屋顶花园作为校园环境的重要组成部分，为师生提供了独特的学习和交流场所，并在改善校园环境和调节师生情绪方面发挥了关键作用。以同济大学运筹楼屋顶花园为研究对象，通过问卷调查和专家评价法提取评价因子，分别运用美景度评价法、审美评判测量法和语义差异法，深入研究了 7 个不同主题的花园地块以及 2 块向日葵对照田的美景度。研究结果显示，悠然花园在 3 种方法中的评分均较高，野趣花园在语义差异法中的美景度评分方面表现出色，而 2 块向日葵田在 3种评价方法中的得分相对较低。为提升屋顶花园植物景观的美景度，建议在设计中多注重植物色彩和种植结构，增加植物的多样性，多种植开花植物以及芳香植物。此外，研究发现，美景度评价法在小尺度绿地植物景观评价中具有较好的适用性。

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.
