《清明上河图》城市意象的网络图景分析

互联网媒介是网络社会中重要的信息获取渠道，在新媒体的作用下，社会个体感知城市的方式发生变化，并拓展了城市意象的研究范畴。以互联网搜索引擎中《清明上河图》古代城市意象图片为研究对象，首先探索性地提出解析网络媒介数据中城市意象再表达的分析方法，包括场景图片的叠合分析、高频分析与要素提取；其次，以《清明上河图》为实证研究对象，揭示网络媒介中公众对于古代城市意象的认知特征。结果显示，公众对历史图景中空间意象的认知高度集中在街道、桥头与城楼等特征性标志物和节点空间，反映了“流动空间”中凯文·林奇城市意象体系的结节性特征。更重要的是，空间意象的社会建构过程也是当前历史街区中地标性建构筑物“符号化”趋势的直接表现。

Internet Analysis of City Image in "Qingming Shanghe Tu" of Qing Dynasty

Internet media has become an increasingly important access to information. It not only has a direct impact on the way people perceive the city but also become a special object of urban image research. In this paper, the ancient city images reflected in the "Qingming Shanghe tu" in the network search engine are studied to show the spatial imagery cognitive characteristics in the network society. The purpose is to propose a new method to analyze the re-expression of urban images in network media data, and to explore the public perception and re-expression of these ancient city images. The result shows that the focuses are highly concentrated on certain landmarks and node areas, which conforms to Kevin Lynch for the city image theory. It also reflects the phenomena that the public perception of historical areas and professional focuses are highly signalized in the process of social construction.
