Evaluation for the Development Potential of Rural Recreational Resources Surrounding Megacities: A Case Study of Zhengzhou

Under the requirements of ecological civilization and rural revitalization strategies in China, studying and evaluating the development potential of rural recreational resources surrounding the urban areas of megacities is of great significance for promoting the integrated development of urban and rural areas. Based on the collection and processing of multi-source datasets, this paper proposes corresponding evaluation methods for the development potential of three types of rural recreational resources (nature-historical culture-village). It combines AHP-entropy weight combination weighting, GIS spatial analysis, and Graphab network connectivity analysis to explore and evaluate the potential of rural recreational resources within the Zhengzhou urban area, which is in Central China. It quantifies the contribution degree and development priority of potential points to the overall recreational network. The results show that the recreational resources in rural areas are abundant and have great development potential. High potential points of the natural category are concentrated in the western shallow mountainous and hilly areas, with convenient transportation and a high green coverage rate, suitable for developing as suburban forest parks. High-potential points of historical sites are close to the urban area, and should be integrated and connected with the urban leisure corridors, suitable for developing as suburban cultural parks. High-potential points of villages are suitable for creating composite stations (homestay, study, folk customs) and developing into key nodes of the recreational network. Potential points with high contribution to the overall recreational network should be prioritized for development. In the future, the optimization and development of rural recreational resources can be achieved through four paths of overall planning, key promotion, brand driving, and network collaboration.
