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.

Key words: urban land use efficiency, the coupling relationship and coordination, spatio-temporal evolution, the three provinces of Northeast China
