南极海洋性气候区是南极风化与成土作用相对较强的地区。本文在对本区气候特点进行分析的基础上,明确了冻胀风化是本区最主要的物理风化形式,强烈的现代地貌过程对本区风化与成土过程具有显著影响。阐述了本区内化学风化的主要过程、机制与产物,同时指出生物因素在本区的岩石风化与原始土壤形成过程具有重要意义。
The Antarctic maritime climate zone is a region where Antarctica weathering and soil formation are relatively strong. Based on the analysis of the climatic features in this area, it is clear that frost heave weathering is the most important form of physical weathering in this area. The strong modern landform process has a significant impact on the weathering and soil-forming processes in this area. The main processes, mechanisms and products of chemical weathering in this area are expounded. At the same time, it is pointed out that the biological factors in this area are of great importance to the rock weathering and the formation of primitive soil.
