干參加國自然面上項目、國自然重點項目、廣東省重點項目等多項。發(fā)表論文30余篇。
