全球250米分辨率土壤粉粒含量数据集

该数据集是全球250米分辨率土壤粉粒含量数据，包括不同深度（0-5 cm、5-15 cm、15-30 cm、30-60 cm、60-100 cm和100-200 cm） ，共 6个图层的数据。数据集通过网络挖掘获得，数据来源于ISRIC世界土壤信息中心制作的SoilGrids土壤网格产品，下载于https://www.soilgrids.org/[2021]，经爬取、镶嵌、格式转换等处理过程，形成全球250米分辨率土壤粉粒含量数据。该数据利用全球土壤剖面信息和协变量数据来模拟全球土壤特性的空间分布，使用机器学习以250 m分辨率制作的世界土壤属性地图的集合，土壤属性预测在六个标准深度进行。

This dataset is a global 250-meter resolution soil silt content dataset consisting of 6 layers corresponding to six standard soil depths: 0-5 cm, 5-15 cm, 15-30 cm, 30-60 cm, 60-100 cm, and 100-200 cm. It was obtained via web scraping, sourced from the SoilGrids soil grid product developed by the ISRIC World Soil Information Center, and downloaded from https://www.soilgrids.org/ in 2021. After processing workflows including scraping, mosaicking, and format conversion, the final global 250-meter resolution soil silt content dataset was generated. This dataset is a collection of global soil property maps produced at 250 m resolution using machine learning, which simulates the spatial distribution of global soil properties by leveraging global soil profile information and covariate data, with soil property predictions conducted at the six aforementioned standard depths.
