A Review of Fengshui Forests: Ecological Functions, Humanistic Values, and Potential Applications to Enhance Biodiversity in Urban Green Landscapes and Achieve Sustainable Development Goals

Sustainable urban development increasingly aligns with the Sustainable Development Goals (SDGs), highlighting the importance of integrating local cultural landscapes into city planning. One compelling example is the concept of fengshui forests in China, which are deeply rooted in traditional beliefs associated with prosperity for local communities. This study explores how fengshui forests can inform urban landscape design, particularly in the context of biodiversity conservation. A comprehensive literature review was conducted, examining studies on the ecological functions and cultural significance of fengshui forests. This analysis included research articles, case studies, and ecological assessments, revealing that fengshui forests provide essential ecosystem services—such as preserving biodiversity, regulating microclimates, and sequestering carbon—while also offering unique cultural insights, economic resources, and tourism potential. Recognizing the critical role of plant selection and combination in urban landscape design, we compiled a database of 1,196 recorded plant species from fengshui forests, detailing their physiological traits, geographical distribution, and social values. By employing diverse plant pairing principles, urban landscape designers can select suitable species to create green spaces that support a well-functioning food web and ecosystem, ultimately fostering biodiversity conservation. By harnessing both the ecological functions and cultural values of fengshui forests, this research highlights their potential to enhance urban eco-landscape design, promote eco-tourism, and aid in the preservation of local species. These forests, with their traditional roots and ecological significance, hold promise for advancing ecological civilization through effective biodiversity conservation and sustainable urban planning.
