| Eco-city conies into being in the ecological civilization era and is an accepted mode of future city . Presently urban plan focalizes on eco-city construction. On the background of eco-city's development trends and disputation, the thesis firstly reviews the research on the pertinent field . From the urban spatial development of eco-city , summarizes the urban spatial development pattern of traditional city and analyzes eco-city spatial development pattern . Then probes into the deep mechanism of it.In part three According to the situation of our country and the characteristics of eco-city, puts forwards that the pattern of our country's urban spatial development and takes some measures to facilitate it. In part four the thesis conceives a new kind of city pattern- miniplexion city and has a preliminary study on it.The main ideas and conclusions of the thesis are as follows:(1) Eco-city, as the fruit of ecological civilization era , is a new spatial organism form and composes of eco-city eco-town and eco-village in spatial category . In which everything is harmonious, symbiosis shows between human and human , human and nature, city and village.(2) Eco-city's spatial development should be centralized, three-dimensional. All kinds of function space should integrate and be high efficiency. Urban spatial form evolves from core-edge pattern to equipoise development . City scale becomes in miniature and has multi-core structure.(3) Eco-city's spatial development should attach importance to both intension and extension . The deep mechanism is ecological civilization and social ecologism .(4)The pattern of our country's urban spatial development is "centralized-clearance-landscape city ".(5) Has a tentative research on Miniplexion City and puts forward that the pattern of miniplexion city is solid fractal city , the structure of it is three-seven proportion . has an analysis about its spatial position and efficiency.
