摘　　要：长三角港口一体化是实现区域一体化发展的必然要求.以长三角27个港口为研究对象,通过熵权-TOPSIS法分析了2010年、2015年和2020年长三角港口一体化融入水平.在此基础上,运用引力模型计算港口间的引力值,研究长三角港口一体化空间联系强度和空间联系特征,并通过空间自相关进行检验.研究结果表明:(1)长三角港口群一体化发展程度总体偏低,且发展不均衡,港口两极化特征较为明显.(2)2010年、2015年和2020年港口空间网络结构特征比较相似,均呈现出各港口之间空间联系强度不均的现象.(3)以上海为核心,江苏、浙江为两翼的长三角港口群格局初步显现.(4)长三角港口一体化水平呈现全局正向空间自相关性.The integration of ports in the Yangtze River Delta is an inevitable requirement for achieving regional integrated development.Based on the data of 27 ports in the Yangtze River Delta,the integration level of ports in the Yangtze River Delta in 2010,2015 and 2020 were analyzed by means of entropy weight TOPSIS method.Then,the gravity values of ports were calculated using the gravitational model,with which the strength and characteristics of the spatial connection of the port integration in the Yangtze River Delta were studied,and the statistical results were also tested through spatial autocorrelation.The research results show that:(1)the overall level of integrated development of the Yangtze River Delta port group is relatively low,and the development is uneven with obvious polarization characteristics of ports;(2)the spatial network structure characteristics of ports in 2010,2015,and 2020 are relatively similar,showing an uneven spatial connection strength among ports;(3)the pattern of the Yangtze River Delta port cluster is emerging preliminarily,with Shanghai as the core and Jiangsu and Zhejiang as the two wings;(4)the integration level of ports in the Yangtze River Delta presents a global positive spatial autocorrelation.
