主要研究方向:海洋生物地球化學
主要研究內容
主要從事營養鹽動力學的相關研究。對磷限制對浮游植物氮吸收速率的調節的研究結果表明磷限制主要抑制浮游植物對硝酸鹽的吸收利用;對珠江口不同形態磷的觀測調查,從徑流量季節變化的角度闡釋磷限制出現的原因。圍繞中小尺度過程對營養鹽循環的影響展開的工作表明,冷渦內湍流輸送營養鹽支撐新生產力對初級生產的貢獻明顯低于暖渦。對養殖海灣營養鹽循環的研究,揭示了綜合養殖海灣不同養殖生物種類間在釋放、吸收、移除營養鹽的相互協同作用;闡明了養殖活動對河口、潟湖營養鹽的循環過程及沉積環境的影響機制,為養殖模式單一的海灣的生態環境可持續發展提供科學依據。基于以往在人類活動對海洋生態環境影響的相關工作,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。發表論文30余篇。
