摘　　要：以环渤海地区17个港口城市为研究单元,基于生态位理论构建港口城市群生态位评价体系,测算2003-2020年各港口城市的生态位态势、生态位重叠度、生态位适宜度及进化动量,揭示环渤海港口城市群的时空演化特征。结果表明:①环渤海港口城市群生态位格局仍以天津、青岛和大连为核心,但大连的发展态势趋弱,中等生态位水平的港口城市逐渐增强;山东省港口城市呈现出更强的发展动能,而辽宁省港口城市则趋于弱势。②环渤海港口城市群内部竞争较大,但有所缓和,多数中等生态位的港口城市由于发展同质化而导致生态位重叠度较高。③环渤海港口城市群整体生态位适宜度呈下降趋势,进化动量仍较高,说明整个港口城市群的共生进程仍有较大潜能。最后针对不同港口城市制定基于生态位的共生策略,包括生态位扩张、生态位错位和生态位协调,为环渤海港口城市群的演化和共生提供可行路径。In order to scientifically analyze the spatial pattern evolution of port urban agglomerations in the Bohai Rim,this paper takes 17 port cities in the Bohai Rim as research units,constructs an ecological niche evaluation system of port urban agglomera-tions based on ecological niche theory.Then the ecological niche situation,ecological niche overlap,ecological niche suitability and evolutionary momentum of each port city from 2003 to 2020 are calculated to reveal the spatiotemporal evolution character-istics of port urban agglomerations in the Bohai Rim.The results are shown as follows.O Tianjin,Qingdao and Dalian are still the core cities in the ecological niche pattern of port urban agglomerations in the Bohai Rim.However,the development of Dalian tends to weaken,and the port cities with moderate ecological niche levels are gradually increasing.The port cities in Shandong Province have shown more positive development momentum,while the port cities development in Liaoning Province is weak rel-atively.The internal competition of port urban agglomerations in the Bohai Rim is significant,but it is relieving gradually.Most port cities with moderate ecological niche levels have a high degree of niche overlap due to homogenization of develop-ment.③Themean valueof ecological nichesuitability of port urban agglomerationsin theBohai Rimisdecreasing,whilethe evolutionary momentum is high,so this indicates that the symbiotic process of the port urban agglomerations still has great po-tential.Finally,the symbiosis strategies based on ecological niche are formulated for various types of port cities,including eco-logical niche expansion,ecological niche dislocation and ecological niche coordination,thus providing feasible paths for the evolu-tion and symbiosis of the port urban agglomerations in the Bohai Rim.
