摘要地质时间跨度上碎屑沉积体系的物理模拟必须诉诸模拟模拟，因为在实验室设置所施加的空间和时间限制内无法实现全比例。这种相似模型适合于通过分离控制参数来系统地研究沉积体系对异旋回变化的敏感性。到目前为止，景观演变的模拟模型主要是定性的。在本文中，我们提出了一个定量的方法。定量实验结果进行了验证和讨论，通过与高分辨率的数据从科罗拉多河架系统的得克萨斯州的货架，我们作为一个原型。
ABSTRACT Physical modelling of clastic sedimentary systems over geological time spans has to resort to analogue modelling since full scaling cannot be achieved within the spatial and temporal restrictions that are imposed by a laboratory set‐up. Such analogue models are suitable for systematic investigation of a sedimentary system's sensitivity to allocyclic changes by isolating governing parameters. Until now, analogue models of landscape evolution were mainly qualitative in nature. In this paper, we present a quantitative approach. The quantitative experimental results are verified and discussed by comparison with high‐resolution data from the Colorado river–shelf system of the Texas shelf that we used as a prototype.
