Abstract: Carbon footprint is the total amount of CO2 emissions by particular product or service system in it full life cycle, or, it is the total amount of direct and indirect CO2 emissions by activity principals. There are significant differences of provincial total carbon footprint result from the different energy efficiency, final demand and input-output relationship of intermediate products. Based on the Structure Decomposition Analysis and input-output model, the differences of carbon footprint between Beijing and Tianjin are analyzed in this paper. The results show that the total carbon footprint is higher in Beijing than that in Tianjin. The effect of carbon emission intensity on carbon footprint in Beijing is lower than Tianjin by 0.008 billion tons CO2; according to the complicated relationship between industries in Beijing, there is 0.029 billion tons CO2 more the carbon footprint than Tianjin, The demand scale and structure is higher than Tianjin, So in the factors of final requirements on carbon footprint, the carbon footprint of Beijing is higher than Tianjin by 0.058 billion tons CO2.

Abstract: Ecological civilization city was made up of population, resources, environment, economic compound system, is a multi-function, multi-level and multi-objective evaluation objects. Construction of ecological civilization city is the request of the ages; it is a profound reflection on the industrial revolution, human development model. Ecological city is the result of human ecological value orientation, the inevitable trend in the development of future city. Ecological civilization city will become the ecological civilization construction and the main development direction of modern city and the pursuit of goals in the 21st century. This article begins with the concept and connotation of ecological civilization city, it obtains seven concrete construction of index, they are the ecological environment, ecological economy, ecological livable, ecological philosophy, ecological culture, ecological political, ecological infrastructure and ecological law, and specific construction method is given according to the characteristics of different indicators.

Abstract: Atmospheric concentration of greenhouse gases rising, extreme weather phenomenon happened frequently, those triggered the research and practice of low-carbon economy worldwide. What is the low-carbon economy, how to examine a country have reached a low-carbon economy or not, what the difference among them, and what efforts they made. Unfortunately, those problems have not been a clear answer, and still do not have a comprehensive evaluation index system to comprehensively reflect the connotation and characteristics of the low-carbon economy. Therefore, based on low-carbon economy connotation and using hierarchical analysis method, this paper construct evaluation index system of low-carbon economy and development ability, which include 1 target layer, 5 standard layers and 19 index layers. And then, base on above index system, we also using hierarchical analysis method design a play table for expert, and put play table to 191 experts. According to the analysis results of play table, we assign weight to every indicator. Finally, this paper design evaluation model of low-carbon economy and development ability.

Abstract: Ecological poverty alleviation is a new way of poverty alleviation to make the poverty region realize the sustainable development. It aims to change the ecological environment of poor areas, while, improve the efficiency of the ecosystem service function and the benefit of poverty alleviation. Whats more, improve the effect of rural poverty alleviation fundamentally and realize social sustainable development. The paper studies the urgency and necessity of implementing ecological poverty alleviation in concentrated poverty areas by analysing the obstacle factors of regional ecological poverty alleviation. Then, puts forward a relevant solution that perfect the ecological compensation mechanism, combine the ecological agricultural industrialization with land circulation by science and technology, additionally, increase the financial input and strengthen the countermeasures of environmental protection consciousness.

Abstract: This paper has set an evaluation index system for "two-oriented society", which was divided into four levels. The factor analysis was adopted to find out the public factors of input indexes and output indexes about conserving resources and environment, then the scores of all public factors were calculated, and the construction conditions of our nearly 10 years "two-oriented society" were evaluated by using the data envelopment analysis. The conclusion was that the construction conditions of Chinas "two-oriented society" showed a rising trend which was at the expense of the coordinative development of the subsystems. At last, some suggestions were put forward.

Abstract: The development of low-carbon economy is considered as a top-down economic transformation driven by policy. The realization of low-carbon economy is not simply been technical but policy-making methods need to be conducted in-depth research. This paper delivers a policy influence research method by constructing a regional low-carbon development model based on System Dynamics, and validates this model by comparing the simulation data and the Chinese calendar year statistics. Finally, some policy making suggestions based on the research are provided.

Abstract: The contradiction between traditional resource depletion and social development was acute increasingly in the mining development of Southern Jiangxi. According to limitations of mine resources and needs of social-economical development and environment conservation, the necessity and feasibility to develop circular economy were analyzed, and a few advices were put forward to promote mining sustainable development in Southern Jiangxi, China.

Abstract: First of all, problems and errors of circular economyin coal enterprises are summarized. And then in view of economy and strategicmanagement, the nature of circular economy is analyzed, that is relative diversificationand vertical integration based on marginal reward over marginal cost. Moreover,the solution of flexible development of circular economy is provided, explainedwith “3+3 model”. Finally, the framework of circular economy mode in coalenterprises is constructed with 3 important respects, which are control of nodeflexibility, evaluation of resource reward and risk appraisal of new programs.

Abstract: Low carbon economy provides the direction for the sustainable development of the coal industry, but how to measure low carbon economic development level of the coal enterprise has become social concern. Based on the Xinwen group as an example, the paper constructs level evaluation index system of low carbon economic development about the coal enterprise from the present situation of the development of low carbon economy. Using AHP and fuzzy comprehensive evaluation method measure low carbon development level, and the conclusion is that the Xinwen group's low carbon development level is good.

Abstract: In the development of low-carbon economy, Shaanxi Province in many respects, such as the energy structure, level of social economic development and capital and technology are facing a series of challenges. But, in the meantime, in other respects, such as reductions in carbon emissions space, advantage of backwardness and rich natural resources etc, Shaanxi has the opportunity of developing low-carbon economy. Accordingly, Shaanxi should develop low carbon economy from the following aspects: optimize energy structure, vigorously promote energy conservation, low carbon technology, developing the tertiary industry and playing the advantage of solar and wind energy.
