- 摘要:
- 作为典型的山地城市，重庆市自改革开放的近30 a内，区域建设用地的数量发生了很大变化，因此对其建设用地蔓延情况进行详细的了解十分必要。通过构建拓扑关系指数区分建设用地蔓延类型，分析了1978—2007年不同研究时段、不同区域的建设用地在平面和立面的蔓延特征。结果表明，研究区建设用地从5 885.69 hm2增加到29 347.47 hm2；跳跃型发展是建设用地主要的蔓延类型；建设用地的蔓延使得区域建设用地的重心在竖向方向上由1978年的250.40 m升高到2007年的284.61 m。近30 a来重庆城区的建设用地增长迅速，建设用地的重心不断抬升，可能会影响到区域的生态安全，因此需从规划的角度对城市扩展进行科学合理的指导。
- Abstract:
- As a typical hilly city, Chongqing experienced a dramatic expansion about its built-up area in the recent 30 years after the implement of the open-door-policy. It’s necessary for us to understand the expansion of its built-up area. A method about how to divide the built-up area expansion considering the spatial topological relations between 2 built-up area objects was conceived and the the sprawl of built-up area in the horizontal and vertical direction was analyzed. The result of this study indicated that: (1) the built-up area expanded from 5 885.69 hm2 to 29 347.47 hm2 in the study region; (2) outlying sprawl was the main sprawl type; (3) the built-up area centroids of different periods elevated from 250.40 m to 284.61 m in the vertical direction from 1978 to 2007. The conclusion was that the built-up area of a typical mountain city expanded dramatically afar the implementing of open door policy in Chongqing city, the dramatic transform of land use may affect the regional ecology security, it is also very important to guide the urban expansion from the plan perspective.
