摘要
应用ＮＯＡＡ／ＡＶＨＲＲ遥感资料对阿拉善地区的６个荒漠类草地进行了生长季内的动态监测。结果表明，应用ＮＯＡＡ／ＡＶＨＲＲ遥感资料对阿拉善荒漠进行动态监测是可行的而且是必要的；提出了以“面”取样，“面”与“面”样本区配的建模方式，克服了以往建模方法中样本间“点”对“点”不能很好匹配的缺点。
The research results showed that it was feasible and necessaruy using NOAA/AVHRR data to monitor the Alahshan desert grassland.In order to eliminate the errors of ground point against point(Pixel),the linear equation of estimating yield was built by area against area.The method of area against area derived from point against point was true in theory and feasible in practice.
