Abstract The start point of research comes from the fact that urban space image can be represented by the text of written communication flow through statistics of word frequency. Furthermore, for the space image perceived by citizens, in the very great degree, urban function represented by all kinds of media indicates the selective transfer of space image conducted by different social groups. In this article, the author means to analyze the space image of the central urban areas of Shanghai, which is represented by the word frequency of place-names contained in the different kinds of written communication flow. Judging from study results of this article, space images contained in word frequency of place names in the Internet news show the basic characteristics of being in internet with the spatial structure of the central urban areas of Shanghai in the overall aspect, and the space image with place names as characterization symbols also displays the "container" property of various spatial elements.
Considering that the economic news text takes capital, government as the leading factor, and the internet post text takes the grassroots stratum as the leading factor, so the similarities and differences of space image in Internet news text and citizen vocabulary in internet posts essentially reflect differences of different social groups' cognition of space image of the city, and for the audience, the former text is a kind of dominant space image from the capital and government, and the latter is the image perceived in the daily life, and is a kind of behavior self-organized by the grassroots stratum to a larger extent. For the differences of these two kings of text, it can be seen that the space image in news text (dominated by the capital and government) has the feature of more structural centralized distribution, while the space image in citizen internet post text (dominated by the grassroots) shows a feature of more fragmented discrete distribution.
