STUDY ON THE HISTORICAL CHANGES IN THE CENTRAL AXIS OF BEIJING BASED ON MODERN TECHNOLOGY

Abstract. With the acceleration of urbanization, the Chinese government has placed increasing importance on the preservation of historical and cultural sites. Recently, the Beijing municipal government has been working on the World Heritage application for the Beijing Central Axis for several years and has set a clear goal to formally apply for World Heritage status before 2025. Currently, the project has entered the final sprint stage (Zhang Yongjun, 2018(12):105-107).The Beijing Central Axis, as an important carrier of natural and cultural heritage, embodies a unique cultural heritage. As "Beijing's unique and magnificent order," the Central Axis is not just a single line but a corridor. However, during the preparation for the World Heritage application, there have been different understandings of the concept of the Central Axis, and the selection of heritage sites has not been comprehensive and systematic. Therefore, in studying the issues related to the Central Axis, utilizing POI data to conduct kernel density analysis and linear regression analysis on the cultural landmarks within Beijing can help infer the location of the Central Axis in different periods. By employing spatial analysis methods using ArcGIS, a systematic study of the characteristics of the Beijing Central Axis can be conducted, summarizing its distribution and spatial form characteristics across different dynasties. This research can provide valuable reference for future in-depth studies, conservation and utilization efforts, and the World Heritage application of the Central Axis.
