中文摘要：
物理和生物扰动对营养物在沉积物-水界面行为及释放效应的研究近年来已被人们广泛关注。本项目以太湖为重点研究对象，应用自行研发的水动力定量控制装置和微界面信息获取技术，对极端风情(台风)强度下的水动力作用、不同种类（河蚬、摇蚊幼虫和水丝蚓）和数量的底栖生物扰动过程进行模拟，分析不同时空尺度界面的物理、化学和生物学特性变化，弄清了水动力和底栖生物扰动对浅水湖沉积物的物理和生物影响尺度的定量化问题；着重揭示湖泊沉积物和间隙水中营养物对界面扰动和迁移的物化响应、界面微生物和酶活性变化及其对磷再生转化的影响。首次发现底栖生物对表层沉积物改造作用降低了沉积物再悬浮的起动风速，底栖动物通过掘穴、钻孔等作用对水底边界层磷的扩散系数随生物种类的不同而呈指数或线性关系；发现动力再悬浮过程并不总是引起沉积物释放，大风浪扰动使一些湖区沉积物磷更易趋向形成稳定性形态，颠覆了人们关于扰动一定会产生界面磷释放的传统认识。项目估算的底栖生物和风浪扰动下的全湖释放量，为太湖内源治理提供了重要科学依据。项目SCI收录论文31篇，总影响因子61.2；出版专著2部，获奖1项，相关成果在太湖地区湖泊疏浚中得到广泛应用。
