历史建筑地标景观的可视化表达方法研究——以延安南关街片区为例

Research on Visual Expression Method of Historical Landmark Architectural Landscape--Take Nanguanjie District of Yan'an as An Example

历史建筑地标景观的可视化展示对于彰显城市文化特征、树立城市形象意义重大。以延安南关街片区为例,借助GIS平台对其历史建筑地标景观进行景观域面可视范围测度、景观视线廊道构建以及景观视野图景优化,从域面、轴线和焦点三个层面探析历史建筑地标景观的可视化表达方法与途径。研究表明,可视化分析方法可为景观表达提供数据基础和科学支撑,有助于营造增进视觉体验的可视空间语境,实现历史建筑地标景观的可见、可感与可意。

The visual display of historical architectural landmark is of great significance in showcasing the cultural characteristics of a city and establishing its image.Take the Yan‘an Nanguan District as an example,with the help of GIS platform,measure the visible range of the historical architectural landmark landscapes,construct the sight line corridors and optimize the landscape vistas.It explores the visualization methods and approaches of historical architectural landmark landscapes from three levels:domain,axis,and focus.The research shows that visual analysis methods can provide a data foundation and scientific support for landscape representation,helping to create a visual spatial context that enhances visual experience,and achieving the visibility,perceptibility,and meaningfulness of historical architectural landmark landscapes.
