中文摘要：

城市化与生态环境耦合受到人类活动高强度干扰，要实现耦合的协调发展与脆弱性的减少需要一定内外力的强力支撑。在阐述城『订化与生态环境耦合脆弱性与协调性概念、特征的基础上，提出城市化与生态环境耦合的协调性与脆弱性是在自然条件与孕灾环境、人口素质与城市文明、产业升级与技术进步、制度创新与管理科学、系统自身的恢复力等多种机制的共同作用下发展的。通过挖掘城市化与生态环境耦合的脆弱性与协调性之间的的宏观作用机制，促进城市化与生态环境的良性互动，为提高城市与区域可持续发展能力提供科学参考。

英文摘要：

The 21 st century is the century of the urbanization. With the rapid progress of urbanization in China, the city development is facing the problem of the severe resources and environmental expansion. Vulnerability problems during the urban development become more serious. Urban sustainable development is the objective and basis of improvement the level of the urbanization. Obvious vulnerable stages exist in coupling system of the urban-ecological environment. Therefore, it seems more important and urgent to carry out the research on the coordination and vulnerability between regional urban and eco-environment. Interaction of the urbaniza- tion and ecological environment is always the hot issue in academia, and there have been many great achieve- ments at present. But it is still need to further explore and discuss the interactive mechanisms for the coordina- tion and vulnerability between regional urban and eco-environment. To realize the coordinated development of the system and vulnerability reduction requires a certain amount of internal and external forces. Starting from the connotation of the coordination and vulnerability of the coupling system of urban and ecological environ- ment, this paper discusses the characteristics of coordination and vulnerability. It elaborates that development of the urban -- ecological environmental coordinated system depends on all kinds of interactive mechanisms such as natural condition and disaster-pregnant environment, the quality of the population and urban civiliza- tion, upgrading of industrial structure and technological progress, institutional innovation and management sci- ences, the resilience of urban-ecological systems. For high level of development between Regional Urban and Eco-environment, this study focuses on effects on the coordination and vulnerability of urban-ecological sys- tems by various mechanisms, so as to provide a scientific reference for solving urban and regional sustainable development.
