(3) In order to solve the problem of the contradiction between people and land in the lower reaches of the lower reaches of the Yellow River and to meet the requirements of flood control, the simulation of village relocation in the lower reaches of the Yellow River is studied and 3 relocation scenarios are set up. Under the situation of flood control security, the villages with the largest 5 villages and towns inundated in the lower reaches of the lower reaches of the Yellow River are selected as the relocation objects, and the villages and towns are relocated, Cross Township resettlement, near resettlement, centralized resettlement, and reclaim area reclaimed cultivated land and woodland; under the development priority situation, the village of 5 villages and towns with the lowest 5 per capita is selected as the relocation object, the village is mainly concentrated into the county town, the town, the trunk road, the tourist attractions and the park. As the object of relocation, the villages with the lowest ground area of the 5 villages and towns are mainly used in the same Township resettlement, cross Township resettlement, near resettlement, the minimum occupancy of arable land in the resettlement process and the reclaimed land reclaimed in the relocated area.
