可达性是度量区域交通便捷程度的重要指标。本文首先计算了江苏省长江以北地区交通网络的连结度,然后以苏北运河地区各县(市、区)为研究对象,通过计算其陆路(包括铁路、高速公路、国道、省道)和水路(七级及以上航道)交通网通达度之后,将结果进行地理编码,并进行快速聚类分析。根据聚类所得结果做出通达度专题分析图,并对结果进行了分析。文章的最后,对苏北运河航运未来的发展方向提供了一定的建议。
Reachability is an important indicator of traffic convenience. This paper first calculates the degree of connection of traffic network in the area north of the Yangtze River in Jiangsu Province, and then takes the counties (cities and districts) of the North Jiangsu Canal area as the research object, and calculates the land transport network (including the railway, the expressway, the national highway and the provincial highway) Waterway (seven and above fairway) traffic network accessibility, the results of geocoding, and rapid cluster analysis. Based on the results of clustering, we made a thematic analysis of accessibility and analyzed the results. At the end of the article, some suggestions are given to the future development direction of the North Jiangsu Canal shipping.
