dc.descriptionUse change and land cover has significant influence on energy flows. Thus, this study aimed to compare the net radiation and soil heat flux on two dates, 19/07/1984 and 25/06/2010 from a locality of river basin Ji-Paraná, Rondônia. To develop the study, an algorithm Surface Energy Balance Algorithm for Land (SEBAL) allowing the estimation of energy flows according to the cover. The model was applied in the study area in a sequence of steps, where the outcome of interest was the net radiation at the surface and the flow of heat in the soil. The results show that on average the net radiation was greater in the scene where the predominant areas of forest, 19/07/1984, since the albedo of the vegetation is lower than in surface of bare ground or with less dense vegetation as observed in the scene 25/06/2010. The values of soil heat flux are larger at the scene of 25/06/2010 and occupy a larger surface due to human action. This shows that the replacement of forest for agriculture, grazing and urbanization are causing decrease the net radiation and increase the flow of heat in the soil, thereby increasing the emission of long wave radiation that affect the surface temperature, air temperature and the hydrological cycle.pt_BR
