摘要:

通过系统地回顾国内外“数字土壤”基础——土壤信息系统的发展过程,着重介绍了中国1:100万土壤数据库建设的数据基础和空间数据库的设计。根据项目组的统一要求,建立了全国土纲、土类和亚类的编码,并一一列举了土纲和土类以及部分亚类的编码。最后对土壤属性数据库的建立方法、所包含的内容及相关参数都作了详细的阐述,并对我国土壤数据库建设提出了一些初步的想法。

Abstract:

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.

Key words: soil map, soil database, codes for soil types, soil spatial database, soil attribute database
