摘　　要：轻稀土是中国储量丰富的稀土资源,在整个稀土资源的开发应用中占有重要分量。通过介绍中国轻稀土资源的储量及分布特点,可以看出部分轻稀土元素存在“稀土不稀”的现象。在新能源汽车蓬勃发展之际,轻稀土在汽车领域的高端应用面临着前所未有的发展机遇。分别从轻稀土需求量较多的稀土储氢材料和稀土永磁材料方面概述了中国轻稀土资源目前的应用技术水平、存在的问题以及在新能源汽车上的应用现状。最后,梳理出了轻稀土应用的可循环产业链,指出了轻稀土实现高端应用对中国轻稀土资源实现绿色、健康和可持续发展的重要意义。Light rare earth is the most abundant rare earth resource in China,which plays an important role in the development and application of the whole rare earth resource.The reserve and distribution characteristics of light rare earth resources in China is introduced.The paper also objectively points out that some light rare earth elements are not rare.Thriving in the new energy cars,high-end application of light rare earth is faced unprecedented opportunities for development.The consumption of light rare earth in rare earth hydrogen storage material and rare earth permanent magnet materials,the application of light rare earth resources in our country,the existing problems and the application status in new energy vehicles are briefly discussed.Finally,the industrial chain of high-end application of light rare earth is sorted out,and the way to realize high-end application of light rare earth is pointed out,which is of great significance for green,healthy and sustainable development of light rare earth resources in China.
