Abstract:

 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 [JP2]them， and then made an identification of noncoordination between urbanization [JP]and ecological environment in [JP2]Jiangsu Province during 1994-2011 The results showed that： [JP](1) the level of urbanization was characterized [JP]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
