改革开放以来,中国经历了世界上速度最快、规模最大的城市化进程,西南山地城镇亦迅速扩张,万州区作为典型西南山地城市,其中心城区也经历了快速扩张.研究借助LEI(景观扩张指数)对重庆万州区1999-2005、2005-2011、2011-2017三个时段的建设用地扩张模式(内填式、蔓延式、跳跃式)进行分析,并对用地功能演化规律进行总结.结果发现,3个时段的MEI和AWMEI呈递增状态,万州中心城区1999-2017年间扩张过程中空间形态整体上趋于紧凑,不同功能片区和不同性质用地在不同的时段呈现不同扩张模式,以跳跃式和蔓延式最为显著.研究表明:①城镇以"蔓延式-跳跃式-蔓延式"的循环扩张模式突破山水阻隔;②不同功能的用地在扩张模式上具有明显的差异性;③在扩张方向上具有明显的大型交通基础设施导向性.

非建设用地管控途径探索--以佛山市顺德区为例

目前城市规划编制体系中,非建设用地往往是规划的"留白区",建设用地的"发展备用地",随着自然资源领域改革的不断深入,如何有效实施城乡非建设用地的规划管控,逐渐成为规划领域关注的重要问题.本文以顺德非建设用地管控为案例,提出非建设用地管控的主要困境在于其综合效益与建设用地存在级差,且现有管控手段和积累措施无法抑制用地性质转化的动因,并针对问题提出纳入法定规划体系、整体管控,对城乡非建设用地提出分类实
