The utilization of heavy metal-organic polluted cultivated land caused by the e-waste dismantling industry was affected by multi-dimensional factors. Thus a comprehensive evaluation of these multi-dimensional impacts was necessary for the technical selection and solution of cultivated land utilization. This study attempted to conduct a total benefit simulation analysis on the redevelopment of polluted cultivated land, which was of great significance to decision-making. With a systematic framework designed including the casual relations between components, a system dynamics model was constructed to simulate the technological, economic, and ecological benefits of different polluted cultivated land-used modes, along with which a questionnaire was designed to investigate and analyze the associated social effects. Based on these, the total benefits of the land-use mode were evaluated and optimized within the framework of the “technological-economic-ecological-social” evaluation system. This study included microscale, mesoscale, and macroscale, with multi-dimensional and complex influencing factors, and had advanced research value. The results of the system dynamics model simulation showed that remediation plants played a decisive role in pollutants removal. The flower industry had the highest net present value, but its ecological performance was poor. The overall analysis showed that the scenario of utilization after remediation had the highest performance score, which was attributed to high pollutant removal, low cost, and high carbon sink. This study was meaningful for providing research ideas of comprehensive benefits of polluted cultivated land utilization and also helpful for decision-making. This paper also provided research ideas for other industries such as contaminated site remediation and sewage sludge treatment.

整体视角下电子垃圾拆解行业污染耕地利用整体绩效研究


电子垃圾拆解行业造成的重金属有机污染耕地利用受到多维因素影响。因此，对于耕地利用的技术选择和解决方案，需要对这些多维度的影响进行综合评价。本研究尝试对污染耕地再开发进行总体效益模拟分析，对决策具有重要意义。设计了包含各组成部分之间因果关系的系统框架，构建了系统动力学模型，模拟了不同污染耕地利用方式的技术、经济和生态效益，并设计了调查问卷，对相关耕地利用方式进行调查分析。社会影响。在此基础上，在“技术-经济-生态-社会”评价体系的框架下，对土地利用方式的总效益进行评价和优化。该研究涵盖微观、介观和宏观尺度，影响因素多维度、复杂，具有先进的研究价值。系统动力学模型模拟结果表明，修复厂对污染物去除起到决定性作用。花卉产业净现值最高，但生态绩效较差。总体分析表明，修复后利用场景的绩效得分最高，这归因于污染物去除率高、成本低、碳汇高。本研究为污染耕地利用综合效益提供研究思路具有重要意义，也有助于决策。 本文也为污染场地修复、污水污泥处理等其他行业提供了研究思路。
