| 摘 要： | 基于遥感影像数据, 提取宁波城区土地利用数据, 从扩展速度与强度、紧凑度等方面分析城市空间扩展特征, 选取区位环境、人口社会、产业经济和政府决策四方面分析宁波城市扩展驱动力. 研究发现: (1)宁波主城区城市空间扩展存在明显阶段性, 2000~2005年空间快速扩张, 此后扩展强度缓和; 外延式扩展方式造成了城市形态复杂, 紧凑程度较差. (2)受制于地形影响, 城市空间向东沿交通干道呈现廊道式扩张; GDP和常住人口是城市空间扩张的决定性因素; 产业结构、政府投资微弱地影响城市扩展趋势.

| Abstract: | The land use data of Ningbo urban area is extracted from the remote sensing image database to analyze the spatial expansion characteristics of the city in terms of expansion speed, intensity and compactness. The four aspects, including location environment, population and society, industry and economy, and government decision, are selected to study the driving forces of urban expansion in Ningbo. The study finds that: (1) Ningbo’s urban spatial expansion is advanced in a phase-wise manner, with rapid spatial expansion from 2000 to 2005, followed by a slow expanding momentum; the outward expansion results in complex urban patterns and poor space-planning. (2) Due to the influence of topography, the urban space expands corridor-like to the east with the improvement of transportation facilities; GDP and resident population are the decisive factors of urban spatial expansion, while industrial structure and investment less influence the momentum of urban expansion. |
