基于互联网媒介图像信息的多尺度城市夜景意象研究

[摘　要]城市夜景意象作为一个完整城市意象的必要组成部分，在城市形象建立与空间特色展示方面的作用正日渐受到规划界的重视。网络媒介的发展与数据信息传播的多样化，使城市意象不再依赖于个体的亲身体验，突破了传统空间的物理约束，在广域范围内被受众所感知。研究以珠海为案例，重点探讨两个议题：如何基于网络媒介(图片)数据包含的信息，对城市夜景意象作出基本特征识别与大众选择倾向？昼夜城市意象的时空差异如何体现？基于“四个空间尺度+两个时间维度”的分析架构，研究借助夜间遥感光强度数据和互联网搜索引擎中的图片景观数据，对珠海的城市夜景空间意象进行量化研究，分析人们对珠海夜间环境空间意象的感知差异。研究发现，城市夜景意象的城乡差异较大，市域与中心城区的空间集聚特征明显，并具有更为强烈的大尺度认知、地域城市特色倾向；人工标志性构筑物元素与山、海要素是夜景的主要内容。

Space Image Of Multi-Scalar Urban Nightscape Represented By Photo Landscape On The Internet/Li Yun, Zhao Miaoxi, Xu Yong, Chen Yulan
[Abstract] As the necessary part of urban image, and the well effect of urban image construction and spatial characteristics exhibition, urban nightscape image is get more attention. Depend on the development of network medium and diversification of data information spreading, urban image has been notice by more people in a more wide area. The paper takes Zhuhai as an example, discusses two problems: how to recognize nightsacpe image characteristics and people’s trend with the information from network medium or picture? how to describe the spatial-temporal changes during the day and night? Bases on the study framework of “four spatial scales+two time aspects”, uses the data of light intensity and landscape picture in search engine, the paper quantitative analyzes the nightscape image of Zhuhai, analyzes people’s different feeling. The result shows that, there is a big difference between urban nightscape and rural nightscape, urban field and central area have the obvious spatial agglomeration characteristic, and the stronger recognition and urban features trend; man-made symbolic elements, mount and sea are the main contents of nightscape.
