摘　　要：基于耦合模型和象限图法,从整体和内部分异2个角度对2000~2012年哈大巨型城市带要素集聚程度与生态环境水平演变及其关系进行分析,结果表明:哈大巨型城市带要素集聚程度呈波动上升的演变特征,生态环境则"先波动上升,后缓慢下降",城市带整体要素集聚程度与生态环境水平间关系趋于协调,产业结构演变、资源消耗水平、经济密度是导致城市带要素集聚程度与生态环境水平协调度提高的主要驱动因子,其中产业结构演变的影响作用更加明显。城市带内部要素集聚的"四城市"格局已经形成,呈现出"核心-边缘"结构,要素集聚程度与生态环境水平可分为高级协调、要素集聚滞后、低级协调、生态环境滞后4种类型。4个区域中心城市要素集聚程度与生态环境水平关系趋向不协调,中心城市周边地区主要向要素集聚滞后型转变,资源型城市和重工业城市要素集聚程度与生态环境水平多表现为低级协调。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 quick- ly 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 struc- ture, resource consumption level, economic density are main elements, which contribute the coordination de- gree 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 be- tween 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 ele- ment agglomeration lagged; resource-dependent and heavy industrial cities present low coordinated.
