Coal is an essential fossil fuel in China; however, coal mining and its utilization are being under the increasing pressure from ecological and environmental protection. Therefore, the consulting project "Technical Revolution in Ecological and Efficient Coal Mining and Utilization & Intelligence and Diverse Coordination of Coal-based Energy System," initiated by Chinese Academy of Engineering, puts forward three stages(3.0, 4.0 and 5.0) of China's coal industry development strategy. Aimed at "reduced staff,ultra-low ecological damage, and emission level near to natural gas," breakthroughs should be achieved in the following three key technologies during the China Coal Industry 3.0 stage(2016–2025): including intelligent coal mining, ecological mining, ultra-low emission and environmental protection. This paper focuses on the development trends of the China Coal Industry 3.0 and its support for China Coal Industry 4.0 and 5.0 is analyzed and prospected as well, which may offer technical assistance and strategy orientation for realizing the transformation from traditional coal energy to clean energy. 展开更多

Since the beginning of the 1990s, the market, as a whole, has become calm and stable without any major changes, though it has never evaded occasional rises and fails. The pattern of demand on the market has been generally set and clear, and has begun to grow steadily. In view of the present situation, two major categories of vehicles—office-use and business or service use cars and trucks—have long been in demand on the market, almost dominat- 展开更多

China's first wave of economic globalization is characterized by its full utilization of foreign advanced, especially innovative, production factors in the domestic market to develop its innovation economy. China's participation in global economy can be described as fully utilizing domestic low-end production factors through foreign markets. This type of participation has been overdone. As China aims to engage in a second wave of economic globalization, the focus is to implement an in-depth globalization strategy under the condition of expanding domestic demands, namely and to develop the global economy based on domestic demands, The purpose is to achieve an economic rebalance with the world and help China out of its overcapacity predicament in weaker global economic climates. Moreover, it will bring China a chance to introduce foreign advanced factors to accelerate growth and develop innovation economy by turning economic crisis in the West into opportunities. 展开更多

In this article, the starting points of disciplines in physical geography in recent years in China are discussed. With the coupling of systems set as the research object, and sustainable development as the ultimate goal, the upgrade of physical geography can be deconstructed into three steps: deepen physical geography from the perspective of pattern-process coupling, improve the focus of physical geography from ecosystem processes to ecosystem services, and increase the understanding of the physical geography ‘pattern, process, service, sustainability' research cascade. The incorporation of human activities into physical geographic processes is essential to conduct integrated analysis on physical and human factors at different scales. The development of ecosystem service models that couple supply-demand and sustainable development are of great importance to bridge the role of ecosystem services between the natural environment and human well-being. Moreover, human-land systems and sustainable development have become the core areas and frontiers of integrated physical geography and even geography in general. China faces the great strategic demand of constructing an ecological civilization in a new era, and the development of the disciplines of physical geography should give full access to the advantages of intersecting and comprehensive disciplines, focus on the human-land system patterns,processes, and services in key research areas, and provide disciplinary support for regional, national, and global sustainable development. 展开更多

Coal-based olefin(CTO)industry as a complement of traditional petrochemical industry plays vital role in China’s national economic development.However,high CO2 emission in CTO industry is one of the fatal problems to hinder its development.In this work,the carbon emission and mitigation potentials by different reduction pathways are evaluated.The economic cost is analyzed and compared as well.According to the industry development plan,the carbon emissions from China’s CTO industry will attain 189.43 million ton C02(MtC02)and 314.11 MtC02 in 2020 and 2030,respectively.With the advanced technology level,the maximal carbon mitigation potential could be attained to 15.3%and 21.9%in 2020 and 2030.If the other optional mitigation ways are combined together,the carbon emission could further reduce to some extent.In general,the order of mitigation potential is followed as:feedstock alteration by natural gas>C02 hydrogenation with renewable electricity applied>CCS technology.The mitigation cost analysis indicates that on the basis of 2015 situation,the economic penalty for feedstock alteration is the lowest,ranged between 186 and 451 CNY/tCO2,and the cost from CCS technology is ranged between 404 and 562 CNY/tC02,which is acceptable if the C02 enhanced oil recovery and carbon tax are considered.However,for the C02 hydrogenation technology,the cost is extremely high and there is almost no application possibility at present. 展开更多

As the world seeks to increase ambition rapidly to limit global warming to 1.5℃,joint leadership from the world's largest greenhouse gas(GHG)emitters-the United States(U.S.)and China-will be critical to deliver significant emissions reductions from their own countries as well as to catalyze increased international action.After a period of uncertainty in international climate policy,these countries now both have current leadership that supports ambitious climate action.In this context,a feasible,high-impact,and potentially globally catalytic agreement by the U.S.and China to transition away from coal to clean energy would be a major contribution toward this global effort.We undertake a plant-by-plant assessment in the power sector to identify practical coal retirement pathways for each country that are in line with national priorities and the global 1.5℃ target.Our plant-by-plant analysis shows that the 1.5℃-compatible pathways may result in an average retirement age of 47 years for the U.S.coal plants and 22 years for Chinese coal plants,raising important questions of how to compare broader economic,employment,and social impacts.We also demonstrate that such pathways would also lead to significant emissions reductions,lowering overall global energy-related CO_(2) emissions by about 9%in 2030 relative to 2020.A catalytic effect from the possibility of other countries taking compatible actions is estimated to reduce global emissions by 5.1 Gt CO_(2) in 2030 and by 10.1 Gt CO_(2) in 2045. 展开更多
