黑河流域数字土壤制图产品（第二版）：土壤有机碳分布数据集(2012-2014年)

按照全球数字土壤制图（GlobalSoilMap.net）标准，将0-1m土壤深度划分为0-5cm、5-15cm、15-30cm、30-60cm、60-100cm 5个层次，根据土壤-景观模型原理，使用数字土壤制图方法制作不同层次的土壤有机碳含量空间分布数据产品。预测方法主要是基于土壤-景观模型，该模型基本理论基础是经典的土壤发生理论，模型将土壤视为气候、地形、母质、生物和时间综合作用的产物。本数据集来源于黑河流域重大研究计划集成项目（黑河流域土壤数据集成与土壤信息产品生成，91325301）集成的土壤剖面数据。

Following the standards of Global Digital Soil Mapping (GlobalSoilMap.net), the 0-1m soil depth is divided into 5 layers: 0-5cm, 5-15cm, 15-30cm, 30-60cm, and 60-100cm. Based on the principles of the soil-landscape model, spatial distribution data products of soil organic carbon content for each layer were produced using digital soil mapping methods. The prediction approach is primarily grounded in the soil-landscape model, whose fundamental theoretical basis is the classic soil genesis theory, which regards soil as the product of the combined effects of climate, topography, parent material, biota, and time. This dataset is derived from soil profile data integrated by the integrated project of the Major Research Plan of the Heihe River Basin (Soil Data Integration and Soil Information Product Generation in the Heihe River Basin, Grant No. 91325301).
