摘  要:
采用1992~1994 年牧草产量资料、NOAA/AVHRR 资料分析了北疆主要天然草地牧草产量与卫星植被指数的变化特征。结果表明,牧草产量和卫星植被指数都存在周年变化,用卫星植被指数可以较好地反映牧草产量的年际变化和不同类型天然草地的牧草产量差异,对草甸草地和草原草地的监测效果比对荒漠草地监测效果好。

摘  要:
The production of natural grassland and vegetation indices in the northern Xinjiang Uygur autonomous region during 1992~1994 were compared by using field sampling and NOAA/AVHRR data. It was shown that both practical yield and vegetation indices had a annual variation. The satellite vegetation indices could reflect most of practical information on annual dynamic of forage yield and yield difference among different grassland types. It had better monitoring effect on meadow or steppe than did on desert.
