黑河数字土壤制图产品：土壤质地（粒径组成）空间分布数据集（2012-2016）

选取土壤表层深度0-20cm土壤机械组成数据，选择最优的土壤成分数据空间预测制图方法，制作土壤质地（粒径组成）空间分布数据产品。土壤粒级划分标准使用美国制分类法。本数据集的源数据来源于寒区旱区数据中心，以及黑河流域重大研究计划集成项目（黑河流域上游植被及其环境要素空间插值与动态模拟分析/批准号91325204）集成的土壤采样数据。

We selected soil mechanical composition data from the 0–20 cm topsoil layer, adopted the optimal spatial prediction and mapping method for soil property data, and produced spatial distribution data products of soil texture (particle size composition). The soil particle size classification follows the United States Department of Agriculture (USDA) standard. The source data of this dataset is obtained from the Cold and Arid Regions Data Center, as well as soil sampling data integrated by the Integrated Project of the Major Research Plan of the Heihe River Basin (Spatial Interpolation and Dynamic Simulation Analysis of Vegetation and Its Environmental Factors in the Upper Reaches of the Heihe River Basin / Approval No. 91325204).
