摘　　要：为了评价物质入海通量对地区的影响,有必要对入海通量进行统计分析,并对其控制因子进行研究。由于机制分解方法物理概念清晰,采用此方法。从物质平衡入手,分析物质输运机理,描述不同类型河口的特点,并在实测资料的基础上,研究珠江口内伶仃洋河口湾的盐度输运,对比各动力因子对盐度贡献项的大小,结果表明盐度纵向净通量主要是由纵向净平流输运控制,斯托克斯漂移和垂向净环流引起的盐度输运也不容忽视。In order to evaluate the effect of the material flux which goes into the sea on the areas, it is necessary to make statistical analysis of the sea flux, and to research its control factor. As the decomposition concepts of are clear, this method is applied in this paper. Based on the material balance, material transport mechanism is analyzed, and different types of the characteristics of the estuary is described. And on the basis of the measured data, salinity transport in the internal Lingdingyang firth of the Pearl River mouth is researched, and the dynamic factors contributing to the salinity is compared. The results showed that a salinity vertical net flux is mainly controlled by the vertical net stratospheric transport, salinity transport caused by stokes drift and vertical net circulation should not be overlooked.
