基于街景图片的城市街道空间品质对比研究

Comparative Study on the Spatial Quality of Urban Streets Based on Street View Images

街道是城市公共空间的重要组成部分。为了深入了解长春市街道空间品质水平和特征,为今后改造提升提供数据支撑和借鉴,选取上海中环、武汉三环、哈尔滨四环和长春四环作为研究对象,基于街景图片构建了街道空间品质评价测度指标体系,并对不同城市街道空间品质展开了定量评价与对比。结果表明,上海综合街道空间品质最好,其次为武汉,哈尔滨和长春街道空间品质较差;长春市高品质街道占比最少,且呈“点—线”分布,聚集连续性较弱,支路街道品质明显较差,需要得到重视和改善。

Street is an important part of urban public space.In order to understand the level and characteristics of street spatial quality in Changchun City and provide data support and reference,taking Shanghai central road,Wuhan third ring,Harbin fourth ring and Changchun fourth ring as the research objects,we constructed the street spatial quality evaluation index system based on the street view images,and carried out quantitative evaluation and comparison.The results show that the spatial quality of Shanghai is the best,followed by Wuhan,Harbin and Changchun.Changchun City has the lowest proportion of high quality streets,which are distributed as“point to line”with weak agglomeration continuity.The quality of branch streets is obviously low,which needs concerns and improvements.
