| 摘 要： | Based on the author’s previously obtained results on P and Si forms in southern Bohai Sea surface sediments,this study maindy foucusing on the controlling factors,existence forms,and biogeo-chemical processes of P and Si showed that the transferable forms of phosphorus in sediments were mainly controlled by the mineralization of organic matters and the reduction of high-valence iron;whereas the transferable forms of silicon were possibly controlled by the dissolution and precipitation as well as bio-chemical processes of living organisms.
