摘要
多元技术的融合应用已成为城乡规划学科实践的发展趋势。研究以桂林城区至阳朔县郊野区域的旅游绿道网选线规划为例,利用层次分析法、德尔菲法、POI数据爬取方法、ArcGIS技术、适宜性评价等方法来解决绿道网选线空间布局的问题。首先通过层次分析法构建绿道网选线适宜性评价模型,结合德尔菲法获得专家打分,以此计算绿道影响因素的一级、二级指标权重;其次,将指标权重值、爬取的POI矢量数据、91卫图助手软件下载的地理高程和卫星影像数据导入ArcGIS软件,进行适宜性分析,最终获得绿道选线综合适宜性评价结果。这些定量分析方法是对定性信息的有效补充,期望对其他绿道选线的规划实践提供借鉴。
The integrated application of multiple technologies has become the development trend for the practice of urban and rural planning discipline.Taking the route selection planning of tourism greenway network from Guilin urban area to Yangshuo rural area as an example,the paper uses AHP,Delphi method,POI data crawling method,ArcGIS technology and suitability evaluation method to solve the problems in the spatial layout of greenway network route selection.Firstly,an evaluation model for the suitability of greenway network route selection is constructed with the analytic hierarchy process,and expert scores are obtained with Delphi method to calculate the weights of the primary and secondary indexes of the influencing factors of greenway.Secondly,the index weight value,POI vector data crawled,geographic elevation and satellite image data downloaded from 91 satellite map assistant software are imported into ArcGIS software for suitability analysis.Finally,the comprehensive suitability evaluation result of greenway lines selection is obtained.These quantitative analysis methods are effective supplements to qualitative information.It is expected to provide a reference for the planning practice of other greenway route selection.
