As an essential part of the urban landscape, linear urban landscape (LUL) is the interaction between humans and nature, which is closely associated with daily life and brings multiple characteristics to visual perception. Current studies focus on complex models that describe visual perception using static viewpoints, but lossing the continuous and dynamic features of visual perception. This paper provides a general framework that can quantify dynamic visual perception based on urban morphology and improves accuracy in the descriptions of LUL linear spatial characteristics. Based on Beijing-Hangzhou Grand Canal (Hangzhou urban section), the proposed framework combines the indicators of multiple dimensions to quantify dynamic visual perception and emphasizes the continuity of LUL. To represent the dynamic visual perception and the spatial pattern characteristics of LUL, different evaluation criteria of indicators are set according to landscape scales. To minimize subjectivity and uncertainty caused by subjective cognition and fulfill the landscape pattern under different urban development policies, we set up distinct scenario preference patterns. With appropriate fine-tuning of scenario preference patterns and setting of movement types, the proposed method can be adapted to other LUL projects and aspires to provide a general methodology and scientific guidance for urban planning and landscape management.

基于城市形态的动态视觉感知评估线性城市景观

作为城市景观的重要组成部分,线性城市景观(LUL)是人与自然之间的相互作用,它与日常生活紧密相关,并为视觉带来多种特征。当前的研究集中于使用静态视点描述视觉感知的复杂模型,但是却失去了视觉感知的连续和动态特征。本文提供了一个通用的框架,可以基于城市形态量化动态视觉感知,并提高描述LUL线性空间特征的准确性。该框架以京杭大运河(杭州市区)为基础,结合多维指标对动态视觉感知进行量化,强调了LUL的连续性。为了表现LUL的动态视觉感知和空间格局特征,根据景观尺度设置了不同的指标评价标准。为了最小化由主观认知引起的主观性和不确定性,并在不同的城市发展政策下实现景观格局,我们建立了不同的情景偏好模式。通过适当地微调情景偏好模式和设置运动类型,所提出的方法可以适用于其他LUL项目,并希望为城市规划和景观管理提供一般方法和科学指导。为了最小化由主观认知引起的主观性和不确定性,并在不同的城市发展政策下实现景观格局,我们建立了不同的情景偏好模式。通过适当地微调情景偏好模式和设置运动类型,所提出的方法可以适用于其他LUL项目,并希望为城市规划和景观管理提供一般方法和科学指导。为了最小化由主观认知引起的主观性和不确定性,并在不同的城市发展政策下实现景观格局,我们建立了不同的情景偏好模式。通过适当地微调情景偏好模式和设置运动类型,所提出的方法可以适用于其他LUL项目,并希望为城市规划和景观管理提供一般方法和科学指导。
