位于北京东城区南池子大街东侧，毗邻紫禁城的普度寺，曾是明清时期皇家扶持的重要佛教寺院。本文以普度寺慈济殿抱厦东南角的转轮经藏为研究对象 ：一方面，将其置于整座寺院的空间语境中，借助民国来华学者的文献记述与遗留老照片，钩沉该转轮经藏的内部构造与外部装饰 ；另一方面，通过对转轮经藏大理石压栏石刻图像的辨识与考证，并将其与雍和宫铜铸须弥山进行比对，发现普度寺转轮经藏是以立体构造的方式模仿佛教宇宙世界的缩微模型。

Located east of Nanchizi Street in Dongcheng District, Beijing, adjacent to the Forbidden City, Pudu Temple is an important Buddhist temple supported by the imperial family during the Ming and Qing Dynasties. This paper takes the revolving sutra repository at the southeast corner of the auxiliary hall of Ciji Hall in Pudu Temple as the research object: on the one hand, by placing it in the spatial context of the entire temple, and analysing the documentary accounts by visiting scholars during the Republican era and surviving historical photographs, we can reconstruct the internal structure and exterior decoration of this revolving sutra repository; on the other hand, through the identification and textual research of the marble balustrade of the revolving sutra repository, and by comparing it with the bronze Mount Sumeru at Yonghe Temple, it is found that the revolving sutra repository at Pudu Temple is a miniature model that replicates the Buddhist cosmic world through three-dimensional structure.
