摘要
<正> The concentrations of the particulate organic carbon (POC) and its isotopic compositions inthe freshwater in the lower reaches of the Huanghe River were observed for one year period.The annualfluxes of the POC and total carbon of the Huanghe River entering seas were estimated,in combination withthe available data on carbon in the dissolved state in literature.For this study 295 water samples and 115sediment ones from 118 stations were collected on three separate cruises to the Huanghe Estuary and morethan 400 organic carbon isotope data were obtained.After the comprehensive study a new model was con-structed on the dispersion of fine-grained suspended matter entering seas from the Huanghe River in combi-nation with contents of suspended matter,concentrations of POC in water samples and grain size parame-ters,contents of organic carbon in sediment samples.
