摘　　要：根据野外观测资料,客观地分析了江苏茅家港滩面沉积物磁化率变化及其与粒度的关系。研究结果显示:滩面沉积物磁化率随着向海离岸距离的增加逐渐增大,粒径逐渐变粗;粒径D与磁化率呈正相关关系,粒度φ与磁化率呈负相关关系。研究区中离岸距离增加,滩面沉积物的粒径逐渐变粗,滩面沉积物的磁化率逐渐增大,说明滩面水动力变强。The paper drew susceptibility distributing map and different section chart by the data that we observed on Maojiagang sands,and impersonally analyzed susceptibility distributing,season change and the relation between change of susceptibility and grain-size.We found that with distance to coast increasing,susceptibility decreasing.With distance to coast increasing,and because it enriched weighty mineral,it leaded to susceptibility decreasing and grain-size gradually become bigger,which indicated that water dynamics was strong.
