| 摘 要： | 以中分辨率的MODIS数据作为遥感影像源,运用蓝藻水华在蓝波段、红波段和近红外波段的光谱特征,使用假彩色合成法（RGB：6-2-1）和归一化植被指数法对滇池的蓝藻水华进行遥感监测。通过星地同步试验,证明了该两种方法的正确性。其中假彩色合成法通过色彩差异表现蓝藻水华,具有视觉效果较好的优点,归一化植被指数法则以数值大小的方式区别水华浓度,该方法建立反演模型后可用于定量研究。

| Abstract: | On the basis of the MODIS remote sensing images,the bluealga bloom over the Dianchi Lake was monitored by the pseudocolor composition(RGB: 6-2-1) and the normalized vegetation index methods,according to the spectral features in the blue,red,and near-infrared wavebands.Through the satellite-ground synchronization experiments,the accuracies of the two methods are verified.The pseudocolor composition method uses color difference to display bluealga bloom,which has better visual effect,while the normalization v... |
