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。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 dataset based on the Second National Soil Survey published by China Science Publishing in 1994,is one of the results of the Second National Soil Survey in Sichuan Province.On the basis of the national and Sichuan soil classification system,we sorted out a total of 25 soil groups,63 subgroups and 380 soil types,and made standardized description and information processing for the name,code,attribution,distribution area,main characters,typical section,production performance of each soil type.Through professional informatization and supplementation,this dataset has 6 data tables,including system classification,basic soil type information and its distribution,typical section sampling site information,the survey characteristics of the typical section occurrence layer,its physical and chemical properties,etc.The dataset can be widely used for land degradation assessment and the research on environmental impact and soil carbon reserves,provide scientific support of great significance for the rational use of soil resources.
