| 摘 要： | 在EOS MODIS资料可见光波段光谱特性的深入分析的基础上，提出了一种完全用MODIS可见光波段监测沙尘信息的技术方法。充分利用MODIS资料可见光范围波段划分细致的特点，构造了不同的光谱特征判别函数作为决策树的分支，最后用决策树法成功地对几次沙尘暴过程进行了沙尘信息遥感监测。结果表明，该方法具有良好的效果和实用性。

| Abstract: | Through analyzing the spectral characteristic of the MODIS visible bands, the methods of monitoring dust storm is putted forward by using MODIS visible bands data. Based on abundant informations of the MODIS visible bands, the distinguishing functions of different spectral features of varions surface information were construct as branches of decision tree. The some dust storm weather processes were timely monitored by using the decision tree. The monitoring results show that the methods are of valuable for practical use. |
