基于梯度理论的北京通勤圈城市活力特征与影响机制研究
Urban Vitality Characteristics and Impact Mechanisms in Beijing's Commuting Circle:A Gradient Theory Perspective
摘要
Abstract
Urban vibrancy research has received significant attention in the field of urban planning;however,existing studies mainly focus on the city scale,with only a few adopting a cross-jurisdiction perspective.Using Beijing commuting circle(BCC)as an case,this study utilizes Tencent LBS data to construct urban vitality metrics,aiming to gain a deeper understanding of the spatial pattern of urban vital-ity.Through an examination of the tidal footprint of vitality,BCC is divided into three gradients of high-,medium-,and low-vitality zones based on the tidal foot-print,and the spatial characteristics of each zone are explored.Additionally,spatial regression models(SEM and SLM)are used to further investigate the impact mecha-nisms of urban vitality in different gradient zones.The key findings can be summa-rized into four points:Beijing,Tianjin,and a few other urban centers form a multi-centric pattern of urban vibrancy within BCC.Using Tiananmen Square as the cen-ter,we divide BCC into three gradient zones with radius thresholds of 8-22 km,32-68 km,and 94-134 km,respectively.Except for the Olympic area,the energy level of vibrancy centers is positively correlated with the gradient level and nega-tively correlated with the extent of their hinterland.Except for road density and land use mix,which exhibit significant positive correlations with the vitality level in all gradient zones,urban vitality is influenced by different factors in different gradient zones.The paper concludes by suggesting that targeted planning strategies should be adopted based on the vitality level and influencing factors.关键词
