摘　　要：街道作为城市的骨架,是承载城市活力的重要载体.提升街道活力是提高城市居民幸福指数的重要举措之一.采用人口热力数据、街景图片、兴趣点(POI),从街道空间活力强度、美景度和基础设施完善度3个层面构建评价体系,对福州市鼓楼区的街道空间活力进行定性、定量评价.研究发现:鼓楼区整体活力呈"多心两带"的空间分布特征,二环以外街道人口热力较高,二环内侧由于城市空心化的影响,街道活力明显弱化;POI以三坊七巷为核心在空间上均呈凝聚型分布,二环以外的高密度核心区域急剧减少;鼓楼区街道整体美景度、满意度偏低,绿视率是影响街道美景度的重要因素;3项评价指标中,街道美景度、人口热力呈显著的正相关作用,与基础设施相比,营造优美的街道空间更能全方位地提升街道综合活力水平.As the skeleton of the city,the street is an important carrier for the vitality of the city.Improving street vitality is one of the important measures to improve the happiness index of residents in the city.Using population thermal data,Google street view images,and points of interest(POI),an evaluation system was constructed from the three levels of street space vitality intensity,street beauty degree and infrastructure perfection to qualitatively and quantitatively determine the street space vitality in Gulou District,Fuzhou City.The study found that:firstly,the overall vitality of Gulou District is characterized by the spatial distribution of"multi-centered and two-zones".The population thermal of streets outside the second ring road is relatively hot,and the inner side of the second ring road has significantly weakened due to the hollowing out of the city.Secondly,POI is spatially condensed with Three Lanes and Seven Alleys as the core,and the high-density core area outside the second ring sharply decreases.Thirdly,the overall beauty degree and satisfaction degree of the streets in Gulou District are low,and the green viewing rate is an important factor affecting the beauty of the streets.Finally,among the three evaluation indicators,street beauty degree and population thermal have a significant positive correlation.Compared with infrastructure perfection,creating a beautiful street space can improve the overall vitality of the street in an all-round way.
