 The study examined the seasonal variations of energy balance components on three different surfaces, irrigated cropland, Inca, Waike, Alpine Meadow, a backslash row, AR, and Spurs Forest, Guantan, GT. The energy balance components were measured using eddy covariance, EC, systems, and a large aperture centimeter loss in the Heihar River Basin, China, in 2008 and 2009. The results showed that the main EC source areas were within a radius of 250 meters at all of the sites. The main source area for the loss, with a path length of 2,390 meters, stretched along a path line approximately 2,000 meters long and 700 meters wide. The surface characteristics in the source areas changed with the season at each site, and there were characteristic seasonal variations in the energy balance components at all of the sites. In the dormant season, the sensible heat flux was the main term of the energy budget, while during the growing season, the latent heat flux dominated the energy budget, and an obvious oasis effect was observed at Waike.
