The present paper deals with the principles and methods of regionalization of soils in China. The soil resources of the whole country may be delimitated into three high level categories i.e. Ⅰ. Great soil region;2. Soil zone;3. Soil region. Firstly, the whole territory of China is divided into four great soil regions based on the main variation of soil features and natural environments, namely, Ⅰ. Allitic great soil region (or ferrallitic great soil region);Ⅱ. Siallitic great soil region;Ⅲ. Arid great soil region;Ⅳ. Alpine great soil region. Under these four great soil regions, different soil zones (or soil belt) are divided mainly according to the zonal soil types and their related bioclimatic conditions. The soil zone is further subdivided into soil regions. Each region represents different soil sequence and related landscapes. The utilization, management and ameliorative measures in a soil region are generally similar.
