| 摘 要： | 本文阐述了如何利用ＮＯＡＡ资料进行草地监测和产草量估计，在对不同时象的植被指数景象进行纠正的配准后，可叠加得到平均植被指数影象ＡＶＩ。使用聚类分析和数字地面高程模型，可将纠正的平均植被指数影象ＡＲＶＩ制成草地产量等级图。依据草地产量等级图，可对阜康县的１０个不同的草地产量级及其总产量给出准确的估计。

| Abstract: | This paper described using the NOAA data for grassland monitor and yield estimation. After rectifica-tion and registration, the average vegetation index image of different time was extracted. The ARVI(Average Registration Vegetation Index) image was classified into grassland yield map using sorne clusteringand digital terrain model. According to the grassiand claseification yield map, each yield of ten types and to-tal yield of grassland in Fukang county was got accurately. |
