Exploration on the coordination mode of urban and rural areas in Jianli City under the perspective of GIS

In the process of sustainable and rapid development of regional urbanization and industrialization, urban and rural functional areas, as the agglomeration functional areas and organizational system bearing the main regional production factors, play a vital role in the overall development of urban and rural areas. However, at present, in areas with relatively backward economic development, the urbanization rate is low, the connection between towns is not close enough, the agglomeration economic benefits are low, and the urban and rural functional areas have not been formed or unreasonable, which seriously restricts the process of urban-rural integration and the improvement of overall competitiveness. Jianli city is a typical agricultural city in Jianghan Plain. With the promotion of industrialization and urbanization, the city urgently needs to integrate regional natural, economic, cultural and other resources, optimize the urban and rural spatial pattern, and realize the overall development of regional urban and rural economy and society. Taking Jianli city as an example, this paper uses the combination of qualitative and quantitative methods. First, it discusses the spatial agglomeration and spatial correlation characteristics of natural, social and economic resources based on G IS grid analysis. Secondly, the hierarchical analysis method is used to identify the spatial echelon distribution pattern of resource elements, and to preliminarily divide the urban and rural spatial functional areas. Then, the township gravity model is constructed, the preliminarily designated urban and rural areas are revised, and the spatial development mode of “point-line-surface” area coordination is put forward. Finally, based on the overall planning of urban and rural areas, the idea of multi-township merger planning is put forward to realize the balanced allocation and flow of urban and rural elements.
