摘要
利用拓扑学知识对皖南旅游区公路交通网络展开分析。结果显示:区内公路交通网络密度以宣城、池州和黄山3地数值较高;交通网络连接性不断得到完善,连结度β指数由2000年的1.92上升到2008年的2.17;公路交通网络连通度γ指数由2000年的0.69上升到2008年的0.78,区内各节点连通水平较好;公路交通网络回路性α指数由2000年的0.53上升到2008年0.67,目前处于中等水平;公路交通通达度有较大提升,平均径路长由2000年的3.26减少到2008年的2.61,其中马鞍山市、当涂县、池州市和黄山市通达性提高最大,芜湖市、铜陵市、南陵县和泾县提高较小,其他县市居中。分析认为,近10年来皖南旅游区公路交通虽然有了很大发展,但在安徽全省公路交通发展中的优势并不突出,优先发展包括公路在内的交通网络体系是皖南旅游区未来发展的首要条件。
This paper uses topology knowledge to analyze the highway transportation network structure of tourism area in Southern Anhui Province.The results are as follows：In the view of the density of the regional road transport network,the value of highway traffic network density is much higher in Xuancheng City,Chizhou City and Huangshan City.In the view of the value of transport network connectivity,the index β increased from 1.92 in 2000 to 2.17 in 2008.The transport network connectivity in the area has been improved continuously,the index γ in southern Anhui tourist area increased from 0.69 in 2000 to 0.78 in 2008.The region node connectivity levels are good.In the view of the loop of transport network,the index α in the area increased form 0.53 in 2000 to 0.67 in 2008.At present time,the index of the loop transport network in this area is at a medium level.In the view of the average path length,the value increased from 2.36 in 2000 to 2.61 in 2008.The accessibility of road traffic has got a better improvement.In the view of network node,the accessibility of Ma＇anshan City,Dangtu Town,Chizhou City and Huangshan City improved the most,while that of Wuhu City,Tongling City,Nanling Town and Jing Town the least,and that of other cities and towns the mediun.The transport of southern Anhui tourist area has been developed greatly for the past 10 years,but its development has still lagged behind the great development of the whole province,or even the whole country.The key condition of developing the southern Anhui tourist area is to give the first place to development of the transport network.
