摘要
土壤基层分类单元划分,特别是土系建立是土壤系统分类的基础,也能直接为农业生产提供更详细的科学指导。富铁铝化土壤(砖红壤、赤红壤和红壤)在我国南方广泛分布,为了解其在中国土壤系统分类中的归属以及土系建立情况,本文综述了自2008年以来土系研究的相关成果,系统分析了富铁铝化土壤诊断层和诊断特性检索、高级分类单元归属以及基层分类单元建立现状,并展望了土系建立的发展方向:进一步细化土系划分和描述标准,加强新土系建立,加强新技术和新方法在土系建立中的应用,加大和扩展土系建立成果的运用,以为我国南方富铁铝化土壤系统分类研究提供参考。
The study of soil basic taxon,especially soil series establishment,is a foundation of Chinese Soil Taxonomy(CST),and can directly provide scientific guidance for agricultural production.The ferrallitic soils(Latosol,Latosolic red earth,red earth)are widely distributed in southern China.In order to understand the progresses of attribution and soil series establishment of ferrallitic soils in CST,the paper reviewed the achievements of the National S&T Basic Special Foundation Project"Survey of Soil Series in China and Compilation of Soil Series of China"since 2008,in which the retrieval consequences of diagnostic horizons and characteristics and attribution of higher taxa and soil series establishment of ferrallitic soils were systematically analyzed,the future development of soil series establishment should focus on the refining the criteria of partitioning and describing soil series,strengthening the establishment of new soil series,utilizing the updated technology and method,and broadly capitalizing on the achievements.These advances would be a reference for researching soil taxonomy of ferrallitic soils in southern China.
