【摘要】：基于交通地理学的基本理论和GIS技术,构建跨省山区空间阻隔可达性模型,并以跨滇川黔三省的乌蒙山区42个县(市、区)为研究个案进行分析。结果表明:1区内可达性表现出显著的中心外围递减的圈层空间格局特征;2区外可达性表现出显著的东西分异格局特征;3乌蒙山区综合交通可达性整体水平较低,中心城镇可达性水平相对较好,整体差异不大,可达性水平表现出明显的低均衡性特征。综合交通可达性具体表现出"核心-外围"圈层分异结构特征和东部与西部分异结构特征。建议从跨省区域交通网络合作、快速交通网络大通道、区域交通网络联通率、全域交通运输方式的变革等方面重视跨省山区交通网络建设。
[Abstract]:Based on the basic theory of traffic geography and GIS technology, a spatial barrier accessibility model was constructed in the mountainous regions of Yunnan, Sichuan and Guizhou provinces, and 42 counties (cities, districts) in Wumeng Mountain region across Yunnan, Sichuan and Guizhou provinces were taken as a case study. The results showed that the reachability of area 1 showed a significant decline in the central and peripheral spatial pattern of the circle. The characteristics of the east-west differentiation pattern showed that the overall level of comprehensive traffic accessibility in the Wumeng Mountain area was lower than that in the Wumeng Mountain area, which was characterized by significant east-west differentiation pattern. The accessibility level of central cities and towns is relatively good, but the overall difference is not significant, and the accessibility level shows obvious characteristics of low equilibrium. The comprehensive traffic accessibility shows the characteristics of the "core-periphery" ring structure and the differentiation structure between the east and the west. It is suggested that we should pay attention to the construction of trans-provincial mountain transportation network from the aspects of inter-provincial regional transportation network cooperation, rapid transportation network large channel, regional transportation network connectivity rate, the change of the whole area transportation mode, etc.
