River system patterns significantly influence the location and layout of human settlements. The location of a city is typically in close proximity to a major river for the purpose of water supply, but a certain separation distance is maintained to minimize the risk associated with flooding. Therefore, there is usually a direct relationship between the city network and river systems in a region. The evolution of city distribution from 221 B.C. to 1911 A.D. in the North China Plain is spatially analyzed using historical data on cities and rivers to investigate the relationship between city network and geographic setting, especially with respect to the Yellow River and related river systems. The results indicate that the mean center of the city network initially moved southeastward and then northeastward, which matches the southward migration of the Yellow River and subsequent construction of the north-south orientated canal. Equilibrium and re-equilibrium mechanisms are conceptualized to describe the characteristics of such coupled city-river systems that are involved in a co-evolutionary process and shaped each other. These past interrelationships may provide guidance on the selection of the location of future cities and water conservancy engineering and may be helpful in more efficaciously addressing the relationship between cities and their water supplies. |
