China is facing ecological revolution now. The basis of the revolution is establishing the ecological consciousness. Different level of ecological consciousness in urban and rural area raised our attention. According to different environment conditions and based on pollution theory, we try to find out the cornerstone of setting ecological consciousness during this changing time. Since China is on the fast urbanization period, environmental awareness change on rural-urban migrants can be this key. This paper focused on which factor(s) have significant effect to ecological consciousness. Urban and Rural residents were interviewed for data collecting, and for deep research, three groups (Urban Residents Group, Rural residents Group and Migrants Group) are split based on responders' migration experience. In this paper, ANOVA analysis and regression analysis are used. Based on pollution-driven theory, two models are given to compare the explanation strengths between within and without theory variables. We found that pollution experience and relative pollute have important effect on eco-consciousness. So Ecological Consciousness is not straight influenced by environment condition, but people think about the deterioration. We considered that, the cornerstone of setting ecological consciousness is recognizing the crisis and disruption of ecological environment.

Abstract We performed a bibliometric analysis of published urbanization research from 1991 to 2009, based on SCI and SSCI database. Our analysis reveals scientific outputs, subject categories and major journals, international collaboration and geographic distribution, and temporal trends in keywords usage in urbanization studies and discusses the relationships between urbanization papers and urbanization rate and offer a substitute demonstration of research advancements, which may be considered as a potential guide for future research. The growth of article outputs has exploded since 1991, along with an increasing collaboration index, references and citations. Environmental sciences, ecology, environmental studies, geography and urban studies were most frequently used subject categories and Landscape and Urban Planning was the most productive journal in urbanization studies. The United States was the largest contributor in global urbanization research, as the USA produced the most independent and collaborative papers. The geographic distribution of urbanization articles overlapped quite well with regions with high economic growth in North America, Europe, and Pacific-Asia. A keywords analysis found the USA and China were "hotspots", confirmed land-use's significant position and revealed keen interest in ecological and environmental issues in urbanization studies. In general, urbanization research was strongly correlated with the urbanization rate although there were different patterns and underlying processes across different countries. This is the first study to quantify global research trends in urbanization. Our study reveals patterns in scientific outputs and academic collaborations and serves as an alternative way of revealing global research trends in urbanization.

Biodiversity protection, conserving and utilizing natural resources to its maximum is the foundation of contemporary social stability and sustainable development of our modern society and is the trend of landscape planning. Reforming the nature based on the basic theory of ecology, the idea of sustainable development, the methods of landscape planning, in order to create a landscape ecological planning pattern which will not cause pollution and secondary pollution and generate landscape ecological function to the upmost.

This study presents three scenarios for Chongqing's energy consumption and related CO2 emissions up to 2020, which includes basic development scenario, macro-policy control development scenario and low carbon development scenario. It explains the crucial technologies for Chongqing city as it leaves a business-as-usual trajectory and embarks on a low carbon pathway. A major finding from the scenario analysis is that low carbon and energy-saving policies can dramatically improve Chongqing's position. Under the low carbon scenario, several suggestions for policy making are proposed. This dynamic low-carbon model would benefit from the allocation of decision-making powers in the areas of regulation, policy-making and planning for low carbon development.

Feature Story August 14, 2012 The year 2011 was a historic moment in the urbanization of China, as its urban population exceeded its rural population for the first time. About 350 million new urban residents are expected to migrate to cities over the coming 20 years. Urban development on such a scale is both a challenge and an opportunity for urban transport. A challenge, as current trends are unsustainable both at local and national level. Locally, the rapid growth in car ownership has enabled greater personal mobility for many but has also brought traffic congestion, accidents, and air pollution. Slow and congested transport systems are beginning to stifle the efficiency of the urban economy. The construction of new roads to accommodate traffic leads to urban sprawl and accelerated traffic growth and hampers the mobility of those who do not own a car. Nationally, excessive conversion of farmland for urban development consumes scarce land resources and impacts the country's ecological systems. Rising fuel consumption also endangers the nation's long-term energy security, while growing emissions from urban transport render the national objectives of CO2 reduction difficult to achieve. But this rapid urbanization also represents an opportunity, as the recognition of urban transport's spillover effects has led to a new policy emphasis on public transport priority and sustainable urban transport development.

The aim of this paper is to understand the sustainability of urban spatial transformation in the process of rapid urbanization, and calls for future research on the demographic and economic dimensions of climate change. Shanghai towards its transformation to a metropolis has experienced vast socioeconomic and ecological change and calls for future research on the impacts of demographic and economic dimensions on climate change. We look at the major questions (1) to explore economic and demographic growth, land use and land-cover changes in the context of rapid economic and city growth, and (2) to analyze how the demography and economic growth have been associated with the local air temperature and vegetation.

Xing [et al.] Paru dans : Procedia Environmental Sciences, Volume 13, 2012, Pages 1143-1148 18th Biennial ISEM Conference on Ecological Modelling for Global Change and Coupled Human and Natural System Abstract It is undoubted that low-carbon city has become a vital development trend for Chinese cities in the new century. Many Chinese cities have been devoted to the upsurge of low-carbon city construction in recent years. Focusing on these problems - What measures has been adopted to construct low-carbon city in China? How is the effect of low-carbon city construction? Are there some issues needing attention in the future - this paper summarizes the situation of low-carbon city development in China and clarifies a few viewpoints that need be paid attention to in the subsequent development. It is expected that the discussion in this paper can help promote the construction of low-carbon city in China.

The simulation of land use change is important in environmental impact assessment and land use planning. We assessed the land use scenarios of China in the next 100 years based on the SMLC (surface modelling of land cover change) model and Dyna-CLUE (dynamic conversion of land use and its effects) model. Three SRES scenarios were evaluated: Global Economy (A1FI): lean government, strong globalization; Continental Markets (A2a): lean government, regional culture and economic development; Regional communities (B2a): much government intervention, regional cultural and economic development. Ten land cover types were simulated, which are cultivated land, woodland, grassland, built-up land, water area, wetland, nival area, desert, bare rock and desertification land. The SMLC model was used to calculate changes in area for each land use types in the future at country level while the spatially explicit land use model Dyna-CLUE was used to simulate land use pattern at 2 km2 resolution based on the country level areas demands for each land cover type. The results show that the cultivated land would decrease in all of the three scenarios, while in the A2a scenario, the cultivated land would decrease with the lowest rate because of the high population growth, high level of market protection and low agricultural efficiency; in the B2a scenario, it would decrease with the highest rate caused by the decreased population numbers and increased crop productivity. The nival area would decrease with the highest rate in the A1FI

This blog contains information and ideas about the interrelationship of religion, nature and modernity with a focus on China. The underlying premises are that religious values and ideas are key resources for constructing a sustainable future for the human species, and that nowhere on the planet is this more important than China. China is the world's largest country by population, the second largest economy in real GDP terms, and the largest emitter of greenhouse gases.

Full Text available. As some of the most rapidly urbanizing places in the world, China's cities have a unique relationship with global climate change. The economies found in Chinese cities are extremely resource and energy intensive; as a result, they produce significant levels of greenhouse gas (GHG) emissions. This article provides comprehensive and detailed emissions inventories for Shanghai, Beijing, and Tianjin, which were found to be responsible for 12.8, 10.7, and 11.9 tonnes of carbon dioxide equivalent per capita (t CO2-eq/capita), respectively, in 2006. The majority of emissions were from electricity production, heating and industrial fuel use, and ground transportation. The prevalence of coal in the energy supply mix (including up to 98% in Tianjin) was a fundamental cause of high energy emissions. Non-energy emissions from industrial processes were also significant, including emissions from cement and steel production. The GHG inventories for Shanghai, Beijing, and Tianjin point to sectors requiring the most attention in terms of low-carbon growth. Compared to ten other global cities, Chinese cities are among the highest per capita emitters, alluding to the important challenge China faces of reducing emissions while improving the quality of life for urban residents. Accordingly, this article concludes with a discussion of the opportunities and issues concerning low-carbon growth in China, including the potential for renewable energy and the difficulties associated with emissions relocation and policy adoption.
