2002年甘肃省石羊河流域土壤特征参数数据集

本数据集为甘肃石羊河流域不同土壤剖面不同深度土壤性质观测数据，包含土壤黏粒、粉粒、粗砂粒、饱和含水率、干容重、有机质含量、饱和导水率、电导率及根据粒径分布获得的土壤质地和质地类型。数据集还包括根据室内入渗试验数据拟合Kostiakov模型参数、根据土壤特征曲线试验数据拟合GHM模型土壤特征曲线参数。数据集包含石羊河流域平原区30个采样点,其中民勤县12个点，凉州区9个点，古浪县8个点，天祝县1个点，采样时间为2002年。

This dataset contains observational data on soil properties at different depths of various soil profiles in the Shiyang River Basin, Gansu Province. It includes soil clay particles, silt particles, coarse sand particles, saturated water content, dry bulk density, organic matter content, saturated hydraulic conductivity, electrical conductivity, as well as soil texture and soil texture type derived from particle size distribution. The dataset also includes the parameters of the Kostiakov model fitted based on laboratory infiltration test data, and the soil characteristic curve parameters of the GHM model fitted based on soil characteristic curve test data. There are 30 sampling points in the plain area of the Shiyang River Basin, including 12 in Minqin County, 9 in Liangzhou District, 8 in Gulang County and 1 in Tianzhu County. The sampling was carried out in 2002.
