摘　　要：近红外光谱技术(Near Infrared Reflectance Spectroscopy,NIRS)具有快速、低成本、无损等优点。目前利用NIRS获取土壤信息已成为国内外学者研究的重点,但是在我国利用NIRS对土壤成分进行定量分析才刚刚起步。本文简要介绍了近红外光谱分析的基本原理、模型的建立及评价,详细论述了该技术在预测土壤有机质及其组分方面的应用,并对NIRS在我国土壤有机质定量研究方面的应用前景进行了展望。As a rapid,inexpensive and non-destructive analytical method,near infrared reflectance spectroscopy（NIRS） is widely used in many fields,including plant age measurement,quality detection of fruit and vegetable.Recently,the application of NIRS in quantitative analysis of soil parameters is emerging,especially in China.In this paper,the authors briefed the principle,methods of model building and evaluating of NIRS,and then reviewed application of NIRS in measuring total soil organic matter（SOM） and SOM components.The application prospect of NIRS technique on SOM analysis in China was also discussed.
