摘要

Highly dense cities' livability has long been debated in the urban planning field, particularly regarding vibrancy, walkability, and day-to-day service access. However, studies on density's effects on the provision of neighborhood community amenities and services are limited. In addition, urban form's effects on community facility distribution patterns under the constraints of pedestrian access to urban road networks remain poorly understood. Hong Kong, with an average population density of 68,500 persons/km(2), has one of the world's densest urban environments. This study investigated community facility distribution through a comprehensive network analysis using fine-scale dataset. Results showed that highly dense urban form ensured access to certain facilities and services and that daily service and amenities provision was positively correlated to building density and performance of community spatial characteristics. The findings provide insights for planning and designing to provide better facility services to meet people's daily needs regarding amenities and services and for the configuration of a dense urban form. 长期以来，高密度城市的宜居性一直是城市规划领域争论的焦点，特别是在城市活力、可步行性和日常服务的可达性方面。然而，有关城市密度对社区设施和服务提供的影响的研究相对有限。此外，在限制行人进入城市道路网络的情况下，人们对城市形态影响社区设施的分布格局的依然认识不足。香港的平均人口密度为每公里68,500人，是世界上人口密度最高的城市之一。此项研究采用精密标度的数据集，通过全面的网络分析对社区设施的分布情况进行了调查。结果表明，高密度的城市形态确保了一定的社区设施和社会服务的可获得性，日常服务和设施的便利性与建筑密度和社区空间特征的效能呈正比关系。此项研究结果为城市规划和设计出更好的社区设施和服务提供了建议，以满足高密度城市中人们对设施和服务的日常需求。
