China’s urbanization undergoes such four stages as construction of productionstyle cities for industrialization from 1949 to 1978, urban system reform from 1979 to 1990, external enlargement and internal rapid reconstruction of the cities from 1991 to 1999 and overall urban and rural development. Currently, China’s urbanization has mainly four problems such as the peasants who lose their land, ecological environment, resources and urban development balance. This paper points out that the new layout of future urbanization should be oriented by deepened urbanization, low carbon ecological cities, associated city group, medium-sized and small cities and so on, and that China should solve the systematic problems of employment, education, medication and housing in the process of urbanization in microscopic viewpoint, reform household register system which divides cities and rural areas for such a long time, solve the problems of resources and environment in middle term, build low carbon cities, promote coordinated development of city group and small cities in macroscopic viewpoint by overall rural and urban development, using big cities to drive the development of small cities, and by building jointly development mechanism of big cities, medium-sized cities and small cities.
