An overview of the development process of soil information system in China and abroad, which was the basis of "digtal soils", was conducted systematically, and particularly the establishing basis and the design of spatial database for China's 1:1,000,000 soil database were introduced in detail. According to the regulation of the research group, the codes for soil order, great group and subgroup were designed and were also listed in this article. Then the creation method, main content and corresponding parameters of the soil attribute database were all expounded. Furthermore some preliminary suggestions to the national soil database were also put forward.
