广东土种志——基于全国第二次土壤普查数据集
A database of soil species in Guangdong:Based on the Second National Soil Survey
【摘要】 本数据集来源于1996年科学出版社出版的《广东土种志》。该书第一次较详细、系统、全面介绍了广东省212个土种的归属、名称,面积与分布、主要理化性状、典型剖面特征及其理化分析结果、生产性能及改良培肥途径等,是广东省第二次土壤普查的主要成果之一。本数据集在进行系列标准规范化工作的基础上,构造了一个包括地点与土壤类型分布关系和中国土壤发生分类的分类关系的E-R数据模型,形成了具有16个土类、39个亚类、212个土种、212个典型剖面的700个发生层及物理化学性质的数据产品。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,对因土种植、因土施肥、因土改良、调整农业结构布局、合理利用土壤资源等均具有非常重要的指导意义。
【Abstract】 The database is processed from Soil Type Database of Guangdong published in 1996 by Science Press which is based on the Second National Soil Survey. It compiles information on the distribution, area, main characters, land-use and product performance of 212 soil species in Guangdong. After a series of standardization, an E-R data model is constructed which includes relations between location and soil type, and classification relations according to Genetic Soil Classification of China. It results in a data product which contains 16 soil groups, 39 subgroups, 212 main soil species, 212 typical profiles, 700 soil horizons and their physical-chemical properties. The database can widely be used for land degradation assessments, environmental impact studies, soil carbon reserve studies, or to guide agricultural production.
