基于GIS的山地城市网络空间覆盖格局及影响因素研究——以陕西省汉中市为例

Research on the Spatial Coverage Pattern and Influencing Factors of Mountain City Network Based on GIS——Take Hanzhong City,Shaanxi Province as an Example

网络覆盖的普及和发展给区域经济发展带来了新的契机。文章在GIS(GeographicInformationSystem,GIS)空间分析技术支持下,综合分析山地城市——汉中市网络覆盖空间格局及影响因素,推动其经济发展并加快城市信息化进程,为类似山地城市网络覆盖提供借鉴。结果表明:(1)汉中市网络覆盖空间集聚效果明显,主要表现为中心城区和郊县城镇区高度集聚,山地区域覆盖稀疏;(2)网络覆盖格局影响因子以人口因素和经济因素为主,土地利用、地形和交通因素为辅;不同区县、街道网络覆盖差异较大,网络覆盖高密度区呈现连片分布,逐渐向外变为低值;(3)交通路网对通信基站覆盖的影响显著大于宽带网络覆盖,主干道路对山地城市网络覆盖格局具有重要影响。

The popularization and development of network coverage has brought new opportunities for regional economic.This paper aims to promote its economic development and accelerate the process of urbanization informatization by comprehensively analyzing the spatial pattern and influencing factors of the network coverage from the mountainous city Hanzhong,with the support of GIS(Geographic Information System)spatial analysis technology,and to provide reference for the network coverage of similar mountain cities.The results show that:(1)The spatial agglomeration effect of network coverage in Hanzhong city is obvious,which is mainly manifested in the high agglomeration of the central urban area and the county seat,and the sparse coverage of the mountainous area.(2)The influencing factors of network coverage pattern are mainly demographic and economic factors,supplemented by land use,topographical factors,and traffic road network.The network coverage of different districts,counties and streets varies greatly.The high-density areas of network coverage are distributed in contiguous areas,and gradually becomes a low value outward.(3)The traffic road network has a significantly greater impact on the coverage of communication base stations than the coverage of broadband networks,and trunk roads have an important impact on the network coverage pattern in mountainous cities.
