    摘要:遗产空间网络的建构立足于城市文脉保护视角,以Arc GIS操作平台为工具。在文献梳理和现状调查的基础上对遗产资源进行筛选和主题分类,将道路的坡度、距离和类型作为评价路径构建适宜性的影响因子,运用最小阻力模型(MCR)计算综合阻力较小的道路作为网络路径。并结合道路环境和游憩需求划分步行车行路径、去除冗余线路,通过增加服务和景观缓冲节点对网络进行优化,形成哈尔滨中东铁路殖民遗产空间网络,为遗产空间网络构建和城市文脉保护提供可借鉴方法。 关 键 词:风景园林;城市文脉;殖民遗产;空间网络;哈尔滨;中东铁路;最小阻力模型

    Abstract:The building of heritage spatial network is based on the perspective of cultural route with Arc GIS Engine as the tool. To build a heritage spatial network, the investigation, classification, rating and sifting of the heritage resource points are needed in the first place, following which the analysis on terrain slope, length of paths and type of paths, which are set as factors to estimate the suitability of the paths, should be done. And then the network paths could be got using the minimal cumulative resistance (MCR) model. Considering the condition of the roads and the recreation needs of people, the paths are optimized through the screening and dividing of the pedestrian space cluster, together with wiping off redundant paths and adding service nodes. After that, the spatial network of the colonial heritage of Chinese Eastern Railway in Harbin is formed, offering a referential method for the building of heritage spatial network and the prevention of city context.
