Study On Eco-City Construction And Evaluation Method

With the quickening of the process of urbanization, the increasing of urban population, the decreasing of cultivated land and other sustainable resources and polluting of ecological environment and so on, more and more stress and great challenge are put on the ecological system of the cities.Construction of Eco-city is a valid means that resolves a modern city prob-lems and carry out cities'sustainable development, having become a common cry of mankind, and representing a future development direction of city. This is a re-sult of different countries'effort for "our common future", therefore changing the tradition economic development mode, seeking the sustainable development for the whole world, also a result, that mankind seeking the human & nature's sym-biosis and coordination and a more ideal human's residential environment. So, researching the problems on the construction of eco-city becomes one of the most important tasks of realizing the goal of it. Eco-city construction means taking an eco-city as a compound of'society-economics-nature'system, planning and con-trolling and implementing and managing it by systematic and scientific theory and method. All these demand that we continually strengthen the research on the theories and methodologies of eco-city construction. So it is theoretically and practically significant to explore an effective road of Eco-city construction and to make a rational combination of the social, economic and environmental benefits.This thesis consists of six chapters. Chapter 1 introduces the background of eco-city construction, both domestic and overseas research, development the ob-jective, signification, content and methods of this research. Chapter 2 analyzes the construction of eco-city systematically, sets forth the concepts and the charac-teristics and the standard etc. The structure and functions of urban ecosystem, the mechanism of sustainable development, the connotation and principles and the development model of eco-city construction are systemically studied in this chapter. Briefly speaking, the eco-city is a multi-goal, multi-functional and inte-grated system with complicated structure, and is a sort of human living quarter with high economical efficiency, comfortable surroundings, and communal har-mony. The essence of eco-city is the harmony and pleasantness of the environ- ment, harmony being the epitome of the features of eco-city while pleasantness being the principal guideline in building eco-city. Chapter 3 attempts to establish the theoretical structure for the strategic project of setting up eco-city. On the ba-sis of the idea of eco-city and its theoretical foundation, this chapter studies the system of eco-city construction management, and mainly includes management system, management organization, operation mechanism, management innova-tion, and the digital network system etc. Analysis has been done on the construc-tion of the mechanism of execution for eco-city development in the aspects: mar-ket, administration, legislation and public participation, and the guide measures for eco-city development has been given for technology sustentation in the chap-ter. The planning theories have been studied in the chapter 4. Setting out from the angle of the city-planning course, this research regards ecology as the main line and expands eco-planning's meaning. On the base of research about the urban and rural space's composing, the theory based on the essential functions of city plan-ning, the chapter integrates environment ecology, natural ecology, societal ecol-ogy, economic ecology and landscape ecology. It discusses eco-planning theories and methods from such three aspects as spatial formation, economic development, and social development. Combining theory and practice, it researches the corre-sponding techno-ways about eco-planning, and discusses about the problems forcing businesses into the mode of ecologicalized, which is considered as one of the key issues in the development of eco-city. This chapter not only discusses the essential idea of developing ecological businesses, but also stresses the signifi-cance of an ecological living pattern for the development of ecological business development and then for that of eco-city. Lastly, it researched some policies, which brought eco-planning into effect. Such contents are related to city planning managing mechanism and exterior environment mechanism innovation. In chap-ter 5, the method of combining qualitative with quantitative analysis has been adopted, and advances the contents and methods of comprehensive assessment, at the same time establishes an index system of eco-city comprehensive assessment, then the model that fits the assessment of eco-city construction t is developed. Last the application of Artificial Neural Network (ANN) model is studied in pre-diction of eco-city development, which can lively imitate this system, and the in-dicators involve economy society and environment. At last, in chapter 6, the the- sis advances the contents and the strategies to promote the work of Harbin's eco-city construction. The main aim of this chapter is to establish a theory framework for eco-city construction in Harbin, and therefore establish a basis for further re-search in future.
