摘要

摘要: 研究了胶体磷在河口海区随盐度变化的趋势,并将其与颗粒态、真溶解态磷随盐度的变化趋势进行对比,分析胶体态磷在河口的行为与颗粒态磷和真溶解态磷二者的异同。探讨磷在颗粒相、胶体相和真溶液相之间的分配及其与悬浮颗粒物浓度的关系,研究胶体磷在河口海区中的迁移转化作用。研究结果表明,胶体相中总磷、有机磷和活性磷浓度由河端向海端降低,表明陆源输入是其主要来源。胶体有机磷占总磷比例随盐度增加而下降,表明有机磷受胶体去除过程的影响较明显,胶体磷在河口海区的浓度变化趋势及胶体中有机磷和活性磷的比例都与真溶解相接近而与颗粒相差别较大。

Abstract: The variation of colloidal phosphorus with salinity in esturary was studied,which was compared with that of particle and truly dissolved phosphorus with the purpose of finding out the similarities and differences between behaviors of them. Distribution patterns of phosphorus in particle,colloidal and truly dissolved phase under different salinities and their relationships with suspended particulate matter were also researched to understand the transformation and transportation of colloidal phosphorus in estuarine area. The result shows that the concentrations of total colloidal phosphorus,organic colloidal phosphorus and inorganic colloidall phosphate all descend from river-end to sea-end,illust rating their terrigenous source1 Ratios of organic to total colloidal phosphorus decreased with salinity,indicating that organic phosphor us was influenced by scavenge process of colloid more significantly compare with inorganic phosphate. Both of the phosphorus variation tendencies and the proportion between organic and inorganic phosphorus in colloidal phase were similar with that in truly dissolved phase while different from that in particle phase.
