Spatio-temporal Evolution of the Rural Regional System and Its Evolution Mechanism in Huang-Huai-Hai Area of China

The problem of rural development arises from the evolution of rural regional system. It is urgent to deepen the research on the evolution process and mechanism of rural regional system. However, there are relatively few studies on rural development from the perspective of the evolution process, driving mechanism and evolution mechanism of rural regional system. Therefore, this study took Huang-Huai-Hai Area for example, started with the systematicness of the rural regional system, the spatio-temporal pattern and driving mechanism of rural regional system evolution, and further summarized and refined the evolution mechanism of the rural regional system. The methods of spatial pattern analysis, gray correlation degree and geographical detection were adopted. The results showed that the problems in rural areas were often dominated by one factor and produced by the joint action of many factors. Factors such as county urbanization, county economy, county public service, agricultural mechanization, surrounding cities and convenient transportation will affect the evolution of rural regional systems. Based on the evolution of the elements in the rural regional system, the evolution types of rural regional system can be divided into decline type, equilibrium type and growth type. This study can provide a reference for understanding the process of rural rise and fall and can also guide rural revitalization and rural sustainable development.
