阐述了高光谱遥感在植被研究中经常用到的重要处理方法,评价了近期有关高光谱遥感在植被应用方面的进展,总结了高光谱遥感在草地上各个方面的作用,重点介绍高光谱遥感在草地生物量估算、草地物种识别与分类、生物化学成分估测等方面的应用,并探讨了高光谱草地遥感的前景及发展趋势,随着各种新技术的不断引入,包括数字摄影技术、GPS的引入及各种数据处理方法运用等。利用高光谱遥感进行草原定量分析、动态监测的精度将进一步提高,高光谱遥感将发挥更大的作用。

The application of hyperspectral remote sensing in vegetation research was introduced and the related application progress was reviewed and evaluated in this paper. The application of hyper- spectral remote sensing in grassland, including the biomass estimation, grassland type identification and chemical composition estimation, were reviewed as well. The development trend in this field was discussed. With the introduction and usage of new technologies, such as digital photography and GPS, the hyperspeetral remote sensing will play more important role.
