Abstract
介绍了利用NOAA/AVHRR资料进行云南大面积干旱监测的方法和业务流程,讨论了干旱指标、面积估算方法、作物干旱识别、产品制作等关键问题,并对1999年春季的曲靖市监测结果作了详细分析。结果表明,在云南利用卫星遥感技术对大范围干旱的面积、程度、空间分布等动态变化监测是可行的。
The method and operational flow of monitoring large-scale drought in Yunnan by using NOAA/AVHRR data are presented. Meanwhile key problems, such as index of distinguishing drought, method of area estimation, identification of crop drought and derivative of image product, were discussed. According to detailed analysis on monitoring product in the spring of 1999 in Qujing region,it was proved that using satellite Remote Sensing technique to monitor area, degree and allocation of large-scale drought is available in Yunnan.
