摘要

要重建冰盖和冰川以前的范围和动态,需要了解超越个别地貌类型的过程-形式关系。相反,冰川地貌学家需要以更全面的方式分析大面积的冰川地形,结合冰川地貌和沉积物的整个范围来重建过去的冰川系统,这一学科现在被称为古冰川学。“过去的冰川”解释了如何将航空图像和地形分析相结合用于古冰川学重建。功能日益强大的计算机使编制复杂的数值模型成为可能,这些模型利用我们对冰川学过程的知识和源自冰芯的古气候数据来创建三维冰川和冰盖重建。

8. Glaciers of the past
To reconstruct the former extent and dynamics of ice sheets and glaciers requires a knowledge of process-form relationships that goes beyond individual landform types. Instead, glacial geomorphologists need to analyse large areas of glaciated terrain in a more holistic way, combining the whole range of glacial landforms and sediments to reconstruct glacier systems of the past, a subject now known as palaeoglaciology. ‘Glaciers of the past’ explains how the combination of aerial imagery and landform analysis is used in palaeoglaciological reconstruction. Increasingly powerful computers are making it possible to compile sophisticated numerical models that use our knowledge of glaciological processes and ice-core-derived palaeoclimate data to create three-dimensional glacier and ice sheet reconstructions.
