Abstract:

Based on the coupling model and the quadrant diagram method, the element agglomeration degree and ecological environment evolution and their relationship were analyzed from the perspective of the overall and internal in Haerbin-Dalian giant urban belt. The results showed that: 1) The element agglomeration degree is ‘firstly decreased, and then increased’, while the ecological environment is ‘first increased quickly and then dropped slowly’, the relationship between the degree of element agglomeration and the level of the ecological environment become more harmonious. Further analysis found that the evolution of industrial structure, resource consumption level, economic density are main elements, which contribute the coordination degree to higher, and the industrial structure evolution is most remarkable. 2) Within internal elements of urban agglomeration, ‘four cities’ pattern has been formed, present a ‘core-edge’ structure. The relationship between the degree of internal element agglomeration and the level of the ecological environment can be divided into four kinds, which are highly coordinated, element agglomeration lagged, low coordinated and ecological environment lagged. 3) In 2000-2012, the relationship between the degree of element agglomeration and the level of the ecological environment of different cities are in continuous evolution, and the center cities main transformed into ecological environment lagged; the surrounding areas of center cities transformed into element agglomeration lagged; resource-dependent and heavy industrial cities present low coordinated.

Key words: the Harbin-dalian Giant Urban Belt, element concentration degree, the ecological environment level, coordination, spatial pattern
