UNESCO has put forward explicitly the concept of the eco-city in the "Man and the Biosphere Program (MBA)" for the first time. Over the past 30 years and more, all the countries in the world have established the eco-city as the goal of urban development. In the practice, some regions of China have also put forward the eco-city construction proposals; however, due to divergence of understanding of the eco-city theories and incorrect knowledge of the actual local conditions, there have been some misunderstandings in eco-city construction, resulting in the so-called “pseudo–ecology”. This essay is started from study of the basic theories of the eco-city. Based on analysis of the current conditions and problems, it probes into methods and measures of eco-city construction in China, with a view to promote the Chinese cities’ ecological development and eco-city construction.
