摘要:
从景观视觉特征的多义性入手,指出景观视觉感知的内隐特征与研究难点。参考“旅游凝视”理论将旅行照片作为视觉表征媒介,研究观察者对于旅游地景观视觉感知的偏向性如何构建。大数据时代数字足迹的普及,使旅行者上传到互联网社交平台的评论信息及地理信息标记照片成为研究景观视觉感知的重要数据来源。基于此,从3个方面展开研究。1)将2种类型数字足迹纳入传统景观评价框架,并从物像、视像与心像之间的转化过程及其关联机制等方面对景观视觉感知评价方法进行创新。以南京历史城区范围内的秦淮河风光带为研究对象,通过质性分析工具NVivo对数字足迹文本内容中蕴藏的景观感知要素进行编码识别,使用定性分析软件RQDA对旅行照片进行编码处理。2)融合专家与公众视角,从自然景观价值、历史文化价值与社会经济价值3个维度构建秦淮河风光带景观视觉感知评价体系。3)从景观资源分级界定与分类管控的视角,对该评价体系的应用潜力进行分析。研究指出:基于专家与公众视角融合的景观视觉特征分析及基于景观视觉感知评价的设计思考,对于旅游地景观研究与形象提升具有重要意义。

Abstract:
In view of the ambiguity of visual landscape characteristics, this research points out the implicit characteristics and research difficulties of visual landscape perception. Based on the theory of “tourist gaze”, the research adopts travel photos as a visual representation medium to explore how to build observers’ preference toward the visual perception of tourist landscape. The popularity of digital footprint in the era of big data has made the comment information and geo-tagged photos uploaded to the Internet by travelers an important data source for studying the visual perception of landscape. Based on this, the research: 1) incorporates two types of digital footprints into traditional landscape evaluation framework, innovates the evaluation methods for visual landscape perception from such aspects as the transformation process and correlation mechanism between object image, visual image and mental image and, taking Qinhuai River Scenery Belt within the historic urban area of Nanjing as the research object, codes and identifies the landscape perception elements contained in the text content of digital footprints by NVivo (a qualitative analysis tool), and codes travel photos by RQDA (a qualitative analysis software); 2) builds an evaluation system for visual perception of landscape in Qinhuai River Scenery Belt from the three dimensions of natural value, historical value and socio-economic value by integrating the perspectives of experts and the public; 3) analyzes the application potential of the aforesaid evaluation system from the perspectives of classification definition and control of landscape resources. The research concludes that the analysis of visual landscape features based on the integration of expert and public perspectives and the design thinking based on the evaluation of visual landscape perception are of great significance to the landscape research and image improvement of tourist destinations.
