摘　　要：利用2004年冬季对黑泥湾近岸海域悬浮体调查资料及2个时相的遥感影像,探讨了该海域悬浮体的分布和扩散特征,分析了影响悬浮体分布的主要因素和悬浮体的主要物质来源。结果表明,影响本海域悬沙质量浓度及其分布的主要因素是风浪掀沙和潮流。夏季,近岸悬沙质量浓度高,向海逐渐减少;冬季,悬沙质量浓度近岸低,向海逐渐增大。由于本海域没有大的河流泥沙汇入,悬沙的主要物质来源是沿岸侵蚀、冲沟排沙和海底泥沙再悬浮。The suspended sediment concentration and bottom sediments around Heini Bay were collected in winter, 2004. According to the information of suspended matter, bottom sediments and 2 remote sensing images, the distribution and diffusion characteristics of suspended sediment concentrations at surface and bottom layers were studied in the study area, the primary factors effecting the suspended sediment concentration distribution and the origin of them were analyzed. The result shows that the primary factors were wind and tidal flow. The suspended sediment concentration was great in shore in summer, gradually reduces seaward, and it is just contrary in winter. The main matter origins of suspended sediment concentration were from the erosion alongshore, gullied and transportation, resuspending of seabottom sediment.
