During the midstream test in 2012, the soil profile was stratified sampled near the meteorological station and brought back to the laboratory for soil parameter measurement. The measured soil parameters include soil texture, porosity, bulk density, saturated hydraulic conductivity and soil organic matter content. Soil parameters are important parameters in land surface process model and vegetation model. These observation data can provide support for the application of the model in the middle reaches of Heihe River
Observation sites: 1-17 meteorological stations (except point 4), shenshawo station, Gobi station, desert station and 50 observation points of waternet in the matrix. The soil sampling coordinates of the meteorological station are shown in the table below
