【摘要】 沉积物的粒度分析是海洋学研究的重要手段。以黄海、东海中187个沉积物采样点的矢量数据为基础,运用地统计学方法对研究区域内沉积物组分和粒度参数的空间变异性进行分析,并在此基础上绘制出沉积物粒度的空间分布图。结果表明:沉积物组分和粒度参数在黄海、东海海域表现出较强的空间自相关性。在各项异性特征上,沉积物粒度大多在小范围内表现出显著的各项异性特征,除了粉砂之外,其余组分及参数在大于120 km范围上的各项异性特征趋于明显。本研究结果对理解黄海、东海海底地貌动力过程具有科学意义,也对海洋环境评价、海底管道铺设等实际应用有一定的指导作用。更多还原

【Abstract】 Sediment grain size is an important tool for oceanographic research.Based on the vector data of 186 sediment sampling points in the Yellow Sea and the East China Sea,the study analyzes the spatial variability of sediment composition and grain size parameters in the area by geostatistics methods,and then drew the spatial distribution map of the granularity.The results show that the sediment composition and grain size parameters suggest strong spatial autocorrelation in the Yellow Sea and the East China Sea.In the anisotropic characteristics,the sediment particle size mostly shows significant anisotropic characteristics in a small range.Except for silt,the anisotropic characteristics of other components and parameters over 120 km tend to be obvious.This result has a great effect on understanding the dynamic process of submarine geomorphology in the Yellow Sea and the East China Sea,also plays a certain guiding role for practical applications such as marine environmental assessment and submarine pipeline laying.更多还原
