介绍了有关比利时土壤和古土壤微形态的文献研究。比利时的大多数土壤在第四纪覆盖层中发育，北部为沙质，南部变得更加粉质，并与或多或少重要的基质材料混合。此外，非地带性土壤出现在最近的沙丘、海洋圩田和冲积地区。主要成土微形态特征为生物扰动、粉质物质较多的粘土淋积特征、砂质物质较多的斯片状特征。海绿石在成土过程中发挥着重要作用。在大多数剖面中，都认识到与近代成土环境相关的特征，表明多基因土壤的形成。冰缘条件的影响通常是可见的。冲积平原的沼泽矿石具有复杂的矿物成分和微结构。埋藏的古土壤和土壤沉积物根据其年龄分别讨论，而多基因土壤根据其地理位置与现代土壤一起处理。对于某些地区，例如圩田、佛兰德斯的沙区和比利时最南端的高美地区，只有很少的微形态信息。大多数研究的土壤位于自然植被下；对耕地土壤的研究相当罕见。
A study of the literature dealing with micromorphology of Belgian soils and palaeosoils is presented. Most soils in Belgium developed in Quaternary covers, sandy in the north, becoming more silty towards the south, and mixed with more or less important amounts of substrate material. In addition, azonal soils occur in the recent dunes, the marine Polders and the alluvial areas. The main pedogenic micromorphological characteristics are bioturbation, clay illuviation features in the more silty materials, and spodic features in the more sandy materials. Glauconite plays an important role in pedogenesis. Throughout most profiles, features related to a sub-recent pedogenic environment are recognised, pointing to polygenetic soil formation. Impact of periglacial conditions is often visible. Bog ores in alluvial plains have a complex mineralogical composition and microfabric. Buried palaeosoils and soil sediments are discussed separately according to their age whereas polygenetic soils are treated together with the recent soils according to their geographic position. For some areas, e.g., the Polders, the sandy area of Flanders and the Pays de Gaume in the southernmost part of Belgium, only little micromorphological information is available. Most soils studied were situated under natural vegetation; studies of cultivated soils are rather rare.
