| 摘 要： | 对位于浙-闽沿岸泥质带的EC2005孔沉积物粒度分形特征以及与平均粒径和分选系数的关系进行了探讨.EC2005孔沉积物粒度在累积含量5%～95%的无标度区间内,统计自相似程度高,具有分形特征.沉积物平均粒径与分维值既存在正相关,也有负相关关系.二者正、负相关关系的分界点表现为平均粒径7.0φ左右,＜7.0φ时,平均粒径... |

| Abstract: | This study discussed the fractal features of grain size distribution of the core sediments from the depocenter of the Zhejiang-Fujian mud wedge on the inner shelf of the East China Sea(ECS),and the correlation between mean grain size and sorting coefficient.The EC2005 sediment grains falls within the fractal scaleless zone of cumulative percentage between 5% and 95%.The core sediment is characterized with high self similarity and(or fractal) grain-size distribution.The mean grain sizes of the sediments are ... |
