Abstract: As typical cities of natural resources exploitation and processing, to make less reliant to natural resources and to regain more Sustainable development power are important issues and pressing tasks for resource-based cities in China. Based on the theory of ecological civilization and sustainable development, this study formulated a coupling coordinative model of tourism-regional economy-ecological environment system, and made a comparison with the coupling relationship among the tourism-regional economy-ecological environment system using 2005-2010 statistics data of three typical cities in Shanxi province by entropy method, which reaches the following conclusions that: It found widespread coupling interaction in the compound system of tourism-regional economy-ecological environment in these three cities; Differences in the aspects of tourist market, geographical location, industrial structure, tourism resources, urbanization process and climatic conditions are the keys to form the coupling relationship; Evaluation on the coupling coordinative degree provides a useful reference for sustainable development of tourism industry in future.

Abstract: With the development of society, the ecological risks continue to produce; ecological risk management is becoming urgent. This paper uses the literature research methods, focusing on the origin of ecological risks, the arising of ecological risk management, the ecological risk assessment model, and the relationship between ecological risk assessment and ecological risk management. Based on research at home and abroad, the paper proposes shortcomings of current research and three areas for further study in the future.

Abstract: This paper is a first step towards articulating a Chinese version of ecological civilization construction (short for ECC). Three major intellectual sources of ecological civilization are identified and the constraints from resources and environment on economic development are emphasized. The concept framework of ECC contains four aspects: the subjects, the objects, the means and the scope. The subjects have five main types: the governments, the entrepreneurs, the families, the NGOs and other mixed ones. The objects involve in various type of ecosystems.The means can be used by education, plan, institution, technology and fund. The scope is stratified five spatial levels: the earth, the nations, the regions, the prefectures, and the communities. Moreover, four paths of ECC are highlighted: resources conservation and saving, environmental protection and improvement, ecological protection and restoration and territorial development and protection.

Abstract: As a large agricultural country, agricultural economic development determines the development of the national economy, and the logistics of agricultural products but restricts agricultural economic development, China's economic development is incompatible with the rural economy, largely agricultural logistics relationship enough disorders due. In this paper, according to the anti-agricultural own characteristics, the condition of the rural economy, the situation of logistics development, management system and development like logistics, be unbalanced urban and rural development and other factors put forward five agricultural logistics development model of sustainable development, and the corresponding development mechanism.

Abstract: Taking the construction industry of Beijing as an example, we, first, accounted the energy consumption (EC) and carbon emission (CE) in 1990-2012. Then, we used the Partial Least Squares (PLS) method to analyze the drivers of the CE. It was found the EC and the CE of Beijings construction industry in 1990 was 8.1 PJ and 0.99 Mt, respectively. They grew up to 30.6 PJ and 4.52 Mt in 2012. The increasing number was 22.5 PJ and 3.53 Mt with an average annual growth rate of 6.23% and 7.15%. The sources of CE were mainly arising from electricity, diesel, gasoline and raw coal. The driver's size of GDP per capita (A) was bigger than population (P). The 1% increase of A or P would make the CE increase 1.758% or 0.105%, respectively. The classical hypothesis of Environmental Kuznet's curve did exist in the CE of Beijing's construction industry. The urbanization rate increased 1%, to some extent, would make the CE decrease 0.421%. The improvement of scientific study itself cannot make the CE decrease. Only when the gotten achievements were transformed into the concrete technology and used in real life, the CE might decrease. So, it was necessary to speed up the new-type urbanization strategies, the development pattern's upgrade and transformation of economy and to continue to carry out national relevant policies on controlling population growth.

Abstract: Transport sector is one of the main sources of anthropogenic greenhouse gases (GHG) emissions. Comprehensive countermeasures are needed in cities to mitigate transport GHG emissions. After reviewing green traffic measures that implemented by Shanghai since bidding for Expo 2010, this paper analyzes the achievement that Shanghai has made in carbon mitigation. The results showed that travel demand management and the constrcution public transportation infrastructure promoted by the event played a vital role in promoting mode shift to form public transport oriented traffic system. Carbon emission intensity of Shanghais urban transport declined steadily from 1.66 kg/trip to 1.55 kg/trip. The CO₂ reduction attributable to mode shifts amounted to 4.99 million tons. It demonstrated that Shanghai Expo has promoted the city in carbon emission reduction through public transport improvement, new energy vehicles innovation, car growth restriction measures and green commuting initiate.

Abstract: Based on the decoupling elasticity model, an analysis is carried out on decoupling relationships between GDP and indicators of resource consumptions and pollutant emissions in Tianjin Economic-Technological Development Area (TEDA). Decoupling elastic coefficients (DECs) of GDP and energy consumption & water usage for nine years (2003-2011) along with the counterparts between GDP and emissions of COD & SO₂ for six years (2006-2010), are calculated respectively. The results are as follows: first, the overall trends between development of GDP and intensity of resource consumptions and pollutant emissions per unit of GDP turn out to be almost perfect decoupling relationships. Second, the DECs of GDP and total energy consumption (TEC), along with weak or better decoupling in 6 of 7 years, displays in good condition from 2005 to 2011 and the ones of GDP and total water usage (TWU) improves a lot, compared to the period of 2004-2007, with a more favorable form of strong or weak decoupling during the period of 2008-2011. Third, strong (40%) or weak (60%) decoupling are witnessed among all the DECs between GDP and COD & SO₂ for five years from 2006 to 2010. It is concluded that construction of eco-industrial park, the main practice of industrial ecology and theory of circular economy, accompanied with circulating fluidized transformation, is powerful driving force for TEDA to realize decoupling relationships between economic growth and environmental pressures and can contribute to achievement of decoupling at bigger level, country or regions.

Abstract: Lack of energy, fire wood use, and deforestation problem are the main issues in Cambodia. In rural area, small biogasification plant project has been successfully conducted. However, it was not applied in urban area such as Phnom Penh city. This study is focused on the household cooking fuel in urban area and aims to find the alternative cooking fuel to wood in Phnom Penh city. With literature reviews, field survey and interviews, we reviewed small biogasification, central biogas plant, and solid refuse fuel as an applicable technology for supplying cooking fuel. We considered the procurement of raw materials, land use, odor problem, operation and maintenance difficulty, and health impact in using indoors. Consequently, solid refuse fuel from bagasse has the potential to supply alternative cooking fuel. Further researches on stakeholder interview and business potential are necessary. Through literature reviews and field survey, it was found there are many failure cases. It is the most necessary to reflect the regions characteristics and the local experts opinions for applying waste-to-energy technology successfully in developing countries.

Abstract: Building a resource-conserving and environment-friendly industrial system not only conforms to the external demand of the international economic environment changes, but also meets the internal needs of the domestic economic transformation and the adjustment of economic growth pattern. It is also an inevitable requirement to realize two-oriented society in Hunan province. This paper expound the necessity of constructing two-oriented industry system from the respects of relations between different fields and the development trend, and explore the constructing ideas of two-oriented industrial system in Hunan province.

Abstract: This explanatory research explores the relationship among environmental uncertainty, knowledge transfers mechanisms, dynamic capability, and competitive advantage.
