【摘要】：基于城市空间结构紧凑度和均衡度的概念构建城市空间增长绩效模型,遴选北京、重庆和深圳3个城市等级和地形迥异的大城市,分析其在2012—2016年的空间增长绩效。结果表明:北京的城乡区域逐渐融成一体,深圳的城市空间形态演变为多中心组团式的格局,而重庆的城市空间形态则相对紧凑。在此期间,北京的城市蔓延状况最严重,深圳的城市蔓延速度最快,而重庆则在社区级服务中心的配置上改善明显。空间增长绩效上,市区级紧凑度重庆最高,北京最低;社区级紧凑度深圳最高,北京最低;市区级均衡度北京最低,社区级均衡度重庆最低。
[Abstract]:Based on the concept of compact and equilibrium of urban spatial structure, this paper constructs the performance model of urban spatial growth, and selects three big cities with different levels and landforms of Beijing, Chongqing and Shenzhen. The results show that the urban and rural areas in Beijing gradually melt into one, and the urban spatial form of Shenzhen evolves into a multi-center cluster pattern. Chongqing's urban space form is relatively compact. During this period, Beijing's urban sprawl is the most serious, and Shenzhen's urban sprawl is the fastest. On the other hand, Chongqing has improved obviously in the collocation of community service centers. In the performance of spatial growth, Chongqing has the highest compactness in urban area and the lowest in Beijing; The compactness of community level is highest in Shenzhen and lowest in Beijing. Beijing has the lowest degree of balance at the urban level and Chongqing the lowest at the community level.
