| 摘 要： | 利用ＮＯＡＡ／ＡＶＨＨＲ数据和地面实测产量值，分析、模拟了鲜草重量和植被指数之间的数理关系，并对草地产量进行了模拟预报。结果表明，采用两种植被指数和七种经验公式所选出的最优预报模型，在地势比较平坦，草地类型变化不大的地区，可以较准确地反映草地产量的变化；但在地形复杂、草地类型变化较大的地区，模型稳定性变差，不适合于草地产量的预报。

| Abstract: | By means of NOAA/AVHHR data and the observed grassland yield,this paper analysed and modeled the arithmetical relationship between the vegetation index and the fresh grassland weight, meanwhile,predicted the grassland yield in Fukang county. The results indicated that the optimum predicted model,selected by two vegetati on index and seven predicted models,could precisely indicate the grassland yield change in the areas of which the topography is flat and the grassland type has little change. But it is unsuitable to predict the regions where the terrain is complicated and the grassland type changes largely because the predicted stability of the model becomes not very well. |
