摘　　要：1992～1993年4个航次的调查研究结果表明，九龙江河口区总磷的分布和转移受悬浮物含量明显控制。当SPM含量低时，其迁移过程接近理想行为；SPM含量高时则为非理想行为。估算得出，九龙江水体总磷的平均人海通量为1．47×103t／a。其中，溶解态磷为0．43×103t／a，约占29％；颗粒态磷占71％，九龙江水磷的输入以颗粒态为主。溶解态磷的分布，基本上在某一水平上了波动，其入海通量受环境影响很小，可能意味着颗粒磷的缓冲作用。Based on the investigation data in the four cruises during 1992 to 1993,the transfer and input flux of phosphorus from Jiulong River have been studied. The results indicate that the distribution and transfer of phosphorus in the area are significantIy governed by the suspended particulate material(SPM). Phosphorus is transferred conservatively when SPM content is low and non-conservatively as SPM is high. The input flux of total phosphorus from Jiulong River, estimated from different cruises, ranges between(0. 66~2. 19)×103t/a with an average of 1.47×103t/a. The flux of dissolved phosphorus ranges between(0. 37~0. 48) ×103t/a with an average of 0. 43 ×103t/a and accounts for 29% of the total input;while particulate phosphorus ranging over (0. 29~ 1. 71 ) ×103t/a with an average of1. 04×103t/a,accounts for 71 % of the total input,indicating that the input of phosphorus from Jiulong River ls dominated by particulate form. The distribution of dissolved phosphorus in water fluctuates at a certain level and its flux is less affected by environmental conditions, implying a buffer fuction of particulate phosphorus
