Plant landscapes infl uence human health through multi-sensory interactions involving visual, olfactory, and other senses. In recent years, research on the relationship between the characteristics of plant landscapes perceived through vision and smell and human health has gradually increased, but there is still a lack of organization and integration. This study focuses on the impact of plant landscape characteristics (such as color, shape, and fl oral scent) on physical and mental health through visual and olfactory perception, particularly their eff ects on physiological regulation, emotional improvement, and social interaction. Based on major Chinese and English databases, representative literature on the relationship between plant landscape characteristics and health benefi ts from the past decade was identifi ed and analyzed, resulting in the selection of 59 studies that met the inclusion criteria. The analysis of the included literature covered the quantity of research, disciplinary areas, and main hotspots, and summarized fi ndings across four aspects: research content, action mechanisms, perception pathways, and methods. The results indicate that: (1) Over the past decade, international research has seen signifi cant growth from 2015 to 2020, while domestic research on related topics gained attention around 2016. International studies are mainly concentrated in ecology and environmen-tal science, while domestic studies predominantly focus on architectural science and engineering. In recent years, international scholars have shifted from the qualitative description of single sensory perceptions to the analysis of multi-sensory stimulation mechanisms. Domestic scholars remain focused on studying the eff ects of perception, with an emphasis on visual perception and subjective feelings, and quantitative research is relatively scarce. (2) Current research primarily focuses on the infl uence of the overall color or shape of green plants, while the visual appearance diff erences of foliage plants and ornamental trunks or tree forms have not been suffi ciently explored, particularly regarding their impact on the cardiovascular system, mental state, and social activities. This leads to a lack of nuanced, diversifi ed understanding of plant landscape characteristics through visual and olfactory perception, failing to provide more specifi c, diverse guidance on plant arrangement for landscape design. Current research mainly employs landscape recognition technology, but it still lacks precision, automation, and dynamism. Future research needs to integrate multi-sensory perspectives to construct an indicator system for plant landscape characteristics and identify their multi-dimensional features to further enhance the quality of urban plant landscapes.
