长沙市城市意象知觉矩阵分析与聚类分析

Perceived Matrix Analysis and Hierarchical Cluster Analysis on the Urban Image of Changsha City

通过问卷调查和知觉矩阵分析的方式,试图对长沙市的整体城市意象进行定量研究。随后的聚类分析印证了这一结果:(1)在特殊文化遗产与古迹的知觉矩阵图中,大部分意象元素集中在第一和第三象限中,说明这些元素的保护工作处于两个极端(或者具有强烈的意象作用,或者市民们基本上不知道它们的存在)。(2)整体水域的品质偏低,说明水域整治急待加强,对于重要度颇高的湘江和橘子洲头更是如此。(3)城市地标的情况同特殊文化遗产与古迹的情况相似,说明大量标志物的意象品质有待提高。最后,对处于各个象限的意象元素分别提出了相应的整治对策。

This paper tries to analyze the urban image held by Changsha inhabitants after questionnaire and perceived matrix analysis, and then a hierarchical cluster analysis has proven the following results： （1）Most elements of urban image in the perceived matrix about special cultural legacies and historic sites concentrate in the first or the third quadrant,which indicates that the maintenance of these elements is at the extreme-either good or bad. （2）The quality indexes of the integral water areas are low,especially the ones with high importance index,namely the Xiangjiang River and the Mandarin - Orange Islet. （3）The position of elements of Land marks on the perceived matrix is similar to that of special cuhural legacies and historic sites,which indicates that their quality must be improved. At last this paper provides some suggestions on improvement and construction of the urban image elements.
