【摘要】 为了获得全国公路交通网络空间分布特征和趋势变化,以国家1:50000地形数据库的公路交通数据(2012~2015年4个时间序列)为研究对象,利用空间自相关的统计方法对其展开分析研究。实验结果表明全国公路交通网络的空间分布具有显著的空间自相关性和聚类特征,同时其分布与区域经济指标存在空间显著正相关。更多还原

【Abstract】 In order to obtain spatial distribution characteristics and trend of national traffic network, this paper takes traffic data of national 1:50 000 topographic databases(time series from 2012 to 2015) as the research object. The analysis and research are based on the statistical method of spatial autocorrelation analysis. The experimental result shows that the spatial distribution of national traffic network has a significant spatial autocorrelation and clustering characteristics, and its distribution is significantly positively correlated with the regional economic indicators.更多还原
