| 摘 要： | 以长江经济带为例,采用耦合协调度模型研究陆路交通可达性与城镇化的耦合协调度空间格局。结果显示：① 城镇化发展大致表现为“东高西低”和“大城市群高边缘城市低”的分布特征,且人口与经济城镇化发展不同步;② 各类陆路交通可达性存在“东中部高,西部低”的分布特征,且高铁可达性区域差异远大于普通铁路和公路;③ 陆路交通综合可达性与城镇化耦合协调度总体较高,由东向西耦合协调度逐渐降低,其中,公路耦合协调度结果与陆路综合交通耦合协调度结果最匹配,高铁和普通铁路对城镇化发展承担跨区域协调作用,高铁作用更明显,公路对城镇化发展影响有限,仅能带动周边区域。

| 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. |
