基于KANO模型的海口市建成区滨海公共空间 景观需求评价

Assessment of Landscape Needs for Coastal Public Spaces in Haikou's Urban Areas Based on the KANO Model

在城市化快速推动下,人本需求日益成为城市建设的重要指导。以海口市建成区滨海公共空间为例,构建城市滨海公共空间景观品质评价指标体系,立足于人本需求视角,对滨海公共空间景观品质的需求进行定量研究,引入KANO模型开展问卷调查及现场访谈,判断滨海公共空间使用人群的需求程度,借助归类分析、混合类分析和Better-Worse指数,分析各需求的重要程度,并将指标按照必备需求>期望需求>魅力需求的属性重要度排序。结果显示,亲水性、可达性、植物配置丰富度等12项指标集中在必备需求和期望需求上。基于此,为提高海口市建成区滨海公共空间景观质量,根据需求重要性,针对自然环境、建成环境、活动主体3个要素提出了提升策略。

Driven by rapid urbanization,human needs have increasingly become a key guideline for urban construction.This paper presents an evaluation model for assessing the quality of coastal public spaces in urban development areas,focusing on the built-up coastal public spaces in Haikou.The study employs the KANO model to evaluate observed postconstruction comprehensively,conducts a survey,and holds on-site interviews with residents to identify different needs.The model employs classification,hybrid categories,and the Better-Worse index to assess the importance of each need,ranking them from Must-be Quality,through One-Dimensional Quality,to Attractive Quality based on their significance.The results indicate that twelve indicators,including hydrophilicity,accessibility,richness of planting design,and green ratio,are concentrated in the categories of Must-be and One-Dimensional Quality.Based on this,in order to improve the landscape quality of coastal public space in the built-up area of Haikou City,enhancement strategies are proposed for three elements of natural environment,built-up environment,and activity subject according to the importance of needs.
