【Abstract】 During 1983-1984 a joint investigation of marine geology in the South Yellow Sea was conducted between the Institute of Oceanology, Academia Sinica,China and the Woods Hole Oceanographic Institute, USA. This paper is a preliminary result of the work of Chinese scientists on the suspended matter in winter.Concentration distribution of total suspened matter can be grouped into five areas. The first area is nearby the northern coast of Jiangsu province with the highest concentration of more than 200mg/L in the surface water; the second and the third areas located outside outside the mouth of Changjiang River and the east of Shandong Peninsula with a concentration of 10mg/L and 5mg/L;the central part of the sea and the area between Qingdao city and Haizhou Bay are the fourth and the fifth areas with lowest concentration of less than 2mg/L,Concentration of suspended matter (x) versus transmission of sea water (y) confirms the formula y = 82.321e-0.079x and the coefficient of correlation (k) is -0.88. So it’s easy to obtain the concentration of suspended matter if there is no data of concentration in some points.Microscope datum indicated that the major component of suspended matter consist of terrigenous detrital with finer grain size and coarer biogenetic materials.In the high concentration area the noncombustible portion accounts for about 70-90% or more in total weight and in the low concentration area it is less than 50%. The source of suspended matter is mainly the resuspended matter of sediments,discharges the of rivers is next, the biogenetic material is the least. As for as our inforomation goes,after 2-3 days of wind with 8-9 force the concentration of suspended matter increased 3-7 times in same places.更多还原
