As urbanization construction gradually enters the stage of stock enhancement and renewal, systematic analysis of the relationship between urban and rural green space development and plantscape research can effectively promote the sustainable development of human habitat and provide reference direction for subsequent research. The China Knowledge Network (CNKI) database was the data source. The number of articles was visualized and analyzed using the bibliometric tool VOSviewer, research institutions, Keywords, and other information of the 393 pieces of related literature on plantscape research from 2000 to 2023, and the results revealed that: (1) The plantscape research, in general, shows a trend of increasing and then decreasing, and the primary research involves the greening of the landscape with a variety of benefits assessment. (2) Many journal institutions publish related research papers, but the correlation between them could be more robust, and the related articles are mainly published in horticultural and agricultural journals. (3) The research mainly focuses on the themes of benefit assessment of planted landscapes, application of cross-disciplinary theories, excavation of the value of historical resources, and evaluation and reform of the landscape book courses; public green space, classical gardens, and textbook courses are the objects that have a high degree of attention in this research field. (4) The research methodology develops from survey statistics to mathematical model index analysis, the object experiences the transformation of a green landscape-user-human landscape mutual system, and the core of the research is shifted from plant configuration and community effect to the field of ecological civilization. Showing the trend of cross-integration of multiple perspectives and disciplines, the research is oriented to deepen from solving the problem of plant design elements to the perspective of analyzing the benefits of green space plant landscape. Based on the above analysis, it is concluded that the research strategy of strengthening the depth of multi-scale landscape research, improving the transformation efficiency of plant resource introduction, and deepening the integration of “single-complex” multi-knowledge theories should be proposed as the focus of future research.
