| 摘 要： | 不同的草地群落，其反射光谱曲线差异显著，草地植被盖度对光谱反射有显著影响，在５５０ｎｍ波段，随着植被盖度增加，其反射率相应提高，在６５０ｎｍ波段，与之相反，盖度增加，光谱反射率下降；在近红外波段，光谱反射率的增加与植被盖度增长同步，植物群落的季相对反射光谱表现出与盖度相似的影响，在遥感图像上一定有响应。

| Abstract: | This paper showed that the spectral reflectance of vegetatio ncover were not only influenced by theherbage growing,but also by its community seasonal aspect in alpine meadow. There was significant differ-ence among herb,shrub and herb-shrub communities to spectral inflection(Ri).The results will be appre-ciated on forecasting above biomass of alpine meadow. |
