Exploration Of Eco-city Planning-

The prosperity of modern industrial civilization prompted cities becoming the most important development birthplace of Man, which is the product of human modern civilization progress and development, and the core of the national and regional social development. The acceleration of urbanization of the world inevitably leads to a series of ecological environment destruction. The emergence of eco-city has fundamentally laid the foundation of future urban development pattern. Eco-city, endowed with new concept and connotation, is a product of development of the times. Since the late 1990s, a lot of eco-cities have been built around the world. Many advanced cities in China also try to do it, in which a lot of successful cases contribute to the planning of other cities. The emerging of eco-cities relieves and resolves the endless city problems and provides a kind of good ideas and research subjects.The research on eco-city has become the hotter subject both at home and abroad due to its important significance in city development. Through the systematic analysis of the eco-city status and trends, ecological indicators evaluation, basic theory and practice, and research frontier of eco-city, the paper proposes a new eco-city construction principle.Combined with the actual situation in Dalian, the selection of the Analytic Hierarchy Process (AHP) and the qualitative overall evaluation method are adopted. The ecological index system in Dalian city is studied and analyzed, resulting in: Ecological Composite Index (ECI) is 1.300, a higher degree with first level. The existing problems are analyzed, including the lack of economic structure optimization degrees, the lag of social security system development, the low utilization of energy, the low resource recycling effect and the poor urban air quality. According to specific problems in Dalian ecological city construction, recommendations and countermeasures are put forward. The probable effect factors are also analyzed in order to support Dalian eco-city building.
