摘　　要：选择耦合协调度模型、剪刀差方法、耦合度模型,分别对沈阳经济区1990—2009年经济系统与环境系统的耦合协调状态、发展速度差异、耦合发展趋势进行了分析.结果表明:研究期间,沈阳经济区经济系统与环境系统的耦合协调状态不断提高.由于经济系统发展水平与环境系统建设水平都呈波动升高趋势,使二者耦合协调度指数由0.42增长至0.89,反映了该区域经济与环境的关系不断改善,较好地实现了二者的协调.经济发展速度的降低与环境建设速度的提高,使二者的剪刀差由0.63°降到0.22°,证明了发展速度有助于协调状态的实现.沈阳经济区经济与环境系统耦合度分布于45°<β<90°的范围,处于共同发展状态,但由于二者演化速率的比值逐渐减小,耦合度逐渐趋近于45°,说明二者关系在逐步走向协调.By using coupling coordinated degree model, scissors difference methods, and coupling degree model, this paper analyzed the coupling coordinated status, development speed difference, and coupling development trend between economic and environmental systems in Shenyang Metropolitan Area in 1990-2009. In the study period, the coupling level of the relations between economic and environmental development was ascending, with the coupling degree increased from 0.42 to 0.89, which reflected the more and more harmonious relationships between economy and environment. The decrease of economic development speed and the increase of environmental construction speed reduced the scissor difference of the two systems from 0.63° to 0.22°, demonstrating the contribution of the economic development speed to the coupling coordinated status. The coupling degree between the economic and environmental systems stretched across in a [45°, 90°] region, which meant that the two systems were in a co-developing status. As the discrepancy between the development speeds of the two systems became smaller, the coupling degree was closer to 45°, and the two systems were becoming better coordinated.
