摘 要:以安徽省为研究区域,选取1995,2005,2013年3个时间断面的路网密度数据为评价指标,基于GIS空间分析技术,探究安徽省路网时空格局演化特征.研究表明:1)路网密度整体呈上升趋势,从北向南依次降低,地区分布存在空间分异,呈现由">"形向"ヨ"型转变的空间分布格局.2)路网分布具有阶段性特征,不同研究阶段指向性不同,以铁路和高速公路指向性为主,在交通道路沿线地带构成路网最优区域.3)全局自相关分析表明,路网空间布局集聚特征显著;局部自相关分析表明,路网分布呈现异质特性规律,异质特性区域在研究阶段增多,区域内部路网发展不均衡,格局进一步破碎化.Taking Anhui 78 node towns as the study area,selecting the road network density data of 1995,2005 and2013 three time section as evaluation index,the evolutionary characteristics of the road network space-time pattern in Anhui are explored based on GIS spatial analysis techniques.The results show that:road network density as a whole is on the rise,the overall descending order is from north to south,there are different spatial distributions in the area,which presents from " >" shape to " ヨ" shape spatial distribution.The distribution of road network has the characteristics of stage,different research stages has different directivity,mainly to depend on railway and highway directivity,the optimal area of road network is constituted along the traffic roads.The global autocorrelation analysis shows that the accumulation of the spatial distribution of the road network is significant,and the local autocorrelation analysis shows that the distribution of the road network is heterogeneous.The heterogeneous characteristic area is increased during the research stage,and the regional network development is uneven and the pattern is further broken.
