以《中国土壤系统分类》 (修订方案 )以及《土壤基层分类试用方案》 (修订稿 )为准则 ,以特征土层为土系主要划分依据 ,建立了覆盖湖北省不同地貌、母质、土壤类型共 75个土系 ,归属于《中国土壤系统分类》 (修订方案 )的 5 5个亚类 ,36个土类 ,1 7个亚纲 ,1 0个土纲。土系的建立是以明确的形态理化特征为指标 ,具有定性、定量、定型和区域定位的特征。土系以地名命名且用“双名法”过渡 ,便于土壤信息交流与共享
Based on the “Soil Taxonomy in China” (revised plan) and the “Soil Grassroots Classification Trial Plan” (revised draft) as the guidelines and the characteristic soil layer as the main classification basis of soil system, a system was established to cover different types of landforms, parent materials and soil types in Hubei Province 75 soil systems, belonging to 55 sub-categories, 36 soil types, 17 sub-classes and 10 soil classes of the “China Soil System Classification” (revised plan). The establishment of soil system is based on the clear physical and chemical characteristics of the shape as an indicator, with the characteristics of qualitative, quantitative, stereotyped and regional positioning. Soil system named after the place names and “double name method” transition, facilitate soil information exchange and sharing
