摘要

采用1957与1982年的地形图和1995与2008年两时相的卫星影像提取城镇建设用地信息,运用ArcGIS建立广佛都市区路网与建设用地数据库。采用相关性分析方法,定量地分析广佛都市区道路密度与建设用地之间的影响。结果表明,道路密度和城镇建设用地比重两个变量系数之间呈高度的线性正相关关系,不同年份区镇的道路密度与城镇建设用地具有相互影响关系。道路密度高的区域一般对应城镇建设用地密集的区域,道路密度发展快的区域一般对应城镇建设用地扩展快的区域。从1957-1982年和1982-1995年两个时期来看,道路发展较快分区要多于城镇建设用地扩展较快的分区,城镇建设用地的扩展稍滞后于道路发展,城镇建设用地的扩展受道路发展的影响。1995-2008年时期城镇建设用地迅速发展,较快发展的分区明显多于道路发展较快的分区,城镇建设用地的扩展也反作用于道路的发展。

Abstract

Relationship between traffic road and urban land use expansion is complex and uncertain. Traffic road plays an important role in transportation and is a major driving force of urban land use expansion. Therefore, traffic road has great impact on urban expansion and development. Also, urban expansion has new demands for the development of traffic road. The paper tries to analysis the interaction between road network and urban construction land in Guangzhou-Foshan metropolitan area, to reveal the structural feature and evolution law of urban construction land in different developing stages of road network under multiple-core synergism. Based on topographic maps of 1957 and 1983, and remote sensing images acquired in 1995 and 2008, the normalized thematic data of road network were extracted. These road network data and construction land data were stored in database which was built up in ArcGIS. Using correlation analysis method, we quantitatively analyzed the interaction between road density and urban construction land expansion. The results show that: The variable coefficients of road density and urban construction land proportion present a highly positive linear relationship. Different years of road density and urban construction land expansion have an interrelationship. Districts with high road density correspond to the districts with intensive urban construction land. Districts with rapid development of road density correspond to the districts with rapid expansion of urban construction land. From the first two periods, the number of districts with rapid development of road density is bigger than the number of districts with rapid expansion of urban construction land. Compared with the development of road, the expansion of urban construction land has a slight delay. The expansion of urban construction land is stimulated by road development. During the last period, urban construction land expanded rapidly. The number of districts with rapid expansion of urban construction land is bigger than the number of districts with rapid development of road density. The expansion of urban construction land stimulates road development.
