深圳经济区城市腹地划分与演变研究

Partition and Evolution of the Hinterland of Shenzhen Special Economic Zone

在深圳市特区一体化背景下,运用主成分分析法测算城市综合影响力指数。考虑了道路类型及地形阻抗,在GIS软件支持下,利用Huff模型,进行基于时间可达性的深圳经济特区城市腹地划分及演变分析,并提出了相应的城市空间发展策略。结果表明,场强最大等值线与10 min OD时间成本等值线基本重合;城市腹地与行政区域不存在显著的空间相关性;城市综合影响力的绝对优势及交通环境的改善,使得大鹏新区大部分区域成为罗湖区在深圳东海岸的腹地孤岛;特区一体化背景对深圳市中心区城市腹地变化影响显著,原特区的罗湖、福田和南山的城市腹地已形成相对稳定态势,但随着特区一体化推进,原特区外的宝安和龙岗两区逐步削弱了南山区、盐田区、罗湖区的腹地范围。

Under the background of special regional integration of Shenzhen,the article calculated the urban comprehensive influence index by principal component analysis,and used Huff model to divide the urban hinterland of Shenzhen special economic zone on the base of time reach ability supported by GIS software considering the road types and terrain resistance,urban space development strategy proposed later.The results show that potential energy maximum contour roughly coincided with 10 minutes OD cost contours.Hinterland area of administrative district is positively correlated with its urban comprehensive influence index.Absolute advantage of urban comprehensive influence index and the improvement of the transit environment,make most regions of Dapeng District a Shenzhen East Coast hinterland island of Luohu District.Hinterland of Shenzhen Special Economic Zone under the background of special regional integration changed significantly.Hinterland of Nanshan and Yantian Districts gradually weaken attributable to Baoan and Longgang Districts outside primary special economic Zone.
