摘　　要：以长三角12个集装箱港口为研究对象,选取2000—2015年各港口的吞吐量数据,采用基尼系数及其分解技术、重心偏移法和半径维数法等对长江三角洲集装箱港口体系的总体极化—离散格局、区域中心—外围格局、港口收敛—发散格局进行综合测度,并运用R/S分析法研判港口体系的空间集疏演化趋势。研究表明:2000—2015年间,长三角集装箱港口体系总体上由极化向离散转型,其中组间差异是港口体系空间分异的主要原因;港口运量集中分布于港口体系的运量重心,但呈现出由中心向外围扩散的态势;多数港口属于向上收敛或向下收敛型港口,对港口体系空间集疏起到均衡化作用;另外,长三角集装箱港口体系在未来的空间疏散化现象和边缘港挑战效应将长期持续下去。With the throughput data of 12 container ports in Yangtze River Delta from 2000 to 2015, this paper measures the spatial distribution pattern of container port system in Yangtze River Delta from the perspective of polarizationdispersion pattern, center-periphery pattern and convergence-divergence pattern, using the method of Gini coefficient and its decomposition technique, gravity displacement and radius dimension. To achieve this aim, this study researches the spatial evolution tendency of port system in Yangtze River Delta using the method of R/S analysis. The main results are summarized as follows： during 2000-2015, the port system is transformed from polarization to dispersion on the whole,and the discrepancy between groups is the main reason for the spatial differentiation; the distribution of port traffic is concentrated in the center of gravity of the port system, but it shows the trend of spreading from the center to the periphery; most ports belong to the upper-convergence or lower-convergence ports, which play a role in balancing the spatial structure of port system. In addition, the space evacuation phenomenon and the challenge of the periphery in container port system in Yangtze River Delta will continue for a long time.
