Soil series is the bottom taxon of the Chinese Soil Taxonomy, which currently has a total of about 3 000 soil series, far short of the estimated total of 30 000. So making up the shortage will remain to be a focus of consummating the Chinese Soil Taxonomy for quite a long time in future. How to describe a soil series is the principal link of defining the soil series and the intuitive concrete expression of all the information related to the soil series. To ensure quality of the description, the Special Project of National Science and Technology Basic Researches, namely, “Investigation of Soil Series of China and Compilation of ‘Chinese Soil Series’ (2008FY110600)” had tentatively worked out a standard for description of soil series, The description of a soil series should encompass the following aspects: (1) name of the soil series, soil family it belongs in, names of its founder and authorizer, and dates it was found and authorized; (2) its spatial distribution and environmental conditions; (3) its characteristics and variation amplitude; (4) photos of its typical landscape and soil profiles and morphological description of its typical pedon; (5) soil series for comparison; (6) overview of utilization performance; and (7) reference soil species. However the standard was still found to have some problems with the criteria for soil series description, calling for clarification or solution. Therefore, while introducing the standard for description of soil series, this paper analyzed the existing problems and their causes, and put forth corresponding, in n attempt to further consummate the standard for describing soil series and make it more scientific, standardized, comprehensive and systematic so as to improve the quality of soil series description.
