Eco-city Construction

Abstract

City is a kind of special artificial ecosystem that is created according to the will of human. Urbanization in china have created unlimited opportunities for the theoretical development and practice of urban ecology, Chinese scholars have achieved important progress in the practice of urban ecological planning and design, especially about ecological security pattern, “anti-planning” theory and practice oriented to ecosystem service and based on ecological aesthetics. They are not only widely used in the city construction in china, but get a high evaluation of the international community. In recent decades, urbanization has become an irreversible and inevitable trend, however, the development of most city depend on high resource consumption and the damage to environment, a series of ecological problems such as declining in air quality, water environment pollution and dramatic increase in the number of waste have been brought about. In the face of growing ecological pressure, constructing eco-city has gradually become the consensus of governments all over the world. Theory of ecological carrying capacity, ecological function zoning, and construction of ecological civilization are the key theory in urban ecological planning and practice in China. In the past twenty years’ theoretical research and practical exploration for eco-city construction, Chinese-featured eco-city development pattern has been formed on the basis of fully absorbing international experience and lessons of eco-city construction and combining with their own practical situation, it played an important role in environmental protection in the process of rapid urban development. But in practice, the related theory still have some problems and insufficiencies, in future practice of eco-city construction, the key theory and technology research need to be strengthened, the connotation of urban ecological construction need to be further improved, so as to keep the virtuous cycle of urban ecosystem, show the pattern of harmonious development of urban construction, economic construction and environmental construction.
