基于GIS的山西省黄河板块旅游资源交通网络构建

Construction of Tourism Resource Transportation Network of the Yellow River Plate in Shanxi Province Based on GIS

以山西省黄河板块为研究区,运用层次分析法确定旅游公路选线影响因素的权重值,基于GIS空间分析法生成综合成本栅格数据集;采用矢量化叠加法提取黄河板块内优良旅游资源及行政中心;结合最小成本路径法,提取路径数量,分析统计路径分布情况.研究结果表明,旅游公路选线影响因素重要性由高到低依次为土地利用、地形条件、水文条件、现有公路网;研究区内优良旅游资源类型多样,其中建筑与设施,水域风光、地文景观、遗址遗迹、自然保护区占总数量比例分别为35.80%,23.46%,17.28%,12.35%,11.11%;提取最小成本路径121条,形成黄河板块内旅游资源交通网络,其中运城市和吕梁市交通网络较好.

Taking the Yellow River plate of Shanxi province as the research area,this paper uses the analytic hierarchy process to determine the weight value of influencing factors for the selection of tourist highways,and generates the comprehensive cost raster data set based on the GIS spatial analysis method.The excellent tourism resources and administrative centers in the Yellow River plate were extracted by vector superposition method.The minimum cost path method was used to extract the number of paths and analyze the distribution of paths.The results show that the importance of the factors influencing the selection of tourist highways is from the highest to the lowest:land use,topographic conditions,hydrological conditions,and the existing road network.There are various types of excellent tourism resources in the study area,among which buildings and facilities,water scenery,cultural landscape,sites and relics and nature reserves account for 35.80%,23.46%,17.28%,12.35%and 11.11%,respectively.121 routes with the minimum cost were extracted to form the transportation network of tourism resources in the Yellow River plate,among which the transportation networks of yuncheng and lvliang were better.
