【Abstract】 This paper inquires into the relation of sediment phosphoric contents with water depth, sedimentary type, suspended material, hydrodynamics, and fossils of foraminifera fete by analying, its distribution variation in the sediment samples taken from the western Central Pacific Ocean, the Yellow Sea, the East China Sea, and the offshore area of Northern Jiangsu. The distribution models of phosphoric contents in the oceanic, offshore, and estuarine sediments are diseu--ssed. Meanwhile, the analysis of the core sample shows that vertical distribution variation o?" phosphorus can be used as one of the indexes of paleoclimate.更多还原
