In this paper, through the analysis of the structure of airport concrete pavement surface, thermal properties, thermal properties, air parameters, solar radiation, atmosphere long wave radiation, obvious heat exchange and latent heat exchange of background and other factors, this paper build one dimension ground temperature field model. Then, we find finite element method solution of the model by ANSYS, get the temperature contours of the airport road surface, so as to provide theoretical support for the airport equipment of infrared stealth design, camouflage to guide the practice of airport equipment, camouflage effectiveness evaluation.
