稀土元素物质流分析研究进展

 通过文献计量分析，梳理了全球、国家和地区尺度的150余个稀土元素物质流研究案例，发现已有研究涉及物质流分析的多个侧面，但存在基础数据不完备、量化模型不完善、与行业发展需求尚不适应等问题。因此建议：（1）夯实稀土物质流分析研究数据基础，整合稀土不同元素的资源与环境数据，建设稀土行业的大数据平台；（2）延伸稀土物质流分析的研究边界，将原生与再生两种资源、国内与国外2个市场纳入稀土物质流分析体系，模拟稀土全元素、分部门的中长期发展需求；（3）拓展物质流分析方法在稀土产业可持续发展研究中的应用，开展稀土分元素的环境流、贸易流、价值流及供应链风险研究，为稀土产业安全高质量发展提供研究支撑。

Material flow analysis of rare earth elements: A comprehensive review

Rare earth (RE) resources become increasingly critical for emerging and low-carbon technologies. With the rapid development of the global pattern of the rare earth production, consumption and trade, the basic significance of the studies of the flow of the rare earth materials is increasingly recognized at home and abroad in promoting the security of the RE resource supply and the sustainable development of the RE industry, with a great number of papers on the material flow analysis (MFA) focusing on the rare earth elements. This paper firstly reviews the related literature on the origin and the evolution of the REMFA, followed by an in-depth analysis of the limitations of the essential data, the quantitative model and the demand orientation. The following suggestions are made:(1) integrating the data on the RE resource and environment and developing a data platform for the rare earth industry; (2) developing a rare earth quantitative model including a supply-side module consisting of the domestic and foreign virgin and recycled minerals as well as a demand-side module coupling with the industrial revolution and resource; (3) enriching the researches embodying the environmental flow, the value stream and the trade flow of the rare earth elements, to support the high-quality development of the rare earth industry in China.
