| 摘 要： | 在阐述城市土地利用效益系统耦合协调性内涵及其交互作用机理的基础上,构建综合评价指标体系,运用均方差决策法、耦合协调度模型,对东北三省2003~2015年城市土地利用综合效益及其主成分间耦合协调关系进行测度,并分析其时空演化过程。研究认为：① 城市土地利用综合效益表现出随时间“先升后降”的特征,区内三省间差异明显,中心和门户城市长期处于较高水平。② 城市土地利用经济效益亦存在“先升后降”的时序变化特征,空间上表现为“南高北低”,低值区范围缩减明显;社会效益差异不显著,在南北方向上表现出“凸”字型分布特征;区域生态环境效益整体较高,高值区由集中趋向分散。③ 城市土地利用经济、社会、生态环境效益间耦合协调关系在各时间节点均表现为失调,且以中度失调为主,但中心城市和门户城市的三效益耦合协调关系相对较好,向协调方向发展,哈长与辽中南城市群地区协调性优于其他区域,吉林省与辽宁省东部的部分城市协调关系趋向恶化。④ 城市土地利用效益间关系失调主要受复合因素的作用,经济效益滞后是制约土地利用效益耦合协调关系提升的主因,生态环境效益滞后不是限制土地利用效益耦合协调性提升的主要因素。 |

| Abstract: | On the basis of the exposition to the coupling coordination connotation and interaction mechanism, we build a comprehensive evaluation index system, using the mean square deviation decision, coupling coordination degree model to measure the comprehensive urban land use efficiency in the three provinces of Northeast China, Heilongjiang, Jilin and Liaoning from 2003 to 2015 and analyses its spatio-temporal evolution process. The study found that: 1) The comprehensive efficiency of urban land use show the characteristics of ‘first up, then down’, and there are clearly difference between the three provinces. Besides, the center and the gateway city has long been at a higher level. 2) The change of the urban land utilization economic efficiency are similarity with the comprehensive efficiency, on the space, the low range is reduced obviously; the differences of social efficiency are not significant, but also showed a ‘convex’ word distribution on the space; the overall regional ecological and environmental efficiency is on a higher level, the high value area are changed from concentrated to disperse. 3) The economic, social and ecological environment of the urban land utilization efficiency in the coupling coordination relations between time nodes are characterized by disturbance, and give priority to moderate disorders, but the coupling coordination of different efficiency in center and the gateway city are relatively good and developing in a coordinated direction. Besides, Ha-Chang and the Mid-southern of Liaoning Province is better than that of other regions; 4) The imbalance relationship between urban land use efficiency is mainly affected by complex factors. Lagging of economic benefit is the main reason restricting the improvement of coupling and coordination relation of land use efficiency. The research results show that the current coupling coordination relationship between economic, social and ecological environment efficiency in northeast China is still in the stage of disorder. As a result, It has become the inevitable choice to promote urban land use system coordinated development of economy, society and ecological environmental efficiency in the process of future land use in northeast China. In this process, different types of region should form their own targeted path. For the full lagging region, the most important thing is to improve the economic efficiency of land use through the upgrading of industrial structure, which will increase the social efficiency and ecological efficiency. The social efficiency lagging region should strengthen the intensive use of limited construction land and enhance the level of infrastructure construction to improve urban internal conditions; The economic and social efficiency lagging regions should focus on strengthening the development of continuous industry and the industrial cooperation with the central city. For the other cities, promote clean production and circular economy, strengthen the ability of the central region agglomeration are the important ways to promote urban land use economic benefits. |
