色素浓度的动态变化是一系列植物生理特性和过程的诊断指标。本文综述了利用高光谱遥感技术在多种空间尺度上无损、重复地定量颜料的发展技术和分析方法。对高光谱反射率数据的各种特征和变换之间的预测关系的推导进展进行了评价，并对叶和冠层辐射传输模型的作用进行了综述。确定了对不同方法进行更广泛的相互比较以及进一步研究解释冠层尺度数据的战略所需的条件。本文探讨了将研究扩展到除叶绿素以外的更广泛的颜料、测试新出现的高光谱分析方法以及探索高光谱与激光雷达遥感的融合的前景。尽管有这些进一步发展和技术改进的机会，但目前有证据表明，在生态生理、环境、农业和林业科学中的应用范围不断扩大，这突显了植物色素高光谱遥感的日益增长的价值。
The dynamics of pigment concentrations are diagnostic of a range of plant physiological properties and processes. This paper appraises the developing technologies and analytical methods for quantifying pigments non-destructively and repeatedly across a range of spatial scales using hyperspectral remote sensing. Progress in deriving predictive relationships between various characteristics and transforms of hyperspectral reflectance data are evaluated and the roles of leaf and canopy radiative transfer models are reviewed. Requirements are identified for more extensive intercomparisons of different approaches and for further work on the strategies for interpreting canopy scale data. The paper examines the prospects for extending research to the wider range of pigments in addition to chlorophyll, testing emerging methods of hyperspectral analysis and exploring the fusion of hyperspectral and LIDAR remote sensing. In spite of these opportunities for further development and the refinement of techniques, current evidence of an expanding range of applications in the ecophysiological, environmental, agricultural, and forestry sciences highlights the growing value of hyperspectral remote sensing of plant pigments.
