As a new type of cultural heritage, campus heritage should be established as a scientific and comprehensive protection system. How to build a detailed and comprehensive heritage protection system based on current research is a complex issue in current research and practice. Taking the Shipai campus heritage of the former National Sun Yat-sen University campus as an example, based on qualitative analysis of the current campus heritage resources, the Analytic Hierarchy Process is used to construct a heritage value evaluation system and to determine the evaluation factors and their weights. A questionnaire is designed to score different existing heritage units on the campus, and the fully arranged polygon graphical indicator method is used to visualize the value evaluation results of different landscape units. Comparing the resource values of different heritage units, the results indicate that: (1) To build a comprehensive and detailed campus heritage protection system that spans administrative boundaries, the protection of campus heritage should follow the principle of integrity; (2) Quantitative methods such as the fully arranged polygon graphical indicator method are more conducive to the scientific and objective evaluation of the value of campus heritage, and can deepen the understanding of the correlation between various heritage elements and the overall protection of campus heritage; (3) Campus heritage should be attached importance to the hierarchical and continuous protection of history. The research method will provide a theoretical and methodological basis for constructing a value evaluation and protection system like campus heritage.
