【摘要】 针对当前面向城市热点空间分布特征与成因的研究缺乏考虑时效性和全面性的问题,该文提出了一种基于签到数据的城市热点探测方法,精准、便捷地探测到8种业态类型的城市热点,并在此基础上运用点模式分析和地理探测器等方法,对各业态类型城市热点的空间分布特征及其影响因素展开研究。研究结果表明:各业态类型的城市热点具有不同空间范围下的集聚性特征,且在空间分布上表现出明显的差异性;业态类型、GDP、人口规模、土地价格以及交通通达性是影响城市热点空间分布的重要因素,且同类因素对不同业态类型的城市热点的影响力不同。更多还原

【Abstract】 Aiming at the problem that current research on spatial pattern and contributing factors of urban hot spots is lack of timeliness and comprehensiveness,a systematic survey on urban hot spots detection based on check-in data was conducted in this paper.As a result,eight types of urban hot spots were detected accurately and conveniently.On this basis,the spatial pattern and contributing factors of eight types of urban hot spots were studied by using point pattern analysis,geodetector and so on.The results showed that various urban hot spots had the characteristics of agglomeration under different spatial scales,and showed obvious differences in spatial layout.The five factors such as format,GDP,population scale,land price and traffic accessibility,affected the spatial pattern of urban hot spots,and the same factors had different influences on urban hot spots of different formats.更多还原
