摘　　要：通过对近十几年来河口最大浑浊带浮游植物生态动力过程研究的报道进行综述 ,阐明该方面研究的最新进展。研究结果表明 ,河口最大浑浊带的湍流混合过程增大了浮游植物细胞光合作用的机会 ;重力环流致使浮游植物及其光合作用所需的物质能较长时间的停留 ;再悬浮过程使微型底栖藻类对最大浑浊带水体中叶绿素产生明显贡献 ;锋面强烈的辐合聚集作用则可使浮游植物在锋面附近出现高值现象。最后对河口最大浑浊带浮游植物生态动力过程的继续研究提出了几点看法。The physical processes effects on plankton, and the interactions between physical processes and biological processes are the main research field of GLOBEC. Estuary is an important area of human activities, complex dynamical processes and frail ecology. The importance of research on estuary has been gradually recognized since the research plan of LOICZ was put forward by IGBP. Estuarine ecosystem is similar to marine ecosystem in many aspects. However, because the biological condition and transport processes are different, the structure of biological population and spatial variation are also different, a special ecosystem is formed in the estuary. The special horizontal transport caused by the interaction between the dynamics of river and ocean, front, stratification, turbulence mixing are the important dynamical processes. The functions of these processes in estuarine ecosystem have not been understood well yet. The dynamical processes of phytoplankton ecology in maximum turbidity zone of estuary are the distinguishing features of estuarine ecosystem. In recent decades, progress in research on this field has been achieved. The maximum turbidity zone is one of the special dynamical phenomena in tidal estuary. It is the cloudy waters in which the concentration of suspended particular matter (SPM)is higher than that in the upper river and down sea area, and it often moves upper and down regularly in a certain range. Maximum turbidity zone can been found in every tidal estuary in every climate condition in the world, specially it develops very well in part mixing estuary and full mixing estuary. The initial stage research of maximum turbidity zone has been focused on deposition dynamics in estuary, then on the characteristic and regular pattern of geochemistry. In recent years, the research has been focused on its biogeochemistry, ecology and environment. The results indicated that the maximum turbidity zone has the function of enriching heavy metals and other pollutants. The pollutants can be absorbed by phytopla
