摘　　要：作为连接深时地球内外系统的关键界面,重建的古地貌为跨圈层耦合、多学科交叉研究提供了重要途径。地球系统理论的进步以及计算机模拟技术的发展,使得深时古地貌动态重建成为可能。近年来,Badlands(Basin and Landscape Dynamics)区域古地貌模拟软件和goSPL(Global Scalable Paleo Landscape Evolution)全球古地貌模拟软件的开发,将地球深部构造过程、降水、海平面变化等若干地球系统因素联系起来,为理解地表系统演化及其与地球固体圈层相互耦合提供了新的技术基础。基于这些新兴模拟技术,聚焦东亚地形倒转和水系重组、显生宙古地貌演变与海洋物种多样性关系等问题,国内外学者分别已开展了相关模拟工作并取得了很好的研究成果。但鉴于高程代用指标本身的不确定性,不同古地貌重建模型之间存在差异;此外,这些古地貌重建模型很难做到与高精度的地质观测记录完全吻合,迫切需要开展超高(时间和空间)分辨率的海陆古地貌重建。As a key interface connecting the deep-time Earth's internal and external systems,paleo-landscape reconstruction provides an important way for studying deep Earth sciences.The development of computer simulation tools makes it possible to reconstruct deep-time dynamic paleo-landscape.Badlands(Basin and Landscape Dynamics)and goSPL(Global Scalable Paleo Landscape Evolution)software are designed to understand the evolution of surface Earth system and its interaction with the solid Earth system,by combining factors of different spheres such as deep tectonic process,precipitation and sea level change.Based on these new technical basis,some achievements have been made,e.g.regional models that reproduce the topographic inversion and drainage reorganization processes in East Asia and global models that couple the landscape dynamics with the Phanerozoic diversification of the biosphere.However,some differences among different paleo-landscape reconstruction models arise due to uncertainty in elevation proxy indicators.In addition,it is difficult to make the simulated results to be completely consistent with the high-precision geological observation records.It is urgent to carry out global paleo-landscape models of ultra-high resolution in time and space.
