【摘要】 通过构建一套街景指标评分系统与空间权重划分方法研究和评估大理古城街景的空间质量，为古城的保护和更新提供科学依据。采用层次分析法（AHP）和熵权法相结合的综合赋权法，对大理古城的街景指标进行量化分析。通过对街景图像的语义分割和专家评分法，建立一个精细化的街景评价体系，并提出相应的优化策略。研究不仅为大理古城街景的优化提供了理论和方法论支持，也为其他古城的保护和发展开辟了新路径。更多还原

【Abstract】 A spatial weight division method based on streetscape indicators was constructed to study and evaluate the spatial quality of the streetscape in Dali Ancient City, thereby providing a scientific basis for the protection and renewal of the ancient city. The comprehensive weighting method, which combines the analytic hierarchy process(AHP) and the entropy weight method, was adopted to conduct a quantitative analysis of the streetscape indicators of Dali Ancient City. Through the semantic segmentation of streetscape images and the expert scoring method, a refined streetscape evaluation system was established, and corresponding optimization strategies were proposed. The study not only offers theoretical and methodological support for the optimization of Dali Ancient City’s streetscape but also opens new pathways for the protection and development of other ancient cities.更多还原
