黄河三角洲东营港海域表层沉积物分布特征及其影响因素
Distribution characteristics and influencing factors of surface sediments in Dongying Port of Yellow River Delta
摘要
Abstract
Based on the large-scale sampling of surface sediments in Dongying Port in April 2019 and the hydrological data of different periods,the distribution characteristics of surface sediments in Dongying Port were analyzed,and the variation trend,sediment initiation and influencing factors of surface sediments were discussed.The results show that the surface sediments of Dongying Port are mainly silty sand and sandy silty sand with a median particle size ranging from 0.014 3 to 0.061 6 mm.The average content of sand is 21.7%,that of silt is 64.9%,and that of clay is the least,with an average value of 13.4%.The sediment has been coarsening for many years.The coarsening of surface sediments is related to the reduction of sediment sources,the bank erosion caused by hydrodynamics,the"screening"of sediments and the physical characteristics of sediments.关键词
