中文摘要：

在＂一带一路＂战略背景下,推动长江经济带发展是中国一项重大区域发展战略,全面把握其城镇化发展规律对于统筹谋划整个区域经济发展具有重要意义。选取2000-2013年长江经济带城镇常住人口、城镇建成区面积、二三产业增加值作为城镇化扩张指标,通过构建耦合协调模型,对其上中下游地区的人口城镇化、空间城镇化、产业城镇化耦合协调时空演化格局进行系统研究。研究表明：在时间维度上,长江经济带各地区城镇化耦合度整体呈上升趋势,但地区间耦合协调性差异特征依然存在,其上游城镇化耦合协调度波动最剧烈。长江经济带各地区＂人口-空间＂城镇化耦合协调度普遍滞后于＂空间-产业＂城镇化耦合协调度,空间城镇化快于人口城镇化过程,人口城镇化、空间城镇化、产业城镇化的协调性有待优化。在空间维度上,长江经济带各地区的＂人口-产业＂城镇化、＂人口-空间＂城镇化和＂空间-产业＂城镇化耦合协调性存在空间分异现象,总体呈东高西低态势。

英文摘要：

In the strategic context of ＇One Belt and One Road＇, the research on the urbanization of Yangtze River economic belt, one of the most important economic strategic support regions of China, is extremely meaningful. This paper selected urban resident population, urban built-up area and the gross of secondary and tertiary industries during 2000–2013 years as urbanization expansion index, to systematically analyze population urbanization, spatial urbanization and industrialization urbanization temporal evolution pattern of coordinated coupling of upper middle and lower reaches by constructing coupling coordination model. According to the studies： in the time dimension, the regional urbanization degree of coupling Yangtze River economic belt was on an overall upward trend, there still exist differences in regional coordination coupling,while the most volatile is the upstream coupling coordination degree of urbanization. ＇Population – space＇coupling coordination degrees of urbanization in Yangtze River Economic Belt regions generally lags behind the＇Space –industry＇urbanization coupled coordination. At the same time, spatial urbanization process of urbanization is faster than population. Meanwhile, population urbanization, spatial urbanization and industrialization urbanization coordination need to be optimized. In the spatial dimension, there exists spatial variation phenomenon among ＇population – industry＇,＇population – Space＇ urbanization and ＇space – industry＇urbanization of coupled coordination in the regions of Yangtze River Economic Belt. We can see the whole trend is from east to west and the worst area of the coupling coordination is the upstream region in Yangtze River Economic Belt.
