Abstract:The rooftop garden, as a crucial component of the campus environment, provides a unique space for faculty and students to learn and interact, playing a pivotal role in improving the campus environment and regulating the emotions of the academic community. This study uses the rooftop garden of Tongji University's Yunchou Building as the research object.Evaluation factors were derived from a combination of questionnaire surveys and expert assessments. Using the Scenic Beauty Estimation (SBE) method, the Balanced Incomplete Block design-Law of Comparative Judgment (BIB-LCJ) method, and the Semantic Differential (SD) method, the scenic beauty of seven different themed garden plots and two sunflower control fields was studied in depth. The results reveal that the Leisure Garden scored high in all three methods, and the Wild Garden performed well in the scenic beauty score of the SD method, while the two sunflower fields scored relatively low in all three evaluation methods. To further enhance the scenic beauty of the rooftop garden's plant landscapes, it is recommended to focus more on plant colours and planting structures, increasing the diversity of plants, and the quantity of flowering and aromatic plants in the design. In addition, the study found that the SBE method demonstrates good applicability in the evaluation of small-scale plant landscapes.
