| 摘 要： | 作为深时数字地球项目的底层框架,全球古地理重建模型包括地质历史时期板块的位置和运动轨迹以及地表特征两方面的内容。过去数十年里,基于不同方法、不同资料的全球古地理重建模型不断涌现。综合古地磁学、古生物学、沉积学、地球物理、地球化学以及地球动力学领域的知识与资料解释古地理,并建立起数字化、可修改、随时间演变的模型是当前常见的方法。文章介绍了国内外全球古地理重建模型的构建方法,并比较了六种主流的重建模型(PaleoMap、PLATES、UNIL、GOLONKA、GMAP和EarthByte),旨在为国内相关领域研究提供参考。文章还介绍了数字化全球重建古地理模型在古气候、板块构造驱动力以及盆地演化方面的应用及知识发现。通过对现存模型的介绍,提出展望,希望在深时数字地球计划的框架下整合国内外优秀科学家,重新设计并建立真正统一的四维古地理重建模型。

| Abstract: | Paleogeographic models contain reconstructions on position and motion of the tectonic plates and their surface features, and
serve as the framework for geological history reconstruction in the Deep-time Digital Earth (DDE) Big Science Program. Based on different data and methods, a lot of global paleogeographic models have been proposed in the past decades. Recently, it has become more common to use data from various fields such as paleomagnetism, paleontology, sedimentology, geophysics, geochemistry, and geodynamics to establish a digital, detail-adjustable, and self-evolving model. The current paper reviews the existing methods of global paleogeographic reconstruction models, and conducts a comprehensive comparison of the six main reconstruction models (PaleoMap, PLATES, UNIL, GOLONKA, GMAP, and EarthByte), as a reference for domestic research. We also introduced the applications and knowledge discoveries of reconstructed paleogeographic models in the field of paleoclimate, plate tectonics, and basin evolution. Under the framework of DDE program, a unified four-dimensional paleogeographic model will be reconstructed with efforts from paleogeographic scientists all over the world. |
