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，最大厚度1.38米(即0 - 0.045,0.045 - -0.091,0.091 - -0.166,0.166 - -0.289,0.289 - -0.493,0.493 - -0.829,0.829 - -1.383米)。

This dataset uses soil transfer functions with sand particles, silt particles, clay particles, soil organic matter and bulk density as inputs to estimate soil hydrological parameters, including the parameters of Clapp and Hornberger model and van Genuchten and Mualem model, field capacity and wilting point. The 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. The soil is vertically stratified into 7 layers, with a maximum total thickness of 1.38 meters (i.e., 0–0.045 m, 0.045–0.091 m, 0.091–0.166 m, 0.166–0.289 m, 0.289–0.493 m, 0.493–0.829 m, 0.829–1.383 m).
