Abstract: With the Wanglang zone of the Giant Panda National Park as a case study, this study constructs a spatial suitability evaluation framework for the outdoor interpretation system of mountainous canyon-type national parks. This provides a scientific evaluation methodology for spatial planning that strictly adheres to ecological conservation principles. The study selects evaluation factors from three dimensions: ecological sensitivity, interpretation resource endowment, and facility support, establishing an evaluation system. The CRITIC objective weighting method is employed to determine indicator weights. Combined with spatial autocorrelation analysis and hot-spot/cold-spot analysis, the spatial distribution patterns of suitability are identified. The findings systematically demonstrate the spatial distribution characteristics and functional implications of suitability evaluation for mountainous canyon-type national parks. The core findings are summarized as follows: (1) Spatial suitability exhibits a highly significant clustering distribution pattern, with a global Moran′s I value of 0.847. The boundaries between high-suitability and low-suitability areas are distinct and well-demarcated. (2) High-suitability areas cover a total area of 10.4km², accounting for only 3.2% of the total study area. They are concentrated in the central Y-shaped canyon corridor, forming a hot-spot distribution belt along the Muyangchang-Zhugencha-Dawodang corridor. This clustered distribution is closely related to the original terrain, existing facilities, and interpretation resources. Although parts of flagship species habitats are included, utilizing these "existing disturbance zones" for interpretation activities remains the optimal choice and can serve as priority zones for optimizing nature education and interpretation. (3) Cross-analysis of spatial suitability and the national park′s functional zoning yielded key conclusions: Within the general control zone, high-suitability and relatively high-suitability areas account for 26.1% and 26.55% respectively, leaving 47.35% of the zone unsuitable for large-scale visitor activities. The analysis identifies and excludes highly sensitive habitats like primary forests within the general control zone, thereby minimizing potential disturbance to sensitive ecosystems. The core protection zone still contains 1.50% high-suitability area, which can be cautiously utilized for providing nature education and outdoor interpretation service under strict supervision. These results indicate that while the national park′s functional zoning provides a macro-level regulatory framework for the spatial planning of the outdoor interpretation system, systematic scientific evaluation is still necessary to refine the planning and implementation process. (4) Cold-spot zones constitute 20.8% of the total study area, widely distributed across high-altitude, high-slope, and high ecological sensitivity ridgelines, showing significant overlap with the core protection zone of the national park. (5) The evaluation results validate the scientific rationale behind the "multi-point feathered" layout of the existing outdoor interpretation trail system. All trails and most interpretation points are located within high-suitability areas and the hot-spot corridor. This study establishes a scientific evaluation method, and provides evidence-based decision support for optimizing the spatial planning of outdoor interpretation systems in national parks. It also proposes a transferable spatial suitability evaluation scheme applicable to other mountainous canyon-type national parks and protected zones, supporting the goal of balancing conservation and sustainable use.
