基于多维感知的城市广场景观要素优化策略研究

Research on Optimization Strategy of Urban Square Landscape Elements Based on Multidimensional Perception

在健康人居环境建设的背景下,城市广场景观要素对城市居民生活环境质量有重要影响。本研究的目的是分析城市广场景观要素的居民感知评价,提出相应的景观要素优化策略。以福州五一广场为例,基于多维感知的理论方法提取广场的23项景观要素作为广场使用者的评价对象,采用Kano-IPA景观要素评价问卷调查获取了使用者的主观评价数据。结果表明:广场使用者对声景要素和基础设施要素更为关注;机械声源的评价最低,是首要的景观优化对象,自然声景的营造有利于提升广场使用体验;基础设施是其次需要优化和维持其基本使用功能的对象;广场景观规划中资源分配的比重需要根据其优化后是否能提升使用体验而进行调整。该研究有利于指导城市广场的景观规划与设计,并为今后研究的开展提供新的思路。

Under the background of healthy living environment construction,urban square landscape elements have an important impact on the quality of urban residents’living environment.The purpose of this study is to analyze the residents’perception of urban square landscape elements and put forward the corresponding landscape elements optimization strategy.Taking Fuzhou Wuyi Square as an example,based on multi-dimensional perception,23 landscape elements of the square are extracted as the evaluation objects of square users,and the subjective evaluation data of users are obtained by using Kano-IPA questionnaire.The results show that:square users pay more attention to soundscape elements and infrastructure elements;mechanical sound source has the lowest evaluation,which is the primary object to be optimized;the creation of natural soundscape is conducive to enhance the user’s experience of the square;infrastructure is the second object to be optimized and maintained;the proportion of resource allocation in square landscape planning needs to be adjusted according to whether it can improve the use experience after optimization.This study is helpful to guide the landscape planning and design of urban square,and provides new ideas for future research.
