前言陆源悬浮碎屑矿物是近岸海水组成的个一重要供给因素。近岸海水的盐度比近海海水低,而悬浮体的浓度却距岸越近越高;盐度和悬浮体的浓度在河口和海岸带呈反比关系。已有人根据河流流量估算了近岸水域悬浮体中碎 Preface Terrestrial suspended detrital minerals are an important contributor to the composition of coastal seawater. The salinity of nearshore seawater is lower than that of offshore seawater, while the concentration of the suspended sediment is closer to the shore. The concentrations of salinity and suspended sediment are inversely proportional to the estuarine and coastline. It has been estimated from the river flow suspended in the nearshore waters
