面向陆面过程模型的中国土壤水文数据集

本数据采用土壤转换函数以砂粒、粉粒、粘粒、有机质、容重作为输入估计出土壤水文参数，包括Clapp and Hornberger函数和van Genuchten and Mualem函数的参数、田间持水量和凋萎系数。中位数和变异系数(CV)提供的估计。 数据集为栅格格式，分辨率为30弧秒，土壤垂直分层为7层，最大厚...

This dataset employs pedotransfer functions with sand, silt, clay, organic matter, and bulk density as input variables to estimate soil hydraulic parameters, encompassing the parameters of the Clapp and Hornberger model and the van Genuchten and Mualem model, as well as field capacity and permanent wilting point. Estimation results are provided with median values and coefficient of variation (CV). The dataset is in raster format with a resolution of 30 arc-seconds, and the soil profile is divided into 7 vertical layers with maximum thickness...
