| 摘 要： | 本文论述了内蒙古锡林郭勒草原植被的光谱反射特征，分析了各波段反射率与不同植被牧草产量的相关关系，利用6种比值植被指标和正交指标拟建立产草量的估算模式，并进行了精度检验，确认：比值指标G与ND以及二维正交指标(PVI)可以成功地用以估测牧场产草量，这种估测方法最大误差为10%左右。

| Abstract: | This paper describes the spectral reflectance characteristics of herbaceous vegetation of grassland of Xilin Gol, Inner Mongolia and analyzes the correlation between reflectance of different band and yield of grassland. Some models for grassland yield estimation have been made using six different kinds of ratio-indexes or perpendicular indexes of vegetation. The accuracy of every model has been tested. It was found that G. ND and PVI may successfully be used for yield estimation of grassland with error less than 10%. |
