The "Xuannan culture", as an important part of Beijing history and culture, which formed in the Xuannan district of Beijing in the Qing Dynasty, was a kind of "hierarchic culture" with celebrities and scholars. From the "field" view, Xuannan district was a field of hierarchic culture. By extracting POI of the three kinds of core architectural culture landscape elements: 327 temples, 211 celebrity residences, 535 guild halls, which mainly bore the hierarchic culture of Xuannan district, this study analyzed the spatial distribution of the three types of "micro field" respectively and as a whole, as well as the relation and aggregation between two. Thus, it proactively explored the existence, scope and spatial characteristics of the core area of hierarchic culture of Xuannan as "sub-field", and the aggregation of the elements and the internal causes of its formation. The conclusions mainly include: (1) By using the average nearest neighbor calculation and spatial density analysis, we found that the core area of hierarchic culture was the "two-kidney" shaped area in the central and north-central part of the western outer city, which was close to the secular culture area, and its range was stable and had no absolute clear boundary. The locations of the core hierarchic and the secular culture areas reflected the relation of the two cultures: exclusive and dependent, infiltrative and complementary. (2) By using the overlapping analysis of core density, OD distance and the bivariate spatial correlation analysis, we concluded that the spatial characteristic of the core area of hierarchic culture was "chain type" of "three elements, and two gatherings". The first gathering was the relationship between the temples and the celebrity residences. The second was that between the celebrity residences and the guild halls. Through two cluster analyses, it is found that the hierarchical spatial structure of "center -- transition center" was formed in the core area of Xuannan hierarchic culture. (3) It is quantitatively verified that "the feeling of hometown" was the driving force of celebrity residences and guild halls gathering. Under the strategic positioning of Beijing "cultural center", this article lays a historical research foundation for the proposal of Xuannan culture protection and inheritance strategy. In the history and culture research field, this research has innovation and reference significance in perspective and method.
