摘要
以石家庄市区县为研究单元,以各区县内总道路网密度和加权道路网密度为主要指标,运用空间自相关分析、空间插值分析等方法研究了石家庄市县域道路网密度的空间分布差异,在此基础上,对道路网密度与地形及社会经济因素的相关性进行了初步分析。结果表明,(1)石家庄市各区县道路网密度的空间分布具有集聚特征;(2)石家庄市中部主城区为道路网密度高值区,东南部及西部为道路网密度低值区;(3)石家庄市道路网密度分布格局与地形地貌的地区分异大体吻合,与人口密度和GDP密度分布有一定的趋同性。
Taking counties (districts) of Shijiazhuang as the research unit,the total road density and weighted road density as the main index,using spatial autocorrelation analysis and spatial interpolation analysis,the spatial distribution characteristics of road density in the counties of Shijiazhuang City were studied.On this basis,the correlation between road network density and topography factors was analyzed.The results showed that:(1) the spatial distribution of road network are agglomerate;(2) the road density of central main urban area of Shijiazhuang City is high,while the southeast and west are low;(3) the distribution pattern of road density in Shijiazhuang City is roughly consistent with the regional differentiation of topography,population density,and GDP density.
