摘要
本文以陕西西咸新区为例,基于地理国情普查成果、高分辨率遥感影像和专题数据,以遥感和地理信息系统技术为支撑,结合路网密度和交通设施可达性两个测度交通网络发展情况的重要指标,分析和评价西咸新区交通网络的空间布局、配置密度和通达程度。结果表明:1)新区南部区域交通网络及设施发展整体较为成熟,而北部区域整体发展较缓慢;2)新区尚处于建设发展阶段,城市道路和等级道路递增,乡村道路递减;3)从新区内各新城的路网密度来看,沣东新城路网密度最高,沣西新城和泾河新城次之,秦汉新城和空港新城最低;4)新区当前的交通网络格局主要以航空、铁路、公路为主,机场、火车站和汽车站能够覆盖新区的大部分区域。今后应持续监测西咸新区的交通发展情况,为新区健康有序发展提供地理信息服务和辅助决策支持。
Taking Xixian New Area,Shaanxi Province as an example,this paper based on the results of the census of geographical conditions,high resolution remote sensing images and thematic data,supported by remote sensing and geographic information system technology,combined with the density of road network and accessibility of transportation facilities to analyze and evaluate the spatial layout,configuration density and accessibility of the transportation network in Xixian New Area.The results show that:1)The overall development of the transportation network and facilities in the southern part of the Xixian New Area is relatively mature,while those of the northern area is relatively poor;2)Xixian New Area is still under construction and development,with increasing urban roads and grade roads and decreasing rural roads;3)In terms of the road network density of each new towns in Xixian New Area,the Fengdong New Town has the highest road network density,followed by the Fengxi New Town and Jinghe New Town,and the Qinhan New Town and Airport New Town are the lowest;4)At present,the transportation network pattern of the new area is mainly based on aviation,railways,highways,airports,railway stations and bus stations can cover most of the new area.In the future,the traffic development of Xixian New Area should be continuously monitored to provide geographical information services and decision support for the healthy and orderly development of the new area.
