全球水泥的温室气体排放约占人类活动排放的5％，其中中国的水泥产量就占到世界总量的50％，连续25年居世界第一位，2010年中国水泥总产量达到18．8亿I。水泥行业是我国排放和耗能的大户，其产业特点是总体产量高。企业平均规模小、技术水平低和产品结构落后，因而，水泥行业节能减排行动是我国应对气候变化的重要措施和基本内容，也是实现我国水泥工业可持续发展的重要保证。本文通过大量的实地调研和数据收集，在识别了18种水泥行业节能减排的典型技术基础上，以日产5000t的生产线作为基准．通过边际减排成本的测算。定量分析了我国水泥行业节能减排技术的减排潜力和成本，并最终得到这些技术的边际减排成本曲线。按照减排成本由低到高的排序，主要的减排技术分为能源利用效率、替代能源、混合水泥和CCS技术。最后通过分析我国水泥行业节能减排的技术现状及相关的政策障碍。给出了相应的应对措施和政策建议。

Cement sector emission occupies 5% of the world emissions caused by human activities. Especially, China cement production accounted for 50% of the world＇ s output, which ranked the first for consecutive 25 years. The total production in 2010 was 1. 882 billion tons. Cement sector characterized with high production, small-scale enterprises, low technology development level and poor product structure, is one of the bigger energy consumers and emitters in China. Therefore, energy saving and emission reduction in cement sector are not only the essential measure and basic content for coping with climate change, but also ensures the sustainable development. Plenty of basic research, including spot investigation and data collection, was carried out in this paper. After the identification of 18 different kinds of energy saving technology and emission reduction, a baseline as daily 5 0013 tons of a production line was set in this paper. The mitigation potential and mitigation cost are quantitatively analyzed by estimating the marginal abatement costs. Hence, the marginal abatement cost curve of energy-saving and emission reduction technology was obtained. With the abatement costs ranking from low to high, the key emission reduction technology can be concluded as energy substitution, energy efficiency, cement mixing and CCS technology. According to the status of domestic energy-saving technology as well as support policies, we finally proposed relevant measures and policy suggestions.
