The Research On The Eco

Environment and development have become two major topics which people concern all over the world. There is considerable relationship between them. Only the economic, social and natural are harmonious, the development is sustainable. The construction of Eco-city refers to economic, social, demographic, science and technology, resource and environmental factors. It is a complex dynamic open system which temporal and spatial scales are highly integrated. The building of Eco-city is not only for the purpose to provide a good living and working environment for urban residents ,but also to achieve the fair among the same generations and the different generations. Additionally, this new development model has provided an endless driving force, making the whole social healthy, harmonious and to develop orderly. Many cities in China have targeted to develop the eco-cities.Hohhot, the capital of the Inner Mongolia, is in the harsh natural conditions, whose ecological environment is fragile and baffles the economic growth .urban development are facing many difficulties, so the ecological city is the correct choice. This paper examined a large amount of documentations and is on the basis of a field survey. Combining with the analysis of actual condition in Hohhot, I built an in-depth study of ecological city in Hohhot from the perspective of regional studies.First of all, through reading literature, I smooth history of eco-city and outline the concept of eco-city, which are elaborated mainly from urban design perspective, the perspective of the environment, ecosystem perspective and the perspective of ecological engineering. Although eco-city is not the city in traditional sense, it has the general features of normal city .more importantly, it emphasizes urban ecological standards, the pursuit of harmony in urban systems and high efficiency. Eco-city has characteristics: harmony, efficiency, integrity, sustainability and regional. There are concepts, such as urban landscape, garden city, and healthy cities are easily confused with eco-city. Based on the large amount of information, the paper shows the difference and relationship and reveals the scientific nature and superiority of the eco-city.Then I make the deep-seated analysis for international and domestic eco-cities. There are lots of international success cases, such as the Portland City in United States, Copenhagen in Denmark; Stockholm, Madrid, etc.this paper uses the representative and comparable models. Studying these successful models and learning lessons help us expand horizons and find our own development model. The paper includes international ecological model in urban construction and takes the examples of Critical in Brazilian and the eco-city in Japan. And then, I deduce three points. After that, I take Guiyang and Weihai as examples to find ways and experience of the guidelines for eco-cities building in China .according to above cases, we can come to the generalities: every city should choose development mode of their own; eco-city building shouldn't be lopsided.The article goes to the empirical phase - research on the building of eco-city in Hohhot. Firstly, the specific circumstances, including geographical location, economic, historical and other subsystems are analyzed qualitatively in Hohhot, and then the history of development of ecological urban is recalled: in October 1999, Hohhot city proposed building the eco-city and plan to achieve the target within 10 years. There are also problems in urban construction at the same time: urban green space is less, income levels of residents are low, prices are relatively high, and consumption patterns can not meet the needs of the ecosystem.After the qualitative study, sustainable level of Hohhot is researched quantitatively by using the ecological footprint model. Ecological footprint model calculates human's consumption of natural resources and the ecological carrying capacity of natural resources to measure regional sustainable development, Which is combination of empirical research and data research. based on the visit and the Statistical data yearly, through ecological footprint model and the calculation of the ecological carrying capacity model , ecological deficit reaches more than ecological surplus is speculated in Hohhot, which shows the state is not sustainable. This state is not only worse than the average level in Inner Mongolia, but also has gaps with other parts of the city.Part VI is based on the analysis above and combined the successful ecological model at home and abroad and the specific circumstances of Hohhot to reach a new model - eco- forest city. Under the limited human and financial resources, project can be focused on the following specific areas in order to achieve the goal of sustainable development, including the building of the natural ecology, humanities, ecological construction and ecological consumer industries.The last part expatiates the countermeasures of construction of the forest eco-city in Hohhot, which emphasis the predominant system circumstance. Contents are as follows: grasp the meaning and substance of eco-city and be practical and realistic; build the perfect law system; encourage the civic to participate and cultivate civics'ecological consciousness; pay attention to the leadership of the government and layout in advance and evaluate afterwards; build the predominant management system.The contribution mainly embodied in Part three and Part five. Eco-city model are studied at home and abroad in third part .The model eco-city can be classified into the green eco-city, the symbiosis of ecological urban environment, recycling - based eco-city and high-tech oriented ecological coastal city, which have the same objective, but specific focus. Cases indicate that economic development and eco-city construction are not directly related. Many eco-cities building in China summed up the valuable experience, which have guiding significance for other places. The fifth part is data verification. Eco-city construction in Hohhot has been carried out a few years, but the quantitative research and literature related is rare. I note that quantification is effective, so I apply ecological footprint to calculate Hohhot sustainability. Results show per capita ecological deficit of square hectares is 3.106932748 in 2004 in Hohhot, Which is 2.74 times than per capita ecological carrying capacity. Hohhot is in a state of non-sustainable development.
