摘要

摘要:
针对锌冶炼用氧化锌富集物的再生效益进行评估，对推动锌再生资源利用的合理规划，支持环境管理的科学决策具有重要意义。以国内企业的调研结果为依据，建立包括经济效益、资源效益、环境效益和社会效益4个层面影响因素的氧化锌富集物再生综合效益评价指标体系；运用层次分析法（AHP）和基于指标相关性的权重确定方法（CRITIC）对指标进行组合赋权，再对采用黄金分割法划分的标准云进行修正，进而构建基于组合赋权-云模型的综合效益评价模型，并对江西某铅锌金属公司进行实例评价。结果表明：该企业氧化锌富集物再生制锌的综合效益水平较高，一级指标中资源效益水平高，环境、社会和经济效益水平较高，且环境效益和社会效益的评价结果不确定性更大。所得结果兼顾评价过程中的模糊性和随机性，提供了更加全面的锌冶炼用氧化锌富集物再生效益评价信息。

Abstract:
Evaluation of the regeneration benefit of zinc oxide enrichment for zinc smelting is of great significance for promoting rational planning of the utilization of regenerated zinc resources and supporting scientific decision-making of environmental management. Based on the survey results of domestic enterprises, an evaluation index system for the comprehensive benefits of zinc oxide enrichment regeneration was established, considering economic, resource, environmental and social factors, where comprehensive weights were obtained by applying the analytic hierarchy process (AHP) and CRITIC method for weighting, and the standard cloud divided by the golden section method was modified. Then a comprehensive benefit evaluation model based on the combination weighting method and cloud model was constructed. After that, a lead-zinc metal company in Jiangxi Province was used as a case study. The results showed that the comprehensive benefit level of the company's zinc production from zinc oxide enrichment regeneration was at a high level. Regarding the first-level factors, the resource benefit was at the highest level; the environmental, social and economic benefits were at the second high level, and the evaluation results of environmental and social benefits were more uncertain. The fuzziness and randomness were considered in the process of evaluation, which provided more comprehensive evaluation information of the regeneration benefit of zinc oxide enrichment for zinc smelting.
