Post Occupancy Evaluation (POE) is an evaluation method to provide feedback on the built environment .In order to objectively grasp the breadth and depth of POE research, research frontiers and research objects, this paper analyzed 620 documents included in CNKI through bibliometric methods. Combined with the number of documents, author cooperation network, keyword clustering, keyword timeline, keyword burst and specific document content, the paper sorted out the research context and evolutionary characteristics of POE in landscape architecture, research hotspots and frontiers, and provided suggestions for future development. The research shows that POE research in the domestic landscape architecture discipline can be divided into three development stages: a preliminary study of theory and method, multi-dimensional perspective exploration and practice, connotation expansion, and technical innovation. It is closely related to domestic social development needs and shows continuity and advancement in the research object, content, and method. The research hotspots focus on three aspects: the multi-dimensional evaluation of the built environment, the relationship between users and physical space, and the innovation of quantitative evaluation methods. By summarizing the current research, the paper looked forward to the future institutional cooperation, the improvement of the evaluation system and the application of scientific research methods, in order to improve the standardization of post-use evaluation of the built environment and promote the further development of POE research in landscape architecture.
