摘　　要：利用GIS空间分析技术和综合评价法进行高速公路的路径规划,建立一种基于AHP-熵权法的公路选线模型,从而降低规划过程的复杂性。以河北沿海高速唐山段为研究对象,选取土地利用类型、坡度、坡向、水文、断层、土壤类型、GDP、旅游资源和生态敏感度九种地理指标评价因子,分别建立基于层次分析法和熵权法的高速公路选线方案决策模型,并结合两种方法建立综合评价模型生成最优路径与原路径进行对比。结果表明,结合两种评价方法生成的最优路径与原路径有较高拟合,基于AHP-熵权法的高速公路选线模型在对比有一定优势。GIS spatial analysis technology and comprehensive evaluation method are used for highway route planning,and a highway route selection model based on AHP-entropy weight method is established to reduce the complexity of planning process.Taking Tangshan section of Hebei coastal expressway as the research object,nine geographical index evaluation factors including land use type,slope,slope direction,hydrology,fault,soil type,GDP,tourism resources and ecological sensitivity were selected to establish the decision model of expressway route selection scheme based on AHP and entropy weight method respectively.Combined with the two methods,a comprehensive evaluation model is established to generate the optimal path and compare the original path.The results show that the optimal path generated by combining the two evaluation methods has a high fit with the original path.The highway route selection model based on AHP-entropy weight method has certain advantages in comparison.
