摘要: 随着经济的快速发展,资源紧缺与环境污染问题日益成为影响社会可持续发展的瓶颈因素。循环经济的理念,就是旨在建设资源节约型和环境友好型的社会。它提出:"废物"是"放错了地方的资源",废物再生利用能促进社会的可持续发展。因此,工业固体废物资源化利用途径的优选,对提高废物综合利用率、节约资源以及减少环境污染,均具有重要的社会意义和经济意义。本文依据层次分析法原理,从经济指标、技术指标和环境指标3个影响因素建立递阶层次结构模型,通过建立动态的工业固体废物资源化优化E-T-E模型、构造判断矩阵、权重计算及一致性检验,把一系列因素进行了定性和半定量化处理,最终可实现废物资源化途径优化的决策,以此为政府部门和环境管理者提供决策参考。Abstract: With the rapid economic development, the problem of resource scarcity and environment pollution has increasingly become the bottleneck of affecting the society sustainable development. The circular economy concept has been constructed to build a resource-saving and environment-friendly society. It suggested that "waste" is "misplaced resources", waste recycling can promote the sustainable development of society. Thus, optimal selection of the resource utilization approaches for industrial solid waste is beneficial to improve the proportion of waste reutilization, economize resources and protect environment. In this paper, the Analytic Hierarchy Process has been employed to select best available measures for waste utilization. Combined with the indexes of economy, technology and environment, the related factors were processed qualitatively and semi-quantitatively through constructing the hierarchical structure E-T-E model of the dynamic optimized industrial solid waste resource, establishing judgment matrix, calculating weight, and testing consistency. In consequences, the decision-making analysis and evaluation on optimum schemes for industrial solid waste utilization approach is realized. The results summarized from abvoe-mentioned assessment method could be referred by government and environmental policies makers.
