摘要。土壤的形成是一个复杂的生物网络以及化学和物理过程的结果。土壤微生物的作用引起了人们的高度关注，因为它们负责大多数生物转化，并推动稳定和不稳定的碳(C)、氮(N)和其他营养物质库的发展，从而促进随后植物群落的建立。冰川消退前田提供了不同土壤发育阶段的独特时间序列，是研究细菌、真菌和古细菌与其非生物环境相互作用的理想生态系统。本文综述了微生物在土壤发育中的作用。本文给出的结果基于合作研究计划DFG SFB/TRR 38 （http://www.tu-cottbus.de/ecosystem）进行的研究，并辅以其他研究的数据。综述了土壤形成主要步骤的微生物学。特别关注营养循环在生物土壤结皮（BSCs）形成中的发展以及植物与微生物相互作用的建立。
Abstract. Soil formation is the result of a complex network of biological as well as chemical and physical processes. The role of soil microbes is of high interest, since they are responsible for most biological transformations and drive the development of stable and labile pools of carbon (C), nitrogen (N) and other nutrients, which facilitate the subsequent establishment of plant communities. Forefields of receding glaciers provide unique chronosequences of different soil development stages and are ideal ecosystems to study the interaction of bacteria, fungi and archaea with their abiotic environment. In this review we give insights into the role of microbes for soil development. The results presented are based on studies performed within the Collaborative Research Program DFG SFB/TRR 38 ( http://www.tu-cottbus.de/ecosystem ) and are supplemented by data from other studies. The review focusses on the microbiology of major steps of soil formation. Special attention is given to the development of nutrient cycles on the formation of biological soil crusts (BSCs) and on the establishment of plant–microbe interactions.
