Study On Evaluation Of Sustainable ECO-City

With the rapid development of urbanization, ecological environmental problem is of wide concern in the community due to potential detrimental effects on human health, including:atmospheric pollution, noise pollution, light pollution and water pollution.’There is an urgent need for strategies to settle the problems of the relationship between humanity and nature. The ecological movement committed to sustainable development of humanity and nature.has been widely carried out all over the world. Ecological city will most probably be the best pattern of human life style Sustainable development of ecological city is an ideal development pattern characterized as healthy, efficient and civilized, to construct society, environment and economics.Based on the concept and connotation of ecological city. And the reference theory and principle of the system of sustainable development of ecological city at home and abroad to create, Aiming at the problem of ecosystem health assessment of environmental quality, establishing the eco-city system security model. The model set pressure, state and response of three types of indicators to reflect the regional ecological security degree. In addition to the city economic and environmental coordinated development, coordination evaluation system of City Economic and ecological environment. The city’s comprehensive economic strength mainly from the city development level, industrial structure, economic vitality and economic efficiency 4 aspects;mainly from the water environment carrying capacity, ecological carrying capacity of city environment and atmosphere environment bearing capacity in 3 aspects and other environmental bearing capacity to be inspected.Consideration in the past"China Eco-well-of f index in 2013"in "ten urban ecological environment of public satisfaction list" on its efforts and contributions of Yi Xing city made ecological ranked first, becoming China’s most ecologically appropriate home city, but also marks another Chinese Yi Xing become small cities to create a model eco-city. Therefore, this paper select mode Yi Xing City, a decade (2003-2012) as the study of changes in the scale of the eco-city of Yi Xing city conducted a detailed assessment of sustainable development. The following conclusions:(1) Ecosystem security situation in Yi Xing city divided into three stages,0.4 0.6,0.6-0.8,0.8-1,the first stage during 2003 to 2007, are warning stage (III grade), the existence of this stage is mainly the problem is also irrational economic structure, between 2003 and 2007 production growth concentrated in the major products of fine chemical industry, textile and garment industry, metallurgical industry, high-polluting industries, and because of environmental governance is relatively backward, resulting in more secure Yi Xing ecosystem warning situation.The second phase of 2007 to 2010, the ecological system security increased year by year, a gradual transition from warning status (III grade) to a more secure state (IV grade), eco-city overall functionality has been greatly improved. Yi Xing modernization from the overall situation, adhere to the people-oriented, governing for the people, the rapid development of new goals established to create a national ecological city. With the adjustment of industrial structure and energy saving steadily. Beginning in 2007, Yi Xing City, carried out the paper-making enterprises integrated pollution control, in accordance with uniform standards regulation promulgated by the provincial government, more than three years, the city’s various departments to optimize the development environment unswervingly take the road of increasing environmental protection and ecological construction, and build a more rational industrial structure system, maturing green infrastructure system, strictly regulate the environmental regulatory system, strong and effective organizational security system. Energy efficiency, large-scale industrial enterprises million increase in value of energy consumption is declining. Reducing emissions, the total SO2 emissions and COD emissions declining significantly improved the quality of the environment, the performance of the ecological safety of urban systems increasing every year.During 2010 to 2012, and gradually rose from being a relatively safe state (IV grade) to a safe level (V level). After entering the 2010 changes in ecosystems safety of the city in a slow rise in the state. Ecological city construction has made certain achievements. To 2012, the city has built a Dingshu Zhen, Zhangzhu Town Gaocheng Town, Tian Yi modern tourist resorts and other agricultural technology demonstration park and the West bank town acres of nursery stock base model, Yang Zhen ZTE agricultural technology demonstration park.(2) Since 2003, Yi Xing City, the economic and ecological environment in the city has been in a state of harmonious development, in 2003 and 2004 experienced a middle class environment coordinated development lagged, at this stage the main problem lies in the unreasonable economic structure also focus in the fine chemical industry, textile and garment industry, metallurgical industry, high-polluting industries, and because of environmental governance is relatively backward, resulting in Yi Xing City Intermediate coordinated development environment retarded.During 2005 to 2009 experienced a well-coordinated class environment retarded. Experienced a good coordinated development environment retarded, began to strike a balance between development marks Yi Xing economic development and environmental protection. At this stage the process, through the implementation of pollutant emission control, and vigorously promote clean energy and cleaner production audit and other measures that achieve a balance between ecological protection and economic development.During 2010 to 2012 experienced a high-quality coordinated development of economic retarded. A few years ago by the environmental retarded, Yi Xing gradually strengthened its focus on environmental quality. Adhere to transition to cleaner energy structure, the evolution of high-end industrial structure, economic structure to a low-carbon development. Yi Xing makes a beautiful environment and economic development. At the same time, it should be noted that, in promoting eco-city of Yi Xing City, in the process, through continuous improvement of environmental quality, in turn, promote the sound and rapid economic development in Yi Xing,achieving optimized to improve the investment environment and urban competitiveness.
