| 摘 要： | 在综述基准面基本概念的基础上，从泥沙运动力学角度出发建立了正弦曲线型地层基准面旋回的一维定量理论模型。模型通过沉降速率、基准面旋回曲线、沉积物供给速率曲线以及泥砂的平均粒径和密度等基本属性数据，给出了地层表面高度变化的数学表达式，模拟了地层表面的变化，实现了对于地层的沉积、侵蚀和饥饿沉积的模拟，建立和恢复了地层样式。最后通过起始地层面高度高于、低于和等于基准面三种情况下的稳定地层样式对比，得出了由突发、短暂的地层沉降所打破的旋回沉积平衡易于恢复；而因地层抬升偏离的平衡，其恢复时间相对较长。

| Abstract: | This article established the 1D quantitative theoretical model of base level cycle of sinusoidal curve stratigraphy from the view of fluvial hydrodynamics on the basic of summarizing the notion of base level. The modeling simulated the change of strata surface and sediment of strata, erosion and hungry deposition .the stratigraphic is established and recovered. All the simulation made by modeling the basic data such as sediment velocity,curve shape of base level cycle,curve of sediment supply velocity,avera... |
