摘　　要：通过分析我国目前煤炭利用的主要方式和存在的问题,分析对比国内外煤炭高效洁净化利用技术,研究高效洁净化利用技术对环境的影响程度,建立了煤炭高效洁净化利用指标体系,给出了评价煤炭高效洁净化利用程度的洁净化度、生态优化度、低碳度的概念并作出了相应的定量判据,最后提出了我国2030年、2050年煤炭高效洁净化利用的有效途径和发展战略。The clean coal utilization strategy which is an important part of energy development strategy of China was presented.The main forms and problems of coal utilization in China were analyzed,and an index system for efficient and clean utilization of coal,including clean degree,eco-friendly degree,and low-carbon degree was developed.Based on the analysis of the structure and quantity of coal consumption in China,the paper gives the index values of 2020,2030,and 2050,respectively.The development strategy of efficient and clean utilization of coal in China is finally proposed for 2011 to 2030 and 2031 to 2050.The results show that： a.By 2030,coal will still play a dominating role in the strategic layout of energy supply in China.With the adjustment of energy structure,the application and innovation of new technologies,coal will be used more cleanly,more environmental friendly,and with less CO2 emissions by 2050.b.The efficient and clean utilization of coal is the strategic direction for sustainable development of energy supply.Low-carbon utilization of high-carbon energy source can be obtained.c.In the next few decades,complete transform from currently extensive coal supply mode into scientific supply which meets the reasonable needs will provide direct support for the efficient utilization of coal.d.Low-carbon utilization of high-carbon energy is in accordance with green development strategy of China.
