Abstract: Three important problems about the Lower Yellow River are deeply analyzed. The first is the characteristics of above ground 'secondary suspended river', the second is the 'dual-function' of the floodplain, i. e. the important area for flood release, flood detention, sediment deposition and also the homeland of people living in the floodplain; and the third is the prominent contradiction between floodplain economic and social development and river regulation. The main research and practice of the Lower Yellow River channel and floodplain treatment are reviewed, which include the changing trend of incoming discharge and sediment load of the Lower Yellow River in the future, keeping a broad flood plain with solid embankment or keeping river channel with solid embankment, the existence or abolishment of production levee, the floodplain management mode, the treatment of secondary suspended river, the floodplain safety improvement, river channel reconstruction and so on. The practice and effect of sediment trapping by reservoirs, water and sediment regulation governance of Secondary Suspended River and safety construction of floodplain which were carried out in the Yellow River in recent years were studied. The understanding of governance of the Lower Yellow River channel and floodplain and problems that should be further studied in the next stage is put forward
