摘　　要：采用动态物质流分析方法,预测了中国乘用车电动化转型中对镨、钕、镝和铽4种稀土资源的需求,并辨识了潜在的供需风险。建议协调推进资源安全与“双碳”战略,深入探索资源减量与替代技术,科学推进自主开采与国际合作,进一步推进中国电动车可持续发展及稀土资源可持续利用。As a core key component of new energy passenger vehicles,permanent magnet motor that add rare earth minerals such as dysprosium and terbium can improve the basic characteristics such as remanence and coercivity.With the acceleration of the comprehensive electrification of vehicles,the prominent contradiction between supply and demand of rare earth minerals is highlighted.A dynamic material flow analysis method is used in this study to predict the demand for praseodymium,neodymium,dysprosium,and terbium resources in China's passenger car electrification transformation.This analysis identifies the supply and demand risks for different rare earth resources.To promote the sustainable development of electric vehicles and sustainable utilization of rare earth resources in China,the study suggests coordinating the promotion of resource security and the dual carbon strategy,exploring resource reduction and alternative technologies,and scientifically promoting independent mining and international cooperation.
