Over the past 30 years, China’s rapid urbanization process has brought along some issues such as excessive consumption of resources and environmental pollution, as well as other phenomena contrary to ecological civilization, and therefore is unsustainable. The core of ecological civilization and urbanization are people. New urbanization and ecological civilization construction have the same target. Considering the feedback mechanism of the four subsystems (resources, environment, economy and population) to urban development, the concept of ecological civilization should be run through the whole course of urbanization development and urban construction in the aspects of economic, political, cultural, social, etc. In addition, the ecological planning and intelligent design should be done in the urban development on the aspects of production, consumption and infrastructure construction, so as to realize the new urbanization development model with the characters of environment-friendly and resource-saving.
