摘要:本数据集是基于1994年四川科学技术出版社出版的《四川土种志》整理加工而成,是四川省全国第二次土壤普查的成果。在全国和四川省土壤分类系统的基础上,共整理出25个土类、63个亚类和380个土种,对每个土种的名称、代号、归属、分布、面积、主要性状、典型剖面和生产性能等均作了较规范化的描述和信息化处理。经过专业的信息化整理和补充,本数据集形成6个数据表,包括系统分类、土种基础信息及其分布、典型剖面采样地信息、典型剖面发生层调查特征及其理化性质等信息。该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。

Abstract: The data from Soil types dataset of Sichuan is based on the Second National Soil Survey, China Science Publishing in 1994, is one of the summary of Sichuan 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 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 groups, 63 subgroups , 380 typical profiles, and 1162 soil horizons and physical chemical properties. The dataset is widely used for land degradation assessments, environmental impact studies, soil carbon reserves studies, and as a soil-based data to guide agricultural production.
Keywords: Sichuan; Chongqing; soil type; second national soil survey
