Abstract

ABSTRACT: Biocultural diversity is an important result and outstanding representation of human-land relationship. This study established a novel framework for evaluating the coupling mechanism of biocultural diversity beyond the nature-culture dualism. Taking the Beichuan-River-Source National Nature Reserve (BRSNNR) as an example, combined with regional characteristics, Coupling Coordination Degree Model (CCDM) and Canonical Correlation Analysis (CCA) were used to explore the correlation mechanism between natural systems and cultural systems in protected areas. The research results indicated that BRSNNR had five types of landscape character areas with outstanding natural and cultural characteristics; the spatial distribution of biodiversity and cultural diversity was highly overlapping, forming a 'high-medium-low' three-level biocultural diversity area. Analysis demonstrated that positive or negative feedback patterns between natural and cultural systems contributed to the formation of representations of biocultural diversity. Altitude, animals, and traffic conditions are important drivers for the biological and cultural diversity in protected areas. At the same time, residents' emotions and behaviors have a direct impact on the formation of biocultural diversity. The research suggests that the priority protection areas and functional divisions of protected areas should be delineated according to the evaluation results of biocultural diversity, and thresholds should be calculated and set for the constraints. This method is conducive to the improvement of the system's ability to deal with risks and the formation of the action mechanism of 'factor interaction-system interaction-biocultural diversity representation' in protected areas.
