摘要
高光谱技术具有光谱分辨率高的优势,在林业、农业、生态、环境等众多领域发挥着重要作用。本文对高光谱技术在植被特征监测中的应用进行了总结,主要涉及植被指数研究、物理生化参数反演、树种识别、生物量估算等内容;同时,以无人机高光谱影像为数据源,对植被指数、特征参数、树种识别等方面进行了案例分析,以期为植被高光谱数据的应用提供参考与借鉴。
Hyperspectral technology has the advantage of high spectral resolution and plays a vital role in many f elds,such as forestry,agriculture,ecology and environment.In this paper,the applications of hyperspectral technology in vegetation feature monitoring are summarized,mainly involving vegetation index research,physical and biochemical parameters inversion,tree species identif cation,biomass estimation,etc.Finally,taking the UAV hyperspectral image as the data source,this paper makes a case analysis of vegetation index,characteristic parameters,tree species identif cation,and so on.Hope the above contents would provide a reference for the application of vegetation hyperspectral data.
