%X Based on the observations on energy balance in winter wh eat fields with different water treatments in Shunyi County,Beijing,the daily an d diurnal variations of energy partitioning, albedo and CO 2 fluxes over the di fferent water treating fields are compared and analyzed. The results show that t he daily mean albedo is about 0.18during the jointing period, the latent and sen sible heat fluxes show significant difference under different water treatments. The daily variation of CO 2 flux above canopy is a parabola shape and the canop y is a sink of CO 2 in this period.
