| 摘 要： | 沉积模拟实验表明，砂质扇三角洲侵蚀-沉积过程从扇三角洲平原开始，经历了直河道沉积、侵蚀-河口坝形成、滑塌-分流点向上迁移、砂坝生长-辫状河道废弃-形成新朵体的过程。基准面变化对扇三角洲影响明显：基准面上升，扇三角洲沉积厚度增加。但平面形态及展布范围变化较小；基准面下降，展布范围增大，并出现新的扇三角洲朵体。

| Abstract: | Sedimentary simulation experiment shows that the encroached-sedimentary process of sandy-fan-delta starts from fan-delta plane,which experiences straight channel, forming of encroached-debouch bar .upper transferring of slum-ping-shunting point, sandy bar growing, braided channel abandoned and forming new lobes. It is obvious that the change of base level would influence the fan-delta: when the base level rises, sedimentary thickness of the fan -delta increases, but the plane configuration and range of distribution have less changing. When the base level descends, range of distribution increases and new fan-delta lobes appear. |
