基于GIS的陕甘宁地区红色旅游气候舒适度评价 postprint

Abstract: Assessing climate comfort in the Shaanxi-Gansu-Ningxia region is crucial for developing red tourism resources and promoting ecological sustainability. Based on daily meteorological data from 1953 to 2020, including average temperature, wind speed, and relative humidity, this study employs a comprehensive climate comfort evaluation model, integrated with GIS spatial interpolation and comprehensive zoning methods, to systematically analyze the spatiotemporal distribution characteristics of climate comfort in the region. The results indicate that, temporally, the climate in the region is generally comfortable from May to September, whereas from December to February of the following year, it is predominantly characterized by discomfort. Spatially, northern Shaanxi exhibits relatively comfortable climatic conditions, while the southwestern Xihaigu region is less suitable in terms of climate comfort. Against the backdrop of global warming, the annual average number of comfortable days has shown an increasing trend, while the number of uncomfortable days has significantly decreased since 2000. Comprehensive zoning results indicate that southwestern and central high-altitude areas experience lower comfort levels, while other regions remain relatively favorable. Further analysis demonstrates that for every unit change in the climate comfort index, the red tourism visitor flow index correspondingly changes by 0.593%. Notably, Yan’an, due to its abundant red tourism resources and favorable climate conditions, exhibits a significantly higher attractiveness index compared to other regions. Moving forward, red tourism planning should be dynamically optimized to accommodate climate change and evolving tourist demands. This study provides a scientific reference for regional tourism development and the sustainable advancement of red tourism activities.
