A series of the micrometeorological observations have been carried out on the slopes have of the hilly region of the southeastern part of the Loess Plateau over a two year period from ray 1989. Heat balance on the surface of the slopes which face north and south are roughly estimated from the data of solar radiation, air and soil temperatures and air humidity etc.The results of these observations show that the direction and gradient of the slopes remarkably affect thermal environments, temperature and soil freeze of the ground in winter. The numerical models of heat flow through the ground, vegetation and boundary layers were applied to estimate the thermal conditions on the slopes. The results calculated from the numerical models are substantially in accord with the observed ones.
