摘　　要：建材行业作为长江中游地区重要发展产业之一,在推动经济发展的同时,也存在资源利用率低、大气污染物排放量大等生态环境问题。工业共生理论为缓解长江中游地区建材行业经济发展与资源消耗、大气污染之间的矛盾提供了新思路。该研究首先分析湖北某工业园区建材行业企业间的物质流动现状,再基于工业共生理论,构建以废弃物资源化、大气污染物减量化为特征,以水泥厂、混凝土厂为核心并涵盖多家不同类型建材生产企业的物质链,最后采用物质流分析和CALPUFF模型对物质链构建后的经济、大气环境效益进行评估。研究结果表明,通过将仅存在企业内部的单一线性物质流动模式改造为企业间多元复合的循环物质流动模式,建材行业的企业间生态关联度提高了33.3%,园区废弃物利用率提高了28.67%,温室气体减排潜力提高了31.50%。同时,CALPUFF模拟结果显示,物质链的改造大幅降低了空气污染物的排放及扩散,带来显著的大气环境效益。The building materials industry is one of the most important developing industries in the middle reaches of the Yangtze River. As the development of the building materials industry promotes local economic growth, it also brings in severe environmental problems such as low resource recycling rate and severe air pollutants. The theory of industrial symbiosis provides a new idea to approach the conflict between economic development, resource consumption, and air pollution of building materials industry in the middle reaches of the Yangtze River. This study first analyzes the current situation of the material flow among enterprises in building materials industry in an integrated industrial park in Hubei Province. Then, based on the theory of industrial symbiosis, it constructs a material chain characterized by waste recycling and reduction of air pollutants, with cement and concrete plants as the dual cores and covering several different types of building materials production enterprises. Finally, material flow analysis and the CALPUFF model are used to evaluate the economic and atmospheric environmental benefits of material chain construction. The results show that by converting the single linear material-flow pattern existed only within enterprises into multiple circulating material-flow pattern among enterprises, the ecological correlation between enterprises in the building materials industry increases by 33.3%, the waste utilization rate in the park is increased by 28.67%, and the greenhouse gas emission reduction is potentially increased by 31.50%. The CALPUFF simulation results also demonstrate that the modification of the material chain dramatically reduces the emission and transport of air pollutants, leading to significant atmospheric benefits.
