China is a mountainous country; to alleviate the problem of land shortage in the process of urban construction and meet the demand of urban residents for green space, the use of natural mountains to build urban parks is a significant breakthrough to solve this problem. Furthermore, in order to better optimize the landscape space environment of urban mountain parks and meet the public’s higher demand for outdoor activity space. In this paper, CiteSpace software was used to analyze domestic research on urban mountain parks in the past 20 years. Based on the publication stage, research hotspots and research topics, the development context, research hotspots, and future development trends of related research in this field were summarized. Focusing on the three research topics of urban mountain park planning layout and design, urban mountain park post-use evaluation, and urban mountain park landscape space research and analyzing the key literatureto provide reference for the future urban mountain park planning layout and landscape optimization, as well as provide a reference suggestion for the next stage of research topics.
