随着“T”战略实施,长江开发向纵深推进,沿江港口物流得到迅速发展.安徽长江沿岸主要有马鞍山、芜湖、铜陵、池州和安庆5个港口,随着安徽沿江经济带的建设,以上5港的物流也得到迅速发展.把长江安徽段的港口群作为一个体系,运用主成分分析法定量刻画该体系内各港口物流发展综合实力水平,在此基础上,运用场强理论,通过计算相邻港口物流的断裂点位置探讨了该港口体系港口物流发展的空间竞争格局;并探讨了影响港口物流发展及竞争格局变动的成因机制;最后定性阐述了该港口体系港口物流发展及空间格局的演化趋势.

英文摘要：

With the ＂T＂ strategy being carried on, port-logistics along the Yangtze River have made great progress. There are 5 ports along the Yangtze River in Anhui province. As a separated port system, there are more competition than cooperation during them. In this paper , 15 indexes are put forward to reflect the synthetic competition of port-logistics and it apply the principal component analysis to the synthetic competition of the 5 ports using spss software. Further more, breaking point theory is used to analysis the spatial competition among the 5 ports. Finally, mechanism of the situation change and the trend of competition are discussed.
