The net income of radiant energy per unit area of the earth’s surface (called radiation balance) is mainly divided among the heat flowing to the ground, the heat transferred to the air and the heat for evaporating moisture. Therefore, the heat balance of an area is the balance between radiation balance and the other energy expenditure or compensation caused by its transformation.The heat balance equation of the earth’s surface of an area is expressed as R=Q_A+LB+P, where R is the radiation balance, Q_A the heat exchange between the earth’s surface and underlying soil, LB the evaporation heat dissipation (L the latent heat of evaporation and B the amount of evaporation) and P the turbulent heat exchange between the earth’s surface and the atmosphere.In this paper, while results are summarized of investigations on the components of heat balance of the earth’s surface in China, various methods for determining the components of heat balance are also discussed and analyzed.
