摘　　要：以张北县草原天路为对象,采用地理信息系统和AHP层次分析法进行研究,对其路侧5 km范围内的生态敏感性进行了单因子分析和综合分析。结果表明,草原天路路域各级生态敏感性面积比较接近,位置分布存在明显特点:不敏感区占比11.38%,面积为75.45 km^(2),其余四级敏感区面积相似,占比均在22%左右,其中中敏感区所占面积最大,为150.17 km^(2),占比22.65%,中低敏感区域主要集中在西段北侧,高敏感及以上主要集中在公路东段。通过量化分析得出的各级敏感区分布特点和占比结果,可为草原天路的旅游建设规划和生态保护提供依据。This study focuses on the grassland road in Zhangbei County,employing ageospatial approach and the Analytic Hierarchy Process(AHP)for a comprehensive analysis of ecological sensitivity 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-sensitive area covers 75.45km^(2),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 150.17km^(2),or 22.65%.The moderately 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 valuable insights for informed decision-making in the planning and sustainable development of tourism services along grassland roads.
