【摘要】：南方丝绸之路经济带连接“丝绸之路经济带”和“21世纪海上丝绸之路”,是“一带一路”的重要组成部分。它在历史上不同时期先后涉及中国西部10余省、东南亚11国、南亚7国、中东和西亚27个国家和地区。本文从整体性大尺度出发,采用GIS技术和可达性分析方法,结合地学信息图谱思想,地图学及地图制图学理论,开展了以下4个方面的研究:(1)基于地学信息图谱思想、地图学和地图制图学理论及GIS可视化方法绘制了南方丝绸之路经济带时空演变图谱。发现南方丝绸之路及节点城镇早期多沿着河谷地带分布,后期和近现代沿着公路、铁路等交通网络分布;路网空间、结构、节点城镇数量随时间不断扩大、愈加复杂、急剧增加。(2)基于GIS空间统计分析方法描述了南方丝绸之路经济带空间统计特征。节点城镇(空间分布上)具有正的空间自相关,空间上集聚分布的区域对应了路网、节点城镇核密度值高值区,也是南方丝绸之路经济带的核心区。(3)基于GIS和可达性方法计算了南方丝绸之路经济带交通网络可达性。可达性受到交通条件、距离、交通网络密度及分布特征的影响。核心区交通网络可达性值较高,5个时期(原始社会时期、先秦时期、秦汉以来、唐宋以来、新时期)平均出行时间分别为60h,20h,40h,30h,5h;可达性低值区分布在没有交通网络的集聚地或边缘区。(4)综合贸易额、人口和GDP总量、交通成本、距离构建可达性模型,结合GIS技术计算南方丝绸之路经济带中国与其他国家的空间可达性。结果表明:空间可达性与经济总量、人口规模成正比,与距离和交通限制成反比;可达性高值区对应了空间密度核心区,即46个国家中心城市周围,与中国毗邻接壤区,南中国海-马六甲海峡-马来群岛沿岸,孟加拉湾沿岸-印度半岛南端-印度洋沿岸,波斯湾海峡-底格里斯河沿岸,红海海峡-苏伊士运河-地中海沿岸等地。
[Abstract]:The Southern Silk Road Economic Belt connects the Silk Road Economic Belt with the 21st Century Maritime Silk Road, which is an important part of Belt and Road. In different periods of history, it involves more than 10 provinces in western China, 11 countries in Southeast Asia, 7 countries in South Asia, 27 countries and regions in the Middle East and West Asia. Based on the theory of geoscientific information atlas, cartography and cartography, the following four aspects are studied in this paper: (1) based on the idea of geoscience information atlas, the following four aspects are carried out: (1) based on the idea of geoscientific information atlas, this paper adopts GIS technology and reachability analysis method. The theories of cartography and GIS visualization method were used to map the spatiotemporal evolution of the Southern Silk Road Economic Belt. It is found that the southern Silk Road and node towns were distributed along the river valley in the early stage and along the road and railway network in the late and modern times. The number of road network space, structure and node towns is increasing with time. (2) based on the GIS spatial statistical analysis method, the spatial statistical characteristics of the southern Silk Road economic belt are described. Nodal towns (spatial distribution) have positive spatial autocorrelation, the regions of spatial agglomeration and distribution correspond to road network, the high value region of node towns' nuclear density, It is also the core area of the Southern Silk Road Economic Belt. (3) based on the GIS and accessibility method, the accessibility of the Southern Silk Road Economic Belt transportation network is calculated. Accessibility is affected by traffic conditions, distances, traffic network density and distribution characteristics. The average travel time in five periods (primitive society period, pre-Qin period, Qin and Han dynasty, Tang and Song dynasties, new period) was 60 h ~ 20 h ~ 40 h ~ (30) h ~ (-1) ~ 5 h; (4) Comprehensive trade volume, population and total GDP, transportation cost, distance to build reachability model. The spatial accessibility of China and other countries along the Southern Silk Road Economic Belt is calculated with GIS technology. The results show that the spatial accessibility is proportional to the total economic volume, the population scale, and the distance and traffic restriction. The area with high reachability corresponds to the core area of spatial density, that is, around the central cities of 46 countries, bordering China, the South China Sea, the Malacca Strait and the Malay Islands, and the Bay of Bengal, the southern tip of the Indian Peninsula, and the Indian Ocean. Persian Gulf Strait-Tigris River coast, Red Sea Strait-Suez Canal-Mediterranean coast and so on.
