In the 21st century, China’s research in rehabilitation landscapes has continued to increase, and research directions have differentiated. The article uses the document visualization analysis software CiteSpace to draw a knowledge map and analyze the literature related to China’s rehabilitation landscape from 2000 to 2020 included in the CNKI database, inspiring scholars to get the foundation of such its deficiencies, then to promote the in-depth research, the primary research status and hot topics of the rehabilitation landscape. The research results show that the research on China’s rehabilitation landscape mainly includes three themes: the role and evaluation of the rehabilitation landscape, the planning and design of the rehabilitation landscape space, the rehabilitation plant landscape design. Many academic cooperation teams have formed in the field. Still, there are relatively few cross-university and cross-disciplinary integrations for the rehabilitation landscape evaluation feedback and evidence-based design methods, which both used more to guide future planning and design. Meanwhile, the rehabilitative landscapes can genuinely play the function of rehabilitation. The research on rehabilitation gardens’ mechanism is also one of the hot spots that can be discovered in the future.
