摘      要：The waters offshore the Shandong Peninsula separate the North Yellow Sea from the South Yellow Sea,and receive a large amount of terrestrial material from Chinese and Korean rivers,making it an ideal area for studying land-sea ***,little attention has been given to measuring sediment transportation in most previous *** on an analysis in composition of major and trace elements and particle size characteristics from 62 surface sediment samples from the northeastern region off Shandong Peninsula,the type,element composition,and controlling factors of the surface sediments were *** addition,the transportation of sediments from source to sink was described from measured thermohaline *** results show two types of surface sediments:sandy silt and *** sediments were mainly terrestrial;and marine carbonate had little effect on sediment *** on a binary diagram of Rb/Sc to Co/Sc,the Huanghe(Yellow)and Changjiang(Yangtze)Rivers are the main sources of surface sediments in the study *** component mixing model showed that the relative contribution of sediment from the Huanghe River was up to 92%,followed by the Changjiang River(8%).The Yellow Sea Warm Current and the North Shandong Peninsula Coastal Current met at∼37.7°N in the study area,and were the main forces carrying sediment from the two main river ***,there was a deficit of transported material into the study area in *** secondary distribution of sediment from the two river sources was controlled by tidal currents and waves.
