摘　　要：辽宁土种志数据集是基于1991年辽宁大学出版社出版的《辽宁土种志》整理加工而成,是第二次全国土壤普查的成果。本研究对237个土种的分布范围、形态特征、理化性质、生产力等数据和信息进行规范化、结构化和数字化处理。数据集生成7个数据表以描述辽宁土种信息,包括土种分类、土种基础特征、土种典型剖面景观、土种典型剖面发生层、土种典型剖面理化性质、土种行政区域分布以及市县名。本数据集可用于辽宁土地质量、环境效应、土壤碳汇等相关研究,对辽宁农业结构调整、土壤资源合理利用等方面具有重要参考作用。Based on Liaoning Soil Species published by Liaoning University Press in 1991,this dataset is one of the results of the Second National Soil Survey in Liaoning Province.We standardize,structurize and digitalize the data of 237 soil species,organizing them based on their distribution areas,morphologic characteristics,physicochemical properties and productivity.Particularly,the dataset uses seven tables delineating Liaoning soil species,including soil classification,soil basic traits,landscape of typical soil profile,genetic horizon of typical soil,physicochemical properties of typical soil profile,administrative region distribution of soil species,and the names of counties and cities.The dataset can be used for land quality assessment and research on environmental change and soil carbon sequestration in Liaoning Province.The dataset serves as a crucial reference for informing agricultural structure adjustment and facilitating the rational use of soil resources in Liaoning Province.
