摘　　要：在城市健康街道及步行友好型街道建设的人本视角下,街道空间的优化设计逐渐成为城市规划研究的热点。绿视率作为街道可步行性的评价要素之一,可以对步行者的心理产生影响,同时,步行愉悦度可以用于描述步行者的心理。研究通过对武汉市生活型、商业型、交通型三类街道共9个样本进行比较分析,分析街道步行空间绿视率与步行愉悦度的特征,以及二者之间的关联。结果表明,街道步行空间的平均绿视率与步行愉悦度呈显著正相关,当绿视率达到0.1425后,步行愉悦度为正,反之为负;街道步行空间的绿视率标准差与步行愉悦度无显著相关关系。最后以提升步行愉悦度为导向,针对街道共性问题和不同类型街道的个性问题提出街道步行空间绿化的具体建议,同时提出三个方面的优化策略,以期提高街道步行空间绿视率,提升步行愉悦度。研究为提升街道步行空间绿视率及步行愉悦度提供了理论依据及策略参考,对城市街道的人性化建设具有一定的参考价值。Street space is one of the important components of urban space and an important outdoor space for urban residents’social activities.With the revival of slow traffic,the advocacy of“lowcarbon travel”,and the proposal of healthy street strategies,the construction of street space has received renewed attention.At the same time,the optimal design of street space has gradually become a hot spot in urban planning research.As one of the evaluation elements of street walkability,green view has an impact on the psychology of pedestrians.And walking pleasure can be used to describe the psychological.The green view data was obtained by analyzing street view images captured by cameras simulating the perspective of pedestrians,and extracting the green part of the image.Factors influencing walking pleasure were screened:safety,comfort,relaxation,attractiveness,and satisfaction.Then their weights were determined by Delphi method:0.1097,0.2408,0.2718,0.0590,0.3186.In order to ensure the diversity and representativeness of the samples,three types of streets were selected:lifestyle streets,commercial streets,and traffic streets,with a total of 9 samples,located in Wuhan.The seven-level Likert scale was chosen to allow subjects to rate the factors that affect walking pleasure for each sample.Then the walking pleasure is obtained by calculation.First,the characteristics of the green view and walking pleasure of samples are analyzed.The evaluation of the characteristics of the green view of samples is divided into two parts:the average value and the change rate.The results show:1)Averages green view are in the range of 0.0564-0.3781,and the green view of lifestyle streets are relatively high.2)By observing the change trend chart of the green view,it is found that the three types of streets present different changing laws of the green view.Standard deviations of green view are mostly concentrated in 0.08-0.12,the standard deviation of the street green view has little correlation with the street type.3)Generally,the higher the av
