摘要:
面对城市滨水空间出现的空间活力衰退等问题,如何唤醒城市滨水空间活力、重塑人水和谐互动,是城镇化转型中城市空间品质提升的重要议题。手机信令大数据因其样本规模庞大、时空粒度精细、动态轨迹直观的特性,为城市滨水空间活力提升研究提供新视角。以苏州金鸡湖为例,利用手机信令大数据获取到的人群时空动态分布信息,分析滨水空间人群活力的时空特征。并进一步采用Pearson相关系数研究用地性质、交通设施丰富度、岸线可达性、服务设施数量等空间影响因子与滨水空间活力的相关性,发现影响空间活力最重要的因子是服务设施数量,同时交通设施丰富性也对空间活力提升有较好的促进作用。因此,在滨水空间规划和设计实践中应当关注公共服务设施对滨水空间活力激发的“触媒”作用,并鼓励滨水空间的复合式开发等策略。

Abstract:
In the face of declining urban waterfront space vitality, how to awaken the vitality of urban waterfront space and reshape harmonious interactions between man and water has become an important issue in improving the quality of urban space in the process of urbanization transformation. Due to the characteristics of high sample size, fine spatial-temporal granularity and intuitive positioning tracking, the mobile signaling big data provides a new perspective for the study of urban waterfront spatial vitality. Taking Jinji Lake in Suzhou as an example, this research analyzes the temporal and spatial characteristics of crowd vitality in the waterfront space with the spatial-temporal dynamic distribution information of population obtained from the mobile phone signaling big data. It further adopts the Pearson correlation coefficient to study the correlation between the spatial impact factors, such as land use nature, traffic facilities richness, shoreline accessibility, and service facilities quantity with waterfront spatial vitality. It has been found that the most important factor affecting spatial vitality is the number of service facilities. Meanwhile, the richness of transportation facilities also promotes the improvement in spatial vitality. Therefore, it proposes that in waterfront space planning and design, we should focus on the “catalyst” role of public service facilities to stimulate the vitality of waterfront space and encourage compound development of the waterfront space.
