Environmental perception is a key indicator for evaluating green space preference and satisfaction. The shift in urban green space research towards emphasizing human benefits over functionality has caused a gradual increase in the number of articles on green space perception in recent years. Studying the relationship between the vegetation landscape (a fundamental aspect of urban green spaces) and subjective perceptual dimensions have become a pivotal research topic. This paper delves into the correlations and influencing relationships between these two dimensions with the main focus being on vegetation landscape indicators and subjective perception. The perceived green benefits were categorized into four main groups in the 80 articles reviewed: perceived safety, visual aesthetics, restoration benefits, and preferences. In this study, green indicators were also defined and categorized. The results indicated that the guiding indicators had a higher frequency and that species diversity improved the perceived benefits in all aspects. Among the control indicators, plant color, plant height, and the vegetation composition structure received the most attention. Plant color accounted for the largest proportion of studies on perceived visual aesthetics. Vegetation characteristics related to perceived safety had a shared trait, and there was a lack of correlation studies between safety and aesthetics in perceptual dimensions. In the common methods for assessing human perception, a shift from subjective measurements to mixed measurements using emerging technologies is underway. As a pioneering scope review of how vegetation landscapes influence subjective human perceptions, this study has not only provided evidence of the perceived benefits of urban green spaces but also offers valuable insights and tools for future research and policymaking.
