摘要
为深入了解港口体系的发展特点,进一步完善港口建设,对东亚集装箱港口空间格局的演化过程进行探究.运用加权标准差椭圆分析方法,从重心分布、展布范围、分布形状和方向等多个角度刻画了东亚集装箱港口体系的空间分布特征.研究结果表明:东亚集装箱港口体系的空间格局总体呈现不断向北移动且空间缩小的趋势.中国沿海港口不断拉动整个东亚集装箱港口体系的发展,尽管这种拉动作用在2012年之后有所减弱.中国沿海港口经历了21世纪初10年的快速发展,在很大程度上改变了东亚港口空间格局的分布.
East Asia is one of the most important container shipping markets in the world, however, it is facing lots of new challenges under the complex economic and trade situation. With the development of regional economic integration, in order to research the development characteristics of port system so as to improve the port construction, this paper analyzed the evolution of spatial distribution of East Asian container port system. By using the weighted standard deviational ellipse, this paper visualized the spatial pattern of East Asian container port system from the features of gravity center, ellipse range and shape as well as rotation angle. The results show that the spatial gravity center is moving northward with the trend of spatial shrinking;China’s coastal ports continuously promote the development of the entire East Asian container port system, although such effect have weakened since 2012. China’s coastal ports had experienced rapid development in the early ten years of the 21 st century, which have greatly affected the spatial distribution of East Asian ports.
