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...

This dataset employs pedotransfer functions to estimate soil hydrological parameters, taking sand content, silt content, clay content, organic matter content and bulk density as input variables. The estimated parameters include those of the Clapp and Hornberger function, the van Genuchten and Mualem function, as well as field capacity and wilting point. Estimates are provided with their median values and coefficient of variation (CV). The dataset is in raster format with a resolution of 30 arc-seconds, and soil...
