Based on the knowledge of specific heat capacity, the regulation effect of wetland on air temperature is briefly explained.

First, a wetland is defined as a zone with a water depth of less than 6 meters. Obviously, it contains water, and the specific heat of water is much greater than that of land, so it can adjust and slow down the temperature change.

In addition, wetland is one of the three most important ecosystems in the world, which is similar to the temperature regulation of forest, and there are also a large number of vegetation and animals living in it. On the one hand, the respiration of animals and transpiration of vegetation also affect the temperature change.
