摘　　要：城市街道空间是行人心理认知的核心载体,界面虚实关系的不同自然带来空间形态的差异,据此建立有关街道界面虚实特点的“界面节奏—心理认知”研究框架。在心理物理学的理论框架下,结合感受测量原理与空间知觉理论,得到街道界面节奏的“物理量—心理量”测算方法。以沉浸式虚拟现实技术进行心理认知实验,研究发现街道界面的中断次数、界面空间的延伸程度是最受行人瞩目的界面节奏特点,据此构建了频率与幅度参数相结合的定量方法,可为城市街道空间与行人心理认知相关研究提供理论基础与实践依据。Urban street space is the core carrier of pedestrians’ psychological cognition,the difference of virtual-real interface relations naturally brings about the difference of spatial morphology.Therefore,the research framework of “interface rhythm-psychological cognition” on the characteristics of virtual-real interface is established.The influence of street interface rhythm on psychological cognition mainly involves two aspects:one is the influence of geometric characteristics of urban street interface rhythm on pedestrians’ psychological cognition;the other is the quantitative method of urban street interface rhythm based on pedestrians’ perceptual law.Based on the description method of waveform graph,there are four main characteristics of street interface rhythm:the number of street interface interrupts,the spatial depth of street interface,the extended relationship of the street interface,the spatial distribution of street interfaces.Based on psychophysics and spatial perception theory,this paper attempts to construct a quantification algorithm that directly deduces “mental sensory quantity” from “physical stimulus quantity”.Under the framework of psychophysics,combining the principles of sensation measurement and spatial perception,the “physical quantity-mental quantity” measurement method of street interface rhythm is derived as follows:1) Mental quantitative methods based on psychophysical “the principle of perception measurement” and power law.The principle of perception measurement provides theoretical support and feasibility for the operation method of directly deriving sensory quantity (or degree) from physical stimulus quantity (or degree).The power law provides a bridge for equivalent conversion from “physical stimulus quantity” to “mental sensory quantity”.By substituting the specific value of stimulus quantity and related power index into the power law formula,the mental sensory quantity about this stimulus quantity can be solved.2) Mental quantitative methods based on
