Digital Heihe

Grain size distribution of soil particles dataset of the Heihe basin

The source data of this data set comes from the 1:1 million soil map of China (Shi et al., 2004) and 8595 soil sections in the second Soil Census. The polygonal connection method is used to connect the soil profile with the soil map to obtain the soil sand, silt and clay content map. The distance between the profile and the map spot, the number of soil profiles and the information of soil classification are taken into account. Please refer to related papers and web pages for specific instructions.
