Datasets description

The simulated distribution map of frozen soil in the upper reaches of the Heihe River was obtained by spatially interpolating the surface temperature at 0cm from nine stations inside and outside the source area of the Heihe River from 1993 to 2012, combined with frozen soil simulation methods. In the figure, 1 represents seasonal frozen soil and 2 represents perennial frozen soil.
