| 摘 要： | MODIS传感器具有较高的时间分辨率、光谱分辨率以及适中的空间分辨率,其数据产品被广泛应用于大范围、长时期、动态的干旱监测.针对江西省农业种植以水稻为主的特点,借鉴已有遥感监测模型,选用2000~2008年MODIS数据产品及相关旱情资料进行分析,建立了适合江西省的遥感旱情监测模型,并用2003年江西干旱的实例验证此模型.结果显示,该模型能较好地用于大范围的旱情定性监测.

| Abstract: | MODIS sensor has a high time resolution,spectral resolution and moderate spatial resolution,its data products are widely used in large-scale,long time,dynamic drought monitoring.In this paper,drought monitoring model of remote sensing suitable for Jiangxi Province has been built and verified in 2003,based on rice-based farming to the characteristics,drawing on existing remote sensing monitoring model,as well as choose 2000-2008 drought MODIS data products and related data analysis.The results showed that this model can be used to a qualitative drought monitoring of wide range. |
