This paper designed the village platform reconstruction plan according to the flood control standard of resisting the once-in-twenty-year flood. Based on the water and sediment data, land use type data and terrain data of floods of different return periods in the lower Yellow River, Delft3D software was used to establish a two-dimensional mathematical model of water and sediment, and the flood evolution of the Huayuankou-Aishan section in the lower Yellow River under the current plan of the village platform and the reconstruction plan of the village platform were simulated and calculated respectively. The results show that under the two schemes, with the increase of flood magnitude, the submerged area of floodplain and non-residential land is gradually increased. Compared with the current village platform plan, under the village platform reconstruction plan, the submerged area of floodplain and residential land is reduced, and the submerged area of non-residential land slightly increases, but the submerged water depth of floodplain and non-residential land is gradually increased, and the proportion of the area in which the submerged water depth of the residential areas is reduced is more than 95%. The village platform reconstruction plan can reduce the submerged area and submerged water depth of the residential area in the study area, and play a role in protecting the residential area.

The Lower Yellow River floodplain is a flood detention and desilting area, at the same time it is also the homeland of floodplain residents. There are still 915.8 thousand residents lack of security for flood control. The people live in poverty. The unfavorable channel pattern in the Lower Yellow River makes the Yellow River's flood control situation still severe. Fully considering the national ecological development strategy in the new era and the economic and social development requirements along the Yellow River, the paper put forward 5 specific modes for ecological reconstruction management of the Lower Yellow River floodplain and the detailed ways to implement them. The effect of ecological management was evaluated from flood control, safety of residents in beach area, ecology and economy. The results show that the management has significant effects on economy, society and ecology. It is suggested that the state should accelerate the work of the ecological management.
