基于骑行视觉感知的绿道景观意象评价——以武汉东湖绿道二期为例

Evaluation of Greenway Landscape Image Based on Cycling Visual Perception: A Case Study of Wuhan East Lake Green Road Phase Ⅱ

东湖绿道是武汉市民亲近自然的"生态绿心"。目前绿道一、二期已投诸使用,三期的提升工程需以前期的使用后评价作为参考。该文从骑行者视觉感知的需求角度出发,通过现场问卷和拍摄记录的调研方式,从骑行者社会特征、行为特征以及景观要素特征三方面探究其感知结果的影响因素,继而通过语义评价法、图片分析法提取不同类型绿道的骑行感知特征,研究发现:不同类型绿道生成不同景观意象结构,并与视觉要素中自然要素的设计紧密相关。

The East Lake Greenway is the "ecological green heart" of Wuhan residents who are close to nature. At present, the first and second phases of the greenway have been put into use, the third phase of the promotion project needs to be evaluated after the early use as a reference. Based on the needs of the visual perception of the cyclists, we explore the influence factors of the cyclists’ perceived results from three aspects of social characteristics, behavior characteristics and landscape feature characteristics through the research method of the on-site questionnaire and the shooting record. Then we extract the cycling perception characteristics of different types of greenway through semantic evaluation and picture analysis. The study found that different types of greenways generate different landscape image structures, which are closely related to the design of natural elements in visual features.
