中文摘要：

城市化与生态环境是一对互为耦合的时空函数关系式,其间包含多种协调和非协调的耦合状态,如何基于逆向思维和问题诊断的视角构建一座由非协调病理通向协调发展道路的桥梁具有重要的现实指导意义。通过协调与非协调之间的互动关联,构建城市化与生态环境非协调耦合判别函数,并以1994-2010年的江苏省为例,对二者之间的耦合关系演化展开了实证分析。结果表明：（1）城市化水平表征为一条持续上升曲线,而生态环境发展整体水平有较大幅度的提升,但同时表现出明显的阶段性特征;（2）城市化与生态环境的非协调性耦合度在持续下降,但始终停留在磨合非协调性耦合阶段,离实现二者的协调可持续发展还有很长一段时间要走;（3）判别的基本结论表明江苏省城市化在快速推进的进程中,是以牺牲环境为基本代价的,并据此围绕二者之间耦合的作用机制展开了分析。

英文摘要：

Urbanization and ecological environment represent a coupled spatial and temporal function, which contains a variety of coordinated and non-coordinated coupling states. How to develop the reverse thinking and problem diagnosis perspective, to build a bridge to lead the non-coordinating pathology to the coordinated development, has become a key question in the current sustainable development study. This article, based on the interaction between coordination and non-coordination, built an evaluation index of urbanization and ecological environment and a nonconforming coupling discriminate function between them, and then made an identification of non-coordination between urbanization and ecological environment in Jiangsu Province during 1994--2011. The results showed that： （1） the level of urbanization was characterized by a substantial rising curve; while the level of ecological environment showed a significant phase characteristics, but the total level increased a lot; （2） during the study period, the degrees of non-coordination between urbanization and ecological environment in Jiangsu Province continued to decline, but it remained in the third stage of non-coordination, which means it need a long time to achieve the coordinated sustainable development between them; （3） the process of the urbanization in Jiangsu Province from 1994 to 2011 was unreasonable, which took ecological environment as a basic expense. At last, from the perspectives of institutional environment catalysis, socio-economic development drive and natural environmental constraints, this study analyzed its mechanism between urbanization and ecological environment, and thought that, in order to reduce the damage of ecological environment, designing a reasonable institution is very important.
