摘　　要：1995年3月至1996年2月，逐月从九龙江口的淡水端（盐度为0）到入海端（盐度=30）的全段河口区采取表层水样。测定并计算术作溶解态和颗技态的磷：DIP、DOP、DTP、PIP、POP、PTP和TP。结果表明，河流为九龙江口带来大量的磷。其主要以无机态的PIP、DIP形式存在。不同的季节各形态磷对总磷的贡献不同。在盐度为0～30的河口区，可分为三个区域，总体来说，各形态磷的含量随着盐度值的增加而减少，但三个区的减少速度不同。在河口区，磷发生了明显的迁移，且存在着吸附－解吸的动态平衡过程。Surface water of the Jiulongjiang Estuary was monthly sampled from the fresh water (S= 0)end to the rivter Tnorth (S = 30) during March 1995 to February 1996. The dlssolved and particulate phosphorus were determined or calculated, including DIP, DOP, DTP,, PIP, POP,PTP and TP. The results reveal that the river carries a great quantity of phosphorus into the JiulongJiang Estuary, mainly in inorganic forms of PIP and DIP. The contribution of various forms to the total phosphorus varles in different seasons. The estuary in which salinily varies from 0 to 30 can be divided into three regions. Generally speaking, the content of various phosphorus forms decrease with the increases of salinity,but the decreasing rate is different in the three regions. A significant amount of phosphorus was transferred and a dynamic equilibrium between adsorption and desorption was found in the estuary.
