description The invention provides an in-situ monitoring soil freeze-thawing device and a method for testing the soil carbon loss on the basis of the device, and aims at solving the problems that the existing wild method can only be used for monitoring the carbon discharge flux of a whole soil ecological system and cannot be used for monitoring the contribution of a specific soil layer to the carbon discharge, and a soil freeze-thawing process cannot be really reflected by indoor freeze-thawing simulation experiments. The soil freeze-thawing device mainly comprises a temperature monitoring instrument, a soil column chamber, an air buffer chamber, a rubber sleeve and an air guide pipe. The method for testing the soil carbon loss comprises the following steps of charging in-situ soil columns of different soil layers into the soil column chamber of the freeze-thawing device; burying the soil columns into corresponding oil layers; in a freeze-thawing period, monitoring the discharge condition of gases CO2 and CH4, and compar
