A dataset of Heilongjiang soil species based on the Second National Soil Survey

This dataset originates from the systematic collation and processing of the printed content in Soil Species of Heilongjiang, compiled by the Heilongjiang Soil Survey Office and the Heilongjiang Land Survey and Utilization Technology Center in October 1990. As an outcome of the Second National Soil Survey in Heilongjiang Province, this monograph comprehensively merges and organizes data for 254 soil species, including their distribution, main characteristics, overview of production performance, and physic-chemical properties of typical profiles. Based on the information characteristics of soil science and online service requirements, the original data underwent informatization, standardization, and structured extraction to construct seven data tables using soil species codes and names as key indices. These tables cover soil classification information, basic soil species data, landscape information of typical profiles, genetic horizon details of typical profiles, physicochemical properties of typical profiles, administrative distribution of soil species, and administrative codes for cities and counties. The dataset features reliable original data sources and scientific, standardized collection methods. It serves the third national soil survey and is widely applied in fields such as regional land quality assessment, ecological environment restoration, and soil scientific research, providing a solid scientific foundation for the rational utilization of soil resources.

本数据集源自黑龙江省土壤普查办公室与黑龙江省土地调查与利用技术中心于1990年10月编纂的《黑龙江省土壤种（Soil Species of Heilongjiang）》印刷内容的系统整理与加工。作为黑龙江省第二次全国土壤普查的成果之一，该专著全面整合并梳理了254个土壤种的数据，涵盖其分布特征、主要性状、生产性能概况以及典型剖面的理化性质。基于土壤科学的信息特性与在线服务需求，原始数据经过信息化、标准化与结构化提取，以土壤种代码与名称作为关键索引，构建了七张数据表。这些数据表涵盖土壤分类信息、土壤种基础数据、典型剖面景观信息、典型剖面发生层细节、典型剖面理化性质、土壤种行政分布以及市县行政代码。本数据集原始数据来源可靠，采集方法科学规范。其服务于第三次全国土壤普查，已广泛应用于区域土地质量评估、生态环境修复、土壤科学研究等领域，为土壤资源的合理利用提供了坚实的科学依据。
