【摘要】：设定交通可达性指数及交通区位优势度、内部交通连通度和对外通达性3个分指数,全面测度海南各县级行政区的交通可达性,在此基础上,采用Global Moran’s I和Getis-Ord Gi*指数分析与全局趋势分析方法,从多个维度系统研究海南交通可达性空间分异现状格局。结果显示,目前海南各县级行政区交通可达性差异很明显;海南岛交通可达性总体呈沿海内陆分异与北南方向类似U型分异格局,交通可达性的3个分指标均存在鲜明的空间分异特征,即交通区位优势度与交通可达性总体分异格局基本一致,内部交通连通度呈北部较高、中部内陆到西南沿海较低而东南沿海居中的分异格局,对外通达性呈沿海内陆分异及北南和东西方向双重类似U型分异格局;三沙市是海南一个特殊的沿海地级市,其交通可达性很差。地形地貌、经济发展水平、人口和政治因素对海南交通可达性空间分异产生了明显的影响。推进海南经济发展需要充分利用交通条件进行经济空间布局引导,并逐步增强交通布局的空间均衡性。
[Abstract]:Set up three sub-indexes of traffic accessibility index and traffic location advantage, internal traffic connectivity and external accessibility, and comprehensively measure the traffic accessibility of each county administrative district in Hainan, and on this basis,By using Global Moran's I, Getis-Ord Gi* index analysis and global trend analysis, the spatial differentiation pattern of traffic accessibility in Hainan was studied from multiple dimensions.The results show that there are obvious differences in traffic accessibility among county administrative regions in Hainan at present, and the traffic accessibility of Hainan Island is generally similar to the U-shaped differentiation pattern in the coastal inland area and the north-south direction.The three sub-indexes of traffic accessibility all have distinct spatial differentiation characteristics, that is, the traffic location advantage degree is basically consistent with the overall traffic accessibility differentiation pattern, and the internal traffic connectivity is higher in the north.The pattern of differentiation from the central inland to the southwest coast is lower than that of the southeast coastal area, and the external accessibility is the coastal inland differentiation and the north-south and east-west direction are similar to the U-type differentiation pattern, the Sansha city is a special coastal prefecture-level city in Hainan.Its traffic accessibility is poor.Topography, economic development level, population and political factors have a significant impact on the spatial differentiation of traffic accessibility in Hainan.To promote Hainan's economic development, it is necessary to make full use of traffic conditions to guide the economic spatial distribution and gradually enhance the spatial balance of traffic layout.
