摘要:
伴随着西安城市服务辐射功能的不断加强,周边咸阳、渭南、铜川的相关区县已与西安形成紧密的经济、人口联系.本文从交通等时圈、城市吸引力、城镇人口密度、历史文化资源密度等4个角度出发,运用遥感(RS)、地理信息(GIS)、导航、人口经济统计等多源数据,采用多维定量计算的方法,考虑都市圈的发展能级、内部联系及空间集聚特征,以区县为单元进行测算,确定西安都市圈核心区、综合界定的西安都市圈空间范围.通过对西安都市圈空间特征提取与规律挖掘,首先运用交通等时圈法划定西安都市圈空间分析范围,其次通过城市引力模型初步定量测算西安都市圈核心圈层和扩展圈层,用经济社会数据计算研究区内各区县的综合实力,结合城市引力模型计算核心城区的吸引力范围,最后计算各区县的人口密度和历史文化资源密度,辅助调整西安都市圈核心圈层范围.结果表明基于多源数据源综合界定的西安都市圈空间范围更加具有合理性和科学性.
Abstract:
With the continuous enhancement of Xi’an’s urban service radiation function, the surrounding districts and counties of Xianyang, Weinan, and Tongchuan have formed close economic and population ties with Xi’an. This paper starts from the three perspectives of traffic isochronous circle, urban attractiveness and urban population density, using remote sensing(RS), geographic information(GIS), navigation, demographic economic statistics and other multi-source data.With multi-dimensional quantitative calculation methods to consider the development level, internal connections and spatial agglomeration characteristics of the metropolitan area and with districts and counties as calculation unit, the paper determines the core area of the Xi’an metropolitan area and the comprehensively defined spatial scope of the Xi’an metropolitan area. Through the extraction of the spatial characteristics and the rule generaliztion of the Xi’an metropolitan area, firstly, the traffic isochronous circle method is used to delimit the spatial analysis scope of the Xi’an metropolitan area. The data is used to calculate the comprehensive strength of the districts and counties in the study area, combined with the urban gravity model to calculate the attractiveness of the core urban area, and finally the population density of each district and county is calculated to assist in adjusting the core area of the Xi’an metropolitan area. The results show that the spatial scope of the Xi’an metropolitan area comprehensively defined on multi-source data sources is more reasonable and scientific.
