基于OD成本矩阵路径映射的城市游赏递级路径系统构建与优化方法研究

Study on the Construction and Optimization of Graded Tour Path System Based on OD Cost Matrix Path Mapping

太原府城承载着太原2500年建城史积淀的璀璨历史文化,是太原城内最能体现城市发展脉络的公共空间,也是城市中最具步行游赏气质的区域之一。在城市化发展进程中,府城内的文化资源逐渐衰败、街巷空间肌理被蚕食。本次规划通过分析府城街巷的步行适宜性和街巷吸引度,建立街巷综合游赏度评估模型模型,形成街巷综合游赏潜力底图。在此底图基础上,运用ArcGIS平台OD成本矩阵分析方法,以府城内分级文旅资源点为节点,形成OD成本矩阵运算包络线及其对应的点对路径,构建太原府城宜行宜游的"核心路径+延伸路径"的递级路径系统,并通过与相关保护规划的对比,进一步校核优化滨河文化游赏路径的路径选择。

Taiyuan Fucheng carries the bright history and culture of the city’s history of 2500 years.It is the best public space to presents the urban development context.It is also one of the most walkable areas in the city.During the Urbanization process,the cultural resources in Fucheng are gradually declining and the spatial texture of streets is eroded.This paper tries to modeling an evaluation of based on the street walkability and attractiveness.This model builds a potential base map.We use the OD cost matrix to form an envelope between cultural resource points,and form a graded path system.This system combines core routes as well as extending routes.We also take the master plan and protection plan into consideration,which can optimize the path system.
