Wuyi Mountain in China is listed on the World Natural and Cultural Heritage List. With the vigorous development of urban cultural tourism, the sustainable development of heritage sites has become the focus of academic and industry circles, among which the rational use and scientific planning of natural resources have become increasingly prominent. In this context, in-depth research on resource development and protection strategies in the Wuyishan area has important practical significance and theoretical value. Therefore, this paper presents a case study of the tourist tea garden landscape design practice at the Wuyistar Chinese Tea Garden, located in Wuyishan City. This paper underscores the significance of incorporating the site’s existing natural environment resources, particularly its plant resources, into the tea garden landscape design, while adhering to principles within the framework of world heritage. The research method includes extensive field surveys combined with GIS analysis and biodiversity surveys, covering the topography and slope of the tea plantation, current natural resources, statistics on the number of tourists after completion, and the related benefits of local enterprises. These planning concepts are realized through a series of infrastructure measures, which are divided into four angles: restoring mountains and rivers, rereading cultural context, sorting out style and appearance, and improving functions. The design practice is carried out in different areas. Simultaneously, the creation of a distinctive tourist destination enables tourists to fully engage with nature and tea culture, while simultaneously fostering the growth of cultural tourism in world heritage sites. This study proposes a planning practice case, which provides a framework and ideas for designing tea gardens. From the aspects of resource protection and utilization, cultural inheritance and display, and tourism service improvement, it provides a model and method that can be used as a reference for the landscape design and planning of similar tea gardens, which will help promote the healthy development of the Chinese tea culture tourism industry. It also provides useful practical experience for the protection and development of world heritage sites.
