摘　　要：古气候学是研究地球的过往气候的一门学科,可以预测未来气候变化,解决有关环境、资源等问题。基于激光诱导击穿光谱的元素成像技术可以快速、准确、原位分析复杂多样的大面积古气候样本,获得能够与气候建立联系的元素信息,在气候变化研究中展现出很好的应用前景。首先介绍了基于激光诱导击穿光谱的元素成像技术的基本原理,其次回顾了目前常用的成像系统的仪器配置,包括激光光源、聚焦系统和光谱探测系统等,最后介绍了国内外基于激光诱导击穿光谱元素成像技术分析古气候代理物的典型案例。该研究对基于激光诱导击穿光谱的元素成像技术在古气候研究中的应用有很好的指导作用。Paleoclimatology is a discipline that studies the past climate of the earth,and its purpose is to predict the future climate change,to solve problems related to the environment,resources and so on.Based on laser-induced breakdown spectroscopy(LIBS),the complex and diverse large area paleoclimatology samples can be quickly,accurately and in situ analyzed by the element imaging technology,and the element information that can be linked with the climate can be obtained.LIBS thus has a good application prospect in climate change research.This paper first introduces the basic principles of element imaging technology based on LIBS.Secondly,it reviews the instrument configuration of the currently commonly used imaging system,including laser light source,focusing system and spectral detection system.Finally,typical cases of analyzing paleoclimate agents based on LIBS element imaging technology at home and abroad is introduced.Therefore,this paper has a good guiding role for the application of element imaging technology based on LIBS in paleoclimate research.
