【摘要】：基于道路網(wǎng)絡(luò)圖件數(shù)據(jù)和相關(guān)統(tǒng)計數(shù)據(jù),結(jié)合ArcGIS,GeoDa和SPSS軟件,運用疊加分析、空間插值分析、趨勢面分析及空間自相關(guān)分析等方法分析了內(nèi)蒙古自治區(qū)道路密度空間格局特征.結(jié)果表明:內(nèi)蒙古自治區(qū)道路密度呈現(xiàn)顯著的空間自相關(guān)性,呼包鄂地區(qū)、赤通地區(qū)和呼倫貝爾市中部地區(qū)成為道路密度的熱點集中區(qū),其他地區(qū)是冷點集中區(qū);道路密度呈現(xiàn)出東西兩邊低中部高,南高北低的趨勢;且在空間分布上存在集聚特征.在研究結(jié)果的基礎(chǔ)上,深入分析了內(nèi)蒙古自治區(qū)道路密度空間格局特征形成機理,經(jīng)濟發(fā)展、人口和交通固定投資是影響內(nèi)蒙古道路密度空間格局的重要因素.
[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.
