Quantitative evaluation of plants on top surface of the Great Wall in Dazhuangke using the analytical hierarchy process

A quantitative evaluation of plant species on the Dazhuangke section of the Great Wall reveals that 45 species or categories significantly impact the structure, with 'Disruptive Effects' being the most critical factor. Using the Analytic Hierarchy Process and expert Delphi method, researchers identified 13 key indices across three constraint layers to assess plant-induced damage. The study found that 'Impact on the Near Side Wall' is the highest-weighted element in the evaluation model, guiding preservation recommendations categorized into Grade I ('Preservation'), Grade II ('Partial Preservation'), and Grade III ('Removal'). This approach provides a scientific basis for balancing heritage protection with plant management strategies.
