Spatiotemporal Behavior and Hotspot Analysis of Tourists in Yuntai Mountain Scenic Area Based on Multi-source Data

Selecting Yuntai Mountain Scenic Area as the case study, this research integrates multi-source heterogeneous data, including social media texts and tourist GNSS trajectories. By comprehensively applying the Analytic Hierarchy Process (AHP) and Direction-Constrained DBSCAN (DC-DBSCAN), it analyzes the characteristics of tourists' online attention and physical spatiotemporal behaviors, constructing a virtual-real coupling response mechanism for the scenic area. The results show: (1) The online attention of Yuntai Mountain Scenic Area exhibits an alternating "stable-pulse" fluctuation pattern, significantly influenced by statutory holidays, with tourists' focus concentrated on core attractions and considerable negative emotional feedback regarding physical exertion. (2) The physical flow of tourists demonstrates a temporal rhythm of "early entry, late exit, and single-peak aggregation." Spatially, a core skeleton road network primarily consisting of Fenghuang Ridge and Hongshi Gorge is formed. The duration of stay presents a bimodal clustering characteristic of short-term check-ins and in-depth experiences. (3) There is a significant spatiotemporal divergence between online attention and offline physical flow. Temporally, the rise in online heat precedes the peak of physical tourist flow by 1-2 weeks; spatially, Hongshi Gorge shows a virtual-real balance, Zhuyu Peak exhibits online overheating, while experiential attractions like Fenghuang Ridge and Xiaozhai Valley present significant offline overheating.
