摘　　要：简要介绍了高光谱遥感的概念及其特点,并阐述了高光谱遥感技术估测牧草地上生物量原理。在阐述植被指数在草地科学领域运用的同时,介绍了植被指数NDVI和RVI的特点,就NDVI和RVI在草地地上生物量估测中的运用做了初步的探讨,并分析了不同草地类型对植被指数及草地地上生物量的影响。其结果表明,不同草地类型中使用的植被指数及估产模型各异。In this paper, it was briefly narrated concept and characteristics of hyperspectral remote sensing technology, and the principle of using hyperspcral remote sensing to estimate forage aboveground biomass. Additional, it was looked back the application of vegetation index in pasture science fields. And it also narrated the characteristics of vegetation index NDVI （ normalized difference vegetation index ） and RVI （ ratio vegetation index）. Finally it was discussed the relationship between vegetation indices and grassland biomass, and analyzed the impact the different natural grassland type affected vegetation indices and grassland aboveground biomass. The results showed different vegetation indices and yield estimation model were used in the different grassland.

关 键 词：高光谱遥感 植被指数 地上生物量 估产模型
