摘    要:本文通过百花湖沉积物柱芯不同化学相磷含量分布,孔隙水地球化学及早期成岩模式和通量估算等研究,揭示了磷在早期成岩过程中迁移,转化和富集规律,揭示某些湖泊表层沉积物几厘米磷蓄积浓度的增加与磷在早期成岩过程中的行为有关。

关 键 词:沉积物,水界面,磷的再迁移作用,百花湖

Abstract:Many investigations during the past 20 years have showed that P concentration increas-ing at the top surface sediments of lakes possibly resulted from agricutural activites andwaste pollution,but it's not known if this phenomena had some relationship with early dia-gensis, choosing a small lake built up 30 ago, which P pollution of its watershed has beendecreasing recently, thorough studying the profiles of P chemical species in the sedimentsand porewater, diffusion flux and modelling calculation of P remobilization, and influenceextent of early diagensis on P profiles, the paper discribled P enrichment and mobilizationprocesses in the surface sediments during early diagensis.
Keywords:early diagensis  remobilization  enrichment  lake baihua
