【摘要】：基于道路网络图件数据和相关统计数据,结合ArcGIS,GeoDa和SPSS软件,运用叠加分析、空间插值分析、趋势面分析及空间自相关分析等方法分析了内蒙古自治区道路密度空间格局特征.结果表明:内蒙古自治区道路密度呈现显著的空间自相关性,呼包鄂地区、赤通地区和呼伦贝尔市中部地区成为道路密度的热点集中区,其他地区是冷点集中区;道路密度呈现出东西两边低中部高,南高北低的趋势;且在空间分布上存在集聚特征.在研究结果的基础上,深入分析了内蒙古自治区道路密度空间格局特征形成机理,经济发展、人口和交通固定投资是影响内蒙古道路密度空间格局的重要因素.
[Abstract]:Based on road network map data and related statistical data, combined with ArcGIS,GeoDa and SPSS software, using overlay analysis, spatial interpolation analysis, Trend surface analysis and spatial autocorrelation analysis are used to analyze the spatial pattern characteristics of road density in Inner Mongolia Autonomous region. The results show that the road density of Inner Mongolia Autonomous region shows significant spatial autocorrelation. Hubao Hubei area, Chitong area and the central region of Hulunbeir City become the hot spots of road density concentration area, while the other areas are cold spot concentration area. The road density tends to be high in the middle and middle of the east and west, high in the south and low in the north, and the spatial distribution has the characteristics of agglomeration. On the basis of the research results, the formation mechanism of the spatial pattern of road density in Inner Mongolia Autonomous region is deeply analyzed. The economic development, population and fixed investment of traffic are the important factors affecting the spatial pattern of road density in Inner Mongolia.
