The objective of this research was to evaluate the behavior of thermal conductivity in the apparentsurface in caatinga predominantly cactus, especially eunapolis [Pilosocereus gounellei (A. Weber ex K. Schum.)]. The study area was the river basin Taperoá, located in the region of Cariris Velhos in the State of Paraíba. Data were used for temperature and heat flux on the surface of vegetated soil. It used the law of heat conduction, who modeling time series of apparent thermal conductivity of the vegetation was made by Fourier methods, linear regression and polynomial. The results are partial, but antagonistic to literature, and they point out that the heat transfer by conduction in the caatinga has significance and should provide support for parameterization and incorporation of vegetation dynamics in the models are, hydrological, environmental or atmospheric circulation.
