Abstract:

Taking the Yangtze River economic zone as an example, the article studies the geographic pattern and coupling-coordination degree between urbanization and land transportation accessibility by using the coupling-coordination model. The results show that: 1) There are significant spatial differences in the development of urbanization, showing the distribution of ‘east high west low’ and ‘urban groups high edge city low’, and the development of population urbanization is synchronous with that of economic urbanization; 2) The accessibility of each land transportations shows the distribution of ‘east high west low’, and the regional difference of high-speed railway accessibility is far greater than the ordinary railway and highway accessibility; 3) The coordination degree between urbanization and transportation accessibility is high generally, decreasing gradually from east to west, and the coordination degree between economic urbanization and transportation accessibility is higher than that between population urbanization and transportation accessibility; What's more, The coordination degree between urbanization and highway accessibility best matches that between urbanization and overall land transportation accessibility. At the same time, high-speed railway and ordinary railway play a role of cross-regional coordination in the development of urbanization, and the effect of high-speed rail is more obvious. What’s more, the impact of highway on the development of urbanization is limited, only driving the surrounding cities development.

Key words: urbanization, land transportation, accessibility, coupling-coordination, the Yangtze River economic zone
