Based on systematically sorting out the data of 879 soil species at the provincial (prefecture, city) and county levels, this data set is compiled by combing and summarizing 37 soil categories, 100 subcategories, 171 soil genera and 305 soil species. It is one of the series achievements of the second national soil survey in Gansu Province. The book introduces the name, attribution, distribution, area, main properties, typical profile, production performance summary and physical and chemical analysis data of main soil species in Gansu in the soil classification system. In the process of compiling, because some soil species data are still insufficient, there are only 285 written words, of which 4 are still incomplete after review, and the appendix is attached. The establishment of Gansu soil chronicles accumulates data for the systematization, standardization and quantification of Gansu soil classification, and lays a solid foundation for the development of Gansu soil science\n
& emsp; Based on Gansu soil species annals, this data set collects and extracts all the original data and information of 285 soil species in the book in a standardized, structured and digital manner. After sorting and processing, it is integrated into 8 professional subject data tables, including soil classification and attribution distribution of soil species, distribution and characteristics of main soil types, basic information and distribution of soil species Typical profile sampling site and occurrence layer information, typical profile and soil type profile statistical physical and chemical properties and other data. The soil type ID is the primary key between each data table, which is convenient for development as an online retrieval and query mode.
