摘要:
城市边界是城市演化认知和城市规划决策的空间依据。中国不少研究实践将地级市等行政地域范围视为城市,与物理上主要由连续人造不透水面构成的城市实体地域相比,存在较大的空间边界差异。然而,鲜有研究定量分析“实体”视角下长时间序列的城市用地演化,特别是对实体和行政两种统计单元视角下的城市扩张差异缺乏系统认识。本文基于30 m空间分辨率的多源遥感产品识别了1988—2018年8期的城市实体地域边界,分析其用地扩张过程,进一步与行政地域相对比,系统识别了两种统计视角下城市用地扩张的认知差异和空间模式。主要结论为:① 1988—2018年间,中国面积5 km2以上的城市实体地域单元数量增长了378%,以华东和华中地区的增长最为显著;城市实体地域中,88%为独立增长型,分布广泛但面积大都小于50 km2;12%为空间聚合型,主要分布在发达地区,面积普遍较大。② 相比行政地域,城市实体地域的位序规模更符合幂律分布,其Zipf指数30年来逐渐上升趋向于1,城镇体系发展愈发均衡;相比城市实体地域,行政地域单元在平原地区的城市扩张面积普遍偏高,在沿海地区的城市扩张强度普遍偏低。③ 和城市实体地域单元在拓扑关系上无法一一匹配的1327个行政单元大多分布在人口密集或发达的平原地区;结合实体和行政边界识别了“跨政区同城化”和“政区内集群化”两种扩张模式,前者多发生在省会区域,后者主要分布在华北平原,两者反映了城市化的空间重构。本文研究结果有助于深化中国土地城镇化时空过程的认识,并可对土地资源的科学配置、统一协调及行政区划的优化整合提供空间依据。
