摘　　要：近三十年来,我国的城镇化进程快速发展,城镇化率由18%提高到51%,形成了一大批城市群,城镇化在促进国民经济增长和改善人们社会生活的同时,也带来了城市生态系统日益恶化,经济社会发展和城镇化初衷逐渐背离,城市的可持续发展受到挑战。基于此,文章对我国城镇化背景和历程进行了梳理,初步分析了城镇化带来的城市生态问题及城市生态系统脆性发生原因,提出了城市生态系统脆性结构及其发生机理,进一步探索如何预防城市生态系统脆性发生并解释未来我国城镇化的发展思路。In the recent thirty years, with the rapid development of urbanization process of China, the urbanization rate increased from 18% to 51%, a large number of city groups were formatted.
