摘　　要：高能耗高污染的水泥生产在增加经济效益的同时也带来了沉重的环境负担,严重影响了水泥行业的可持续发展.将能值理论引入水泥制造工业,综合经济要素、资源要素和环境要素对水泥生产系统进行可持续性评价.以Odum能值分析理论为基础计算若干个能值指标,通过与钢铁工业园及全国综合系统的能值指标相比较,表征水泥企业的运行特征,度量其发展的可持续性.研究结果表明,水泥企业经济发展程度较低下,对环境的依赖程度非常高,其可持续发展水平仅稍好于钢铁工业园.建议通过工业废弃物替代矿物原料、利用余热发电等必要的技术手段,提高水泥生产的生态效率,提升发展的可持续性.High-energy consumption and high-pollution cement production brings about economic benefits as well as heavy burdens on the environment, which has great impact on the sustainable development of cement industry. Emergy theory was introduced into cement industry taking economic factors, resources factors and environmental factors into account to evaluate the sustainability. Based on Odum^s emergy analysis theory accounting several emergy indices, through comparing with the indices of iron and steel eco-industrial park and national synthesized system, the sustainability of cement industryrs operation and development is represented and measured. The results show that cement manufactory is at low degree of economic development and high degree of environmental dependency. The sustainability of cement manufactory is a little better than that of iron and steel eco- industrial park. It is suggested to improve the eco-efficiency and sustainability of cement production by replacing raw materials by industrial wastes, making use of waste heat to generate electricity and SO on.
