摘　　要：【目的】在建设城市健康街道的背景下,街道植物空间环境及其对步行质量的影响规律问题值得关注。【方法】选取武汉市9个街道植物空间样本,通过构建街道植物空间形态与步行愉悦度的特征评价体系,运用逐步回归分析、随机森林法等探索两者之间的影响规律。【结果】研究发现:1)街道植物空间形态评价体系分为尺度特征(面积、高宽比)、形状特征(形状系数)、界面特征(侧面Ⅰ通视率、侧面Ⅱ通视率、顶面通视率、绿视率);2)步行愉悦度评价体系包括满意度(0.2537)、放松度(0.2379)、舒适度(0.2144)、安全感(0.1629)、吸引力(0.1311);3)街道植物空间形态特征对步行愉悦度的影响因子包括绿视率、顶面通视率、面积、形状系数、高宽比、侧面Ⅰ通视率,影响权重分别为0.2885、0.2388、0.1841、0.1642、0.0995、0.0249。【结论】基于相关研究成果、调查分析结果等,提出以人性化理念为主导的基于步行愉悦度的大城市街道植物空间评价体系。同时,提出了4点街道植物空间的优化设计策略:1)选用植物要素构建或分隔街道空间,并控制乔木株距;2)控制街道植物空间的绿视率;3)重视街道植物空间边界形状的复杂度与丰富度;4)控制街道植物空间的高宽比。[Objective]In the context of healthy street,street plant space,as an integral component of street environment,has a significant influence on walking pleasure.Street plants or green spaces serve as the focus of the current researches on the relationship between walking pleasure and street plant area.At present,there is still a lack of systematic quantitative researches on and specific approaches for the evaluation of street plant space based on walking pleasure.Besides,there are few researches on the relationship between street plant space and walking pleasure.Therefore,it is necessary to discuss the characteristic evaluation systems for street plant space and walking pleasure,and to analyze the influence of street plant space on walking pleasure.Enriching the strategies for evaluation and design of street plant space based on walking pleasure can help promote the development and construction of healthy cities and healthy streets in China.[Methods]Through the comparative analysis of nine sample streets in Wuhan,including living,commercial and traffic streets,this research builds evaluation systems for street plant space and walking pleasure in Wuhan with the correlation there between being fully considered.Specifically,the research first establishes the evaluation system for the morphological characteristics of street plant space through literature review and judgment matrix methods.Then,the research screens relevant characteristics of street plant space and walking pleasure by literature review and expert methods.Additionally,the research collects sample streetscape images through field research,and obtains sample street panorama photos using PTGui and Photoshop software.Moreover,the research obtains data about the morphological characteristics of street plant space by grid method and image segmentation method.After that,the research collects characteristic data about walking pleasure by means of experiment,questionnaire and interview,and explores the influence of street plant space on walking pleasure by such me
