Rivers with fluvial equilibrium are characterized by bed deformation adjustment. The erosion-deposition area in cross-section can reflect this characteristic. The time series of erosion-deposition area in BYGL and SHHK stations was obtained by quantifying change of section area during the period 1976-2006. After trend and mutation analysis, three different trends were identified in general: the quasi-equilibrium phase, rapid shrinkage phase and the new quasi-equilibrium phase. It was also found that once a big flood occurred in the ten tributaries, the trend of erosion-deposition area would change. The phenomenon was more obvious due to the decrease of deluge after the completion of upstream reservoir. After the time series had clear mutations in the late 1990s, the Inner Mongolia reach entered a new equilibrium phase. The conditions of incoming water and sediment were adapted to the bed boundary conditions. Therefore, how to control sedimentation in Inner Mongolia reach was worth discussing.
