高光谱技术——生态学领域研究的新方法

Hyperspectral Technique:An Opportunity in Ecology

高光谱技术是一种新的地物探测技术,该技术以其敏锐的地物光谱特征探测能力为精准识别地物属性提供了强有力的手段,在生态系统过程与属性研究中具有广阔的应用前景。该文以可见光-近红外光谱分析技术为例概述了高光谱技术的原理、特点与优势,以及高光谱技术分析的流程;总结并归纳了其在土壤、植物生理、农产品品质检测、凋落物分解方面的研究应用,指出高光谱技术与遥感成像技术结合在生态监测研究中的优势;归纳了高光谱技术应用中面临的问题,并希望高光谱技术在生态学领域研究中得到更广泛的应用。

The hyperspectral technique is a robust method that can accurately identify surface features via the high resolution detection of spectral features.It has wide application prospects in the study of ecological processes and properties.Here,we systemically reviewed the implication of the hyperspectral technique in soil,plant physiology,quality detection of agricultural products and litter decomposition based on its principles,characteristics,advantages and analysis processes.Its disadvantages and drawbacks were also discussed to allow for better application in ecology.
