以东营港附近岸滩为例,探讨了影响粉砂质岸滩地貌的影响因素及其作用。东营港附近的粉砂质岸滩,形成时间短、未经长期地质作用,结构较松散,形成及影响因素复杂,冲淤变化速度快,处于极不稳定的状态,动态性很强。东营港附近岸滩的形成与变化受泥沙、黄河水沙的变化、人类活动、海洋水动力等因素影响,东营港岸滩地貌的动态变化快,表现出快速的向海淤积或向陆蚀退。各种因素对粉砂质岸滩地貌的综合作用,影响了东营港附近岸滩地貌的变化。
Taking the bank near Dongying Port as an example, the influencing factors and their effects on the landform of silty bank are discussed. The silt sandy beach near Dongying Port has a short formation time. Without long-term geological effects, the structure is relatively loose with complex formation and influencing factors. The scouring and silting changes rapidly and in a very unstable state with strong dynamics. The formation and change of shore beach near Dongying Port Affected by the changes of sediment and the change of water and sediment of the Yellow River, human activities and marine hydrodynamics, the dynamic changes of the beach landscape in Dongying Port are fast, showing rapid silting up to the sea or erosion to the sea Retreat The combined effect of various factors on the silt shore beach landform has affected the change of beach landform near Dongying Port.
