基于全国第二次土壤普查的四川重庆土种志数据集

四川重庆土种志数据集是按照科学数据库和土壤学科领域数据实施的标准规范，对《四川土种志》中的相关数据和信息的结构化提取并集成为可查询的数据表。本数据集主要包括两部分内容，共6张数据表组成：（1）包含四川–重庆第二次土壤普查土壤分类、地理分布、土种基本特征信息的3张数据表；（2）包含四川–重庆土种典型剖面采集样地信息、四川–重庆土种典型剖面发生层调查性质和土种典型剖面理化性质3张数据表。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。

Sichuan-Chongqing Soil Series Dataset is developed in accordance with the standard specifications for scientific databases and soil science domain data. It is constructed by structurally extracting and integrating relevant data and information from *Sichuan Soil Series Annals* into queryable data tables. This dataset consists of two parts, totaling six data tables: (1) Three data tables containing soil classification, geographic distribution, and basic characteristic information of soil series from the Second National Soil Survey in the Sichuan-Chongqing region; (2) Three data tables covering information on sampling plots of typical soil series profiles in Sichuan-Chongqing, investigated properties of the genetic horizons of typical soil series profiles, and physical and chemical properties of typical soil series profiles. This dataset can be widely applied in land quality assessment, environmental effect research, soil carbon storage research and other relevant fields, providing valuable scientific support for the rational utilization of soil resources.
