摘要: 对陆地植被的生物物理参数和生物化学参数进行反演,对夫琅禾费暗线中的叶绿素荧光信号进行提取是植被高光谱遥感的三项基本任务。鉴于叶绿素荧光与光合作用存在密切的联系,叶绿素荧光参数和稳态荧光光谱特征在植物健康状况的评价,环境胁迫因子的早期检测应用中表现出很大潜力,围绕叶绿素荧光遥感的研究快速发展起来。本文结合国内外最新的研究进展对稳态荧光的光谱特征及其产生机理;日光诱导叶绿素荧光信号的检测方法;遥感探测器的类型及工作原理;叶绿素荧光的建模与仿真现状进行了综述;也对叶绿素荧光在非生物胁迫子早期检测、植物病害监测与病情评估领域中的应用进行了综述;对叶绿素荧光遥感研究工作的重点作了展望。

Abstract: Remote sensing of biophysical parameter, biochemical parameter and chlorophyll fluorescence are the three basic missions of the Terrestrial vegetation remote sensing investigation. Extensive research focuses on remote sensing of chlorophyll fluorescence for its sensitivity to the environmental stress and its potential to detect the stress earlier. This paper reviewed the spectrum characteristics of chlorophyll fluorescence, its generating mechanism and its detection methods. The type and working principle of the detector which detect the fluorescence signal in the Fraunhofer lines and the radiative transfer model that includes the flow of the signal was reviewed. When concerning its application, the detection of the environmental stress, the monitoring and assessment of pests was also reviewed. Finally, the future development trends and the prospects of remote sensing of solar-induced chlorophyll fluorescence was discussed.
