南黄海表层沉积物粒度特征季节变化及其影响因素
Seasonal variations and influencing factors of the grain size characteristics of surface sediments in the South Yellow Sea
摘要
Abstract
We have analyzed graln sizes of 27 surface sediment samples collected from the same stations in the South Yel-low Sea in spring and autumn. Combined with hydrological data, the seasonal variations of graln size characteristics of sur-face sediments have been studied, and the influencing factors of the variations have also been discussed according to related literatures. The results indicate that the surface sediments in the South Yellow Sea can be divided into four kinds of types, including silty sand, sandy silt, silt and mud with Folk’s classification. Compared with the results in spring, the sand and silt contents increase while the clay content decreases in autumn. Correspondingly, the mean graln size (Mz) is coarser in au-tumn. The changes of sorting coefficient (σ) and kurtosis (Kµ) are smaller, while the skewness (Sk) is more positively skewed in autumn. Moreover, the seasonal variations show obvious regional differences, which are influenced by the circu-lation system, river discharges and seasonal changes of waves.关键词
