摘要 The buffer zone of a World Natural Heritage Site constitutes a critical element of the heritage site protection system. It functions not only as an ecological security barrier but also significantly influences the visual integrity and aesthetic value of the core area’s landscape. Given the rapid development of transportation infrastructure, particularly the growing number of high-speed railways traversing ecologically sensitive regions, the scientific assessment of their impact on the landscape environment of heritage sites has emerged as a pivotal concern in heritage conservation and regional development. This study focused on the section of the Guiyang-Nanning High-Speed Railway that traverses the buffer zone of the Libo World Natural Heritage Site in Guizhou Province. Beginning with five primary indicators, including natural landscape and aesthetic value, geological geomorphology and Earth history value, biodiversity value, integrity and protection management, and impact on ecological environment, a visual landscape impact assessment system for high-speed railways was developed based on the analytic hierarchy process (AHP) and the fuzzy comprehensive evaluation method (FCE). Through expert scoring, hierarchical weight calculation, and fuzzy membership degree analysis, a comprehensive assessment was conducted on the landscape ecological quality, visual coordination, and aesthetic perception within the buffer zone following the construction of high-speed railways. The findings indicate that the construction of the Guiyang-Nanning High-Speed Railway generally harmonizes well with the landscape environment of the heritage site. The level of visual disturbance remains within an acceptable range and has not significantly damaged the overall aesthetic value or authenticity of the heritage site. Although the integrity of the landscape in certain local areas has experienced a slight decline due to the exposure of bridge and slope structures, the adverse effects have been effectively mitigated through engineering interventions such as vegetation restoration and color coordination. This study innovatively integrates the AHP with fuzzy mathematics methods to achieve a comprehensive evaluation that combines both qualitative and quantitative approaches. This integration provides a scientifically grounded analytical path and a practical technical framework for assessing the visual impact of linear infrastructure projects, such as high-speed railways, within the buffer zones of World Heritage Sites. The findings offer valuable insights for the protection of landscapes and the sustainable development of infrastructure in heritage sites.
