珠江口表层沉积物图集（1975、1996、2004、2017）

“2017年珠江口表层沉积物综合考察航次” 由“粤南沙渔13168”执行，于2017年11月12日至11月17日对珠江伶仃洋河口进行表层沉积物采样作业。合计采取表层沉积物样119个。针对所获得数据绘制了伶仃洋河口表层沉积物类型、平均粒径、分选系数和偏度、以及净输运趋势等平面分布图并与1975、1996和2005年的分布进行对比

The 2017 Comprehensive Survey Cruise for Surface Sediments in the Pearl River Estuary was operated by the fishing vessel "Yue'nan Shayu 13168". From November 12 to 17, 2017, surface sediment sampling was performed in the Lingdingyang Estuary of the Pearl River, with a total of 119 surface sediment samples collected. Planar distribution maps covering surface sediment types, mean grain size, sorting coefficient, skewness, and net sediment transport trends in the Lingdingyang Estuary were generated using the acquired dataset, and these spatial distributions were compared with those from the surveys conducted in 1975, 1996 and 2005.
