摘　　要：为了深入剖析长三角港口群的等级规模分布及演化规律,以货物吞吐量和集装箱吞吐量为衡量港口规模的指标,运用港口首位度和位序-规模法则对长三角地区港口规模分布进行研究。结果表明:长三角地区港口间差距不断缩小,港口等级规模分布由首位分布向位序-规模分布演变;江苏省港口等级规模结构比较松散,高位序港口集聚效应不明显,浙江省港口吞吐量分布则过于集中;长三角港口群规模分布总体上呈分散化发展趋势,未来需要加快推动内河港等小型港口的发展,进一步优化港口体系结构;长三角港口群的货物运输已形成比较稳定且分散的系统,而新兴集装箱港口不断涌现,集装箱运输发展迅速,其等级体系仍在不断变化,长三角集装箱港口的规模分布集聚程度更高。In order to deeply analyze the scale distribution and evolution process of the port group in the Yangtze River Delta,we apply cargo throughput and container throughput as the indicators to measure port scale,and use the port primacy index and the rank-size rule to study the port scale distribution in the Yangtze River Delta.The results show that the gap of ports in the Yangtze River Delta has been narrowing,and the port scale distribution has evolved from the primacy distribution to the rank-size distribution.The port scale structure of Jiangsu Province is relatively loose and the combined effect of high-ranking ports is not obvious,while the distribution of port throughput in Zhejiang Province is too concentrated.The scale distribution of the port group in the Yangtze River Delta is generally decentralized.In the future,it is necessary to accelerate the development of small ports such as inland river port and further optimize the port system structure.The port clusters in the Yangtze River Delta has formed a relatively stable and decentralized cargo transportation system,while container transportation is developing rapidly with new container ports keep emerging.The hierarchical system is still in constant change.The scale distribution of container port in the Yangtze River Delta has a higher degree of concentration.
