本数据集来源于1994 年科学出版社出版的西藏土地资源调查丛书之一《西藏自治区土种志》，它在西藏全国第二次土壤普查成果的基础上编纂而成，包括了西藏土壤分布、主要性状、典型剖面和生产性能。在进行系列标准规范化工作的基础上，构造了一个包括地点与土壤类型分布关系和中国土壤发生分类的分类关系的E-R 数据模型，形成了具有25个土类、53 个亚类、181 个土种的典型剖面的708 个发生层及物理化学性质的数据产品。本数据集可被广泛用于土地质量评估、环境效应研究、土壤碳储量研究等，为合理利用土壤资源提供极具意义的科学支撑。
 

The data from Soil types database of Tibet is based on the Second National Soil Survey,
China Science Publishing in 1994, is one of the summary of Tibet land resources survey. The primary coverage of Soil types database including the distribution of soil type, the area, the main characters, the land-use and the product performance. On the basis of a series of standardization work, an E-R data model was constructed which included the relation between location and soil type, and the classification relation according to Genetic Soil Classification of China. It results in a data product which contains 25 soil groups, 53 subgroups, 181 typical profiles, 708 soil horizons and physical chemical properties. The database is widely used for land degradation assessments, environmental impact studies, soil carbon reserves studies, and as a soil-based data to guide agricultural production.
