Response Pathways and Health Benefits of Biodiversity Perception Based on Audio-Visual Collaboration

Biodiversity is a key evaluation criterion of natural environments, and its positive effects on human health are well-documented. Some recent studies suggest that biodiversity perception (BP) may play a crucial role in explaining the relationship between biodiversity and health. This study introduces the “Environment-Psychology-Perception-Benefit” theoretical framework, grounded in audio-visual Integration, to investigate how BP influences both physical and mental health. A total of 380 participants were recruited for this research. Structural equation modeling (SEM) is employed to examine how nature relatedness, nature attitude, and nature cognition impact BP through psychological identification (PI). Pearson’s correlation analysis is also conducted to explore the relationships between BP, actual biodiversity, and environmental perception factors. Additionally, the recovery benefits of different levels of BP on physiological indices were evaluated through controlled experimental conditions. The results show that nature attitude is significantly positively correlated with BP, and nature relatedness positively influences BP via PI. BP notably enhances psychological recovery, attention, and stress reduction. Medium BP environments provide the highest levels of relaxation and recovery, while high BP environments significantly enhance attention restoration. This study offers an in-depth exploration of the mechanisms and benefits of BP, advancing the theoretical understanding of BP and offering foundational support for biodiversity conservation, utilization, and nature-based therapeutic practices.
