摘    要:主要以山东,河南两省为例,探讨了利用NOAA/AVHRR图像资料监测大面积表的几种研究方法,并对每种方法的优缺点进行了评估。结果表明,几种方法结合使用并借助地理信息系统,进行大面积的旱情监测是可行的,另外还进行了利用机载雷达图像监测河北省土壤水分的方法尝试研究,分析表明微波遥感监测土壤水分具有广阔的应用前景,可以利用星载SAR图像资料作进一步的分析研究,从而获取微波监测土壤水分的最佳波段和最佳极化

关 键 词:旱情  监测  微波遥感  GIS

Abstract:In this paper,methods research on monitoring large area drought by using NOAA-AVHRR image data including their advantages and disadvantages were discussed in Shandong and Henan Provinces.The results showed that they were effective ways to monitor drought with the help of GIS.On the other hand,a study on monitoring soil moisture using airborns SAR image data was introduced.The results indicated that microwave remote sensing would be great potential for monitoring soil moisture.So the further research must be done using the SAR image data from satellites.
Keywords:Drought  monitor  GIS  Soil  moisture  Microwave  remote  sensing
