基于空间句法的视障群体街旁景观体验性评价

Landscape experiential evaluation of visually impaired groups base on spatial syntax

目前国视障群体占比高达0.9%,而户外导盲环境及视障群体景观体验设计仍面临导盲设施不完善、缺乏感官性体验等诸多挑战。以北京市官园桥周边15分钟生活圈为主要研究样本,利用Depthmap软件计算出视障者在该生活圈中两个地点之间(例如盲人按摩店到公园等)的最优路径,结合调研与访谈方式,构建视障群体对该出行路径的使用评价体系,从点状空间、线状空间、面状空间出发,提出视障群体景观体验设计策略。

At present,visually impaired groups account for as much as O.9%in China while the outdoor guide environment and the landscape experience design for the visually impaired still face many challenges,such as imperfect guide facilities and lack of sensory experience.This paper takes the 15-minute living circle around the Guanyuan Bridge in Beijing as the main research sample,and uses Depthmap software to calculate the optimal path for a visually impaired in the circle to travel from one place to another(e.g.,from the blind massage shop to the park,etc.).Combined with investigation and interview,an evaluation system for the use of the travel path for the visually impaired group is finally constructed,and the landscape experience design strategies of the visually impaired group are proposed in terms of point space,linear space,and plane space.
