以各类综合性新区、新型产业空间为代表的城市新区在城市外延式空间增长中发挥了重要作用。以879个城市新区为研究对象,对基于空间连续性与跳跃模式下的城市新区空间增长特征进行研究,结果表明:我国城市新区的空间增长模式可以分为边缘连续式、近郊跳跃式与远郊跳跃式;目前城市新区以5~20 km的近郊跳跃式为主,边缘连续式与远郊跳跃式居次;城市新区的跳跃程度同时受到新区自身功能与母城发展条件的双重影响。
New districts have played an important role in urban spatial expansion. The paper studies 879 new urban districts expansion and concludes three models: contiguous expansion, near suburban leaping expansion, and far suburban leaping expansion. Near suburban leaping expansion within 5-20 kilometers is the most common model. The leaping distance is affected by both new district function and mother town development.
