中文摘要：

关于港口竞合关系,以往研究思路主要采取理论方法架构或博弈策略,未能深入探讨港口竞合状况。生态学的生态位理论有效地研究了生态系统中物种成长、种间关系和群落演变等问题。根据生态位理论,分析港口生态位的特点及发展规律,提出了港口生态位维度指标体系,仿生化研究港口竞合关系。借助生态位态势、生态位重叠和生态位宽度理论模型,计算港口群内各港口生态位大小和生态位重叠度,并按照生态位扩充、协同发展以及错位分离等策略为各港口选择恰当的竞合方式提供参考,以调整港口竞合关系,促进港口间协调共生。

英文摘要：

Concerning the problem of competition and cooperation relationships of ports, traditional research mainly uses theoretical model architecture or the game strategy and fails in the in-depth analysis of the situation of competition and cooperation relationship of ports. Ecological niche theory effectively studies species growth, relationship between species and community development in the ecological system. According to the ecological niche theory, we analyze the characteristics of port niche and the law of development and build the factor dimension index system of the port ecological niche to carry out the bionic research of competition and cooperation relationship of ports. Based on the theory of niche trend, niche breadth and niche overlap, we calculate the port niche. Using the competitive strategy of niche expansion, co-evolution and dislocation separation, we provide reference for improving the competition and cooperation relationship of ports and achieve collaborative symbiosis between ports.
