近红外光谱技术(NIRS)在草地生态学研究中的应用

Applications of Near Infrared Reflectance Spectroscopy Technique (NIRS) to Grassland Ecology Research

近红外光谱技术(NIRS)是一种快速、高效、无损的现代检测技术,已经在许多领域广泛应用。文章阐述了NIRS应用于草地生态学研究的意义,介绍了NIRS用于测定牧草营养成分、矿物质、土壤养分含量,分析了牧草混合物的组成、动物对所采食牧草的反应、牧草病虫害抗性等一些复杂特性,以及进行生化标记、同位素鉴别研究。综合这些研究可以看出,NIRS能够作为一种整体研究工具应用于草地生态学的许多研究领域中,可以检测各种常规化学成分、分析草地生态系统的各种动态指标和系统运行的多项整体特性。希望通过本文的总结分析,推动NIRS在中国草地生态学研究中的应用,加速该领域研究手段的现代化。

The technology of near infrared reflectance spectroscopy （NIRS） have been widely used in many research areas, owing to its rapidness, high efficiency, low cost and no pollution. The present paper mainly illustrates the significance of the applications of NIRS to grassland ecology research, and explains some innovative implications of near infrared reflectance spectroscopy in the determination of a variety of forage nutrients, minerals, and the components of soil, prediction of the composition of forage mixtures, animal performance, grass resistance of diseases and insect pests and other complex ecological characters, and doing research on biochemical markers, isotope discrimination and so on. By synthesizing these applications properly, it is concluded that NIRS could be used as a holistic tool in grassland ecology research to determine the chemical components ,and analyze the complex dynamic character of grassland ecosystem and the total specialty of the system running. According to this paper, the authors also hope to promote the application conditions of NIRS in the grassland ecology research in China, and accelerate the modernization of research measures in this area.
