Abstract:

In the changing history of the Yellow River, the third major diversion has led to a sudden northward migration, which radically changed the urban natural and human environment in the flood area and is an ideal research area of the human-earth coupling system. We used a combination of horizontal cross-sectional methods, mathematical statistics and GIS tools to explore the number, spatio-temporal variability characteristics and urban adaptations of the cities flooded by the Yellow River. The results show that: (1) The overflowing of the Yellow River during the seven river-flowing periods gave rise to 29 affected cities. (2) The affected cities were widely distributed in general, but relatively concentrated in the top of the alluvial fan formed by the bursting of the Yellow River, the low-lying Jizhong Plain and the confluence of the Yellow River and Yuhe River. (3) The cities flooded by the Yellow River mainly showed four types of urban adaptability: direct destruction, dismantling, relocation and reinforcement, in which the type of the relocation of floods is dominant, accounting for 45%. (4) The imperial court decision and city scale were important human factors affecting the spatial differentiation and urban adaptability in the sudden disaster environment of the Yellow River. The affected cities in the flooded areas are important models of local conservation significance and sustainable development evolution, which is recommended that they should be included in the national strategy of "Ecological Protection and High-quality Development of the Yellow River Basin" and as an important area for telling the story of the Yellow River.

Key words: Northern Song Dynasty, Yellow River, cities flooded by the Yellow River, urban adaptability
