Study On Building Eco-City Based On Sustainable Development

Currently the ecological movement for the goal of harmony between the human being and nature is launched vigorously and permeated in many ways throughout the world. The focus of city building has changed from the pure beautiful natural environment to the all-round sustainable development of urban ecosystem. Eco-city, with the feature of health, efficiency and civilization, is the ideal model of urban sustainable development all over the world and directs city development in the future. Sustainable development eco-city has become human's common demand. However, there are no normative method and directions for eco-city building. Therefore we combine demonstration analysis with academic, put forward the model of eco-city based on sustainable development and deeply study the methods of building sustainable development eco-city based on the successful experience. This paper is set up on the foundation of the project of building sustainable development eco-city in Harbin which is done during the author's study work of PHD.This paper details out analysis of the present situation of research and application of urban sustainable development and eco-city. It points out the main results and shortage and states the reason why building eco-city based on sustainable development. Secondly, introduce the concept of sustainable development eco-city originally including urban ecology and urban sustainable development. Based on these basic theories, expound the concept of sustainable development city and analyze its aim,building principle and necessity. Then by diagnosing the limitation of traditional city development model study the total structure of sustainable development eco-city according to the feature, structure of urban ecological system and the focus on people of sustainable development. It puts forward the detailed structure of the four subsystems which are social eco-subsystem, economic eco-subsystem, natural eco-subsystem and infrastructure eco-subsystem and gives a detailed research of each subsystem's main content. It defines the function and circulation of sustainable development eco-city system. The spatial framework of sustainable development eco-city is put forward and the rules and conditions of the spatial framework are discussed.The mechanism of sustainable development eco-city such as information-responding mechanism, balancing mechanism, development mechanism and driven mechanism is discussed detail.The basic principle of establishing the evaluation indicator system is introduced.
