青藏高原草地土壤pH空间分布图（2019-2022）

土壤pH值（Potential of Hydrogen）数据集，源数据来自于Shuttle Radar Topography Mission (SRTM) 的数字高程数据、Harmonized World Soil Database (HWSD) 的土壤数据以及European Centre for Medium-Range Weather Forecasts (ECMWF) 的气象数据，经过镶嵌、裁剪、重采样等预处理，提取相关地形、土壤、气象因子数据作为特征向量，利用随机森林回归（Random Forest Regression，RFR）模型反演青藏高原地区pH的空间分布，模型精度为93.13%，现有格式为TIFF格式，投影为GCS_WGS_1984。空间范围为整个青藏高原的草地区域，数据空间分辨率为1km。

Soil pH (Potential of Hydrogen) dataset. The source data is derived from digital elevation data of the Shuttle Radar Topography Mission (SRTM), soil data of the Harmonized World Soil Database (HWSD), and meteorological data from the European Centre for Medium-Range Weather Forecasts (ECMWF). After preprocessing procedures including mosaicking, clipping, and resampling, relevant topographic, soil and meteorological factor data were extracted as feature vectors. The Random Forest Regression (RFR) model was employed to invert the spatial distribution of soil pH across the Qinghai-Tibet Plateau, achieving a model accuracy of 93.13%. The current data is stored in TIFF format with the projection of GCS_WGS_1984. The spatial coverage is the entire grassland area of the Qinghai-Tibet Plateau, and the spatial resolution of the dataset is 1 km.
