基于GIS与层次分析法的景观道路选线优化设计——以济南龙洞风景区为例
Optimization Design of Landscape Road Route Selection Based on GIS and Analytic Hierarchy Process—Taking Jinan Longdong Scenic Area as an Example

在风景区规划中，为对风景区的相关内容进行有针对性的筛查，可以通过GIS和层次分析法，对风景区建立评价体系，通过现场调研、局部踏查等方法为筛选提供阈值。本文通过对龙洞风景区的实地调研，对场地的问题进行总结，发现场地内部交通过于简易，同时又对前来登山的游客产生一定的风险，所以计划对龙洞风景区的景观道路选线优化设计，提取高程、坡度、土地利用类型、视觉敏感度这四个因子，通过层次分析法进行加权赋值，分别为0.40、0.34、0.10、0.16，叠加得到最低成本，结合GIS的成本连通性工具进行游步道体系的架构，节省了选线设计成本，提高了选线的可行性，可以为其他具有复杂地形的山岳型风景名胜区的路线规划提供科学可靠的依据。
In landscape planning, to conduct targeted screening of scenic areas, you can establish an evaluation system using GIS and the Analytic Hierarchy Process (AHP). By combining on-site surveys and local investigations, you can set thresholds for selection. In this study, we conducted field research in the Longdong Scenic Area, summarizing site issues. We found that internal traffic within the site was too simple and posed risks for mountain climbers. Therefore, we planned to optimize the design of landscape road routes in the Longdong Scenic Area. We extracted four factors: elevation, slope, land use type, and visual sensitivity. Using AHP, we assigned weights of 0.40, 0.34, 0.10, and 0.16, respectively. By overlaying these factors, we obtained the minimum cost. Combining GIS cost connectivity tools, we established a trail system, reducing design costs and enhancing route feasibility. This approach can provide a scientifically reliable basis for planning routes in other mountainous scenic areas with complex terrain.
