激光诱导击穿光谱技术是一种新型的原子光谱分析技术，具有实时快速、多元素同时分析和样品预处理简单等特点，从一出现便受到研究人员的广泛关注，但分析灵敏度差一直是限制该技术发展的重要因素。基于共振激发的激光诱导击穿光谱技术将原子荧光光谱技术和激光诱导击穿光谱技术结合，对目标元素进行选择性激发，可以大幅提高激光诱导击穿光谱技术的分析灵敏度，极大地拓展了L IBS技术在痕量元素检测领域的应用。本文综述了基于共振激发的激光诱导击穿光谱技术的研究进展，介绍了激光诱导等离子体中荧光光谱的产生过程以及基于共振激发的激光诱导击穿光谱技术的基本类型和基础原理，详细分析了烧蚀激光能量、共振激发激光能量和波长、烧蚀激光和共振激发激光之间的延时以及光谱采集门宽对光谱增强效果的影响，阐述了其在冶金、环境监测、同位素检测等领域的应用现状和存在的问题，并对其未来发展前景进行了展望。
