Assessment and driving mechanisms of hidden land degradation in religious tourism
摘要
Mountainous scenic areas serve as core venues for religious tourism and festive activities, characterized by high ecosystem vulnerability and sensitivity to human disturbance. Mount Sanqing in China, a Taoist sacred site and representative mid-subtropical red soil ecosystem, faces threats of hidden land degradation associated with religious tourism. This study selected nine core indicators and constructed an assessment framework for hidden degradation using the Projected Pathway Analysis (PPA) and Geographically Weighted Regression (GWR) to analyze spatial heterogeneity of driving factors. Covering the core Taoist tourism area of Mount Sanqing, the research integrated data from over 210 red soil samples, 105 vegetation plots, and 450 questionnaires. Findings reveal that the degree of hidden land degradation exhibits a gradient variation with the intensity of religious activities and the frequency of human disturbance. The physical properties of red soil show the strongest association with degradation, with erosion further exacerbated during the plum rain season. Driving factors show pronounced spatial differentiation: community economic dependence appears to be the primary correlate in low-altitude areas, while tourism pressure dominates the spatial pattern in high-altitude zones.
