摘　　要：土壤微形态学从上世纪二十年代发展至今,取得了很大的进步,并广泛应用于土壤学各个领域,解决了很多土壤学问题。越来越多的学者应用微形态学方法进行土壤形成演化和系统分类研究,并取得了很好的结果。近年来中国土壤系统分类研究取得了长足的进步,在开展土壤系统分类制的基层分类上,应当把土壤微结构作为重要依据,以丰富土壤基层分类的内容,提高我国土壤系统分类在基层分类研究和应用上的水平。本文试从土壤形成演化和土壤系统分类中土壤诊断层和诊断特征两方面叙述土壤微形态学的应用。特别是总结了中国土壤系统分类中人为土、富铁土、变性土及其它土纲应用土壤微形态的研究成果。最后提出加强人为土、土壤基层分类的微形态研究以及土壤微形态的动态定量研究是土壤系统分类中土壤微形态学发展的重要趋势。Soil micromorphology had made great progress since 1920s,and it had been widely used in various fields to resolve plenty of problems of soil science.More and more scientists applied soil micromorphology to research soil genesis and soil taxonomy,and had obtained convincible results.In resent years,considerable progress had been made in Chinese Soil Taxonomy,soil micromorphology should be as important evidence to enrich basic soil taxonomy and enhance the status of basic soil taxonomy.This paper summarized the application of soil micromorphology to soil formation and evolution and soil diagnostic horizon and characteristics of soil taxonomy,especially Anthrosols,Ferrosols,Vertosols in Chinese Soil Taxonomy.Finally,important trends of soil micromorphology were pointed out.
