Research on the Spatiotemporal Distribution and Cultural Tourism Strategy of Modern Educational Architectural Heritage in Nanjing

The rebirth of educational architectural heritage plays an important role in the urban tourism economy, and studying the integration of educational heritage and tourism is of great significance and value. This article selects the educational heritage in Nanjing, China, from 1840 to 1952 as its research object to explore the integration and sustainable development relationship between heritage utilization and tourism. This article adopts a research method that combines qualitative and quantitative methods. First, it collects historical data and conducts on-site surveys to obtain information on 117 important educational heritage sites in Nanjing. Then, it uses ArcGIS technology to quantitatively analyze the evolution rules of modern educational buildings in Nanjing and the spatiotemporal distribution characteristics of the heritage. Finally, a cultural tourism strategy is proposed based on heritage characteristics and government policies. The research results reveal the interdependence and sustainable development relationship between the protection and utilization of educational heritage and tourism: according to the distribution characteristics of the heritage in the urban space, the "educational heritage tourism path" of the ancient city is constructed, which can promote the development of urban tourism. Subsequently, the economic value created by tourism is used to "feed back" heritage protection. This research result provides reference for educational heritage tourism in other cities in China and around the world.
