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，是辽宁省第二次全国土壤普查的成果。我们对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。本数据集可用于土地质量、环境效应、土壤碳汇等相关研究，在农业结构调整、土壤资源合理利用等方面具有重要的指导价值，并为第三次全国土壤普查提供重要参考。", "ds_source": "

The Liaoning Soil Species Gazetteer dataset is compiled and processed based on the \"Liaoning Soil Species Gazetteer\" published by Liaoning University Press in 1991, and is the result of the second national soil survey in Liaoning Province. We standardized, structured, and digitized the distribution range, morphological characteristics, physical and chemical properties, productivity, and other data and information of 237 soil species. The dataset generates 7 data tables to describe soil species information in Liaoning, including soil species classification, soil species basic characteristics, soil species typical profile landscape, soil species typical profile occurrence layer, soil species typical profile physicochemical properties, soil species administrative regional distribution, and city and county names. This dataset can be used for research related to land quality, environmental effects, soil carbon sinks, etc. It has important guiding value in agricultural structural adjustment, rational utilization of soil resources, and provides important references for the third national soil census.
