Ecological sensitivity analysis of tourist highway based on GIS——Taking the east line of Zhangbei grassland road as an example
This study focuses on the grassland road in Zhangbei County,employing a geospatial ap-proach and the Analytic Hierarchy Process(AHP)for a comprehensive analysis of ecological sensi-tivity within a 5-kilometer radius of the road.The findings reveal that ecological sensitivity areas exhibit a relatively uniform distribution across various sensitivity levels.Specifically,the non-sen-sitive area covers 75.45km2,constituting 11.38%of the total area,while the other four sensitivity levels are roughly equivalent,collectively accounting for approximately 22%.Among these,the moderately sensitive area is the most extensive,encompassing 150.17km2,or 22.65%.The moder-ately and low-sensitive areas predominate in the northern segment of the western section,while the highly sensitive and above areas are concentrated in the eastern section of the highway.This quantitative analysis elucidates the spatial distribution patterns of sensitivity levels,offering valua-ble insights for informed decision-making in the planning and sustainable development of tourism services along grassland roads.
