摘　　要：本数据集是对1992年出版的《甘肃土种志》中的基本信息进行梳理和归纳整理而成,对书中的285个土种的归属及分布、主要性状、生产性能综述、剖面理化性质等原始数据和信息均进行了规范化、结构化和数字化的采集及提取,集成为以土种ID和土种名称为索引的,并有利于开发成线上查询的8个专业主题数据表,包括土种的土壤分类归属、主要土壤类型分布及特征、土种基本信息及分布、典型剖面采样地及发生层信息、典型剖面及土种剖面统计理化性质数据等。集成的甘肃土种志数据集,可被广泛用于区域土地质量评估、生态环境恢复和土壤科学研究等,为推广农业新技术和合理利用土壤资源提供科学支撑。Based on the results of the Second National soil Survey,Gansu Soil Species was established to accumulate systematic,standardized and quantitative data of soil classification as a solid foundation for the development of soil science in Gansu province.This dataset is based on the processing and integration of Gansu Soil Species published by Gansu Science and Technology Press in 1992.The original data and information of 285 soil species in the book(e.g.attribution and distribution,main characters,production performance summary,physical and chemical properties of profiles)are extracted and collected in a standardized,structured and digital way,integrated with 8 specialized subject data tables indexed by species ID and species name,and conducive to the development of online query,including soil species classification,distribution and characteristics of main soil types,basic information and distribution of soil species,sampling sites and occurrence layers of typical profiles,statistical physicochemical properties of typical profiles and soil species profiles,etc.This dataset can be widely used in regional land quality assessment,environmental effect research,soil carbon storage research,etc.,providing significant scientific support for the promotion of new agricultural technology and rational utilization of soil resources.
