The study looked at how moisture moves in sloping black soil fields in Northeastern China during the freeze-thaw period. They measured soil temperature and moisture at different depths and locations. The data showed that soil moisture and temperature follow a Gaussian distribution pattern, not a straight line, during this period. The highest soil moisture was found early in the freeze-thaw cycle, when snow melts. Moisture levels increased from the top to the bottom of the slope. The researchers also confirmed a strong link between soil temperature and moisture content. Their findings suggest that a model used to predict soil temperature in this region works well.
