摘　　要：通过遥感技术获取了太湖地物的遥感影像,根据地物的光谱特征提取湖泊植被和水体信息,通过传感器定标和几何校正对信息进行预处理,在分析信息波段、光谱值、及NDVI特征的基础上建立决策树,对信息进行分类,提取太湖水生植被的信息。The remote sensing image of landmark in Taihu Lake was obtained with remote sensing technology. According to the spectral characteristics of landmark, the information of lake vegetation and water was extracted, and the information was pretreated through calibration with sensors and geometric correction. On the base of analysis on wave bands, spectrum value and NDVI characteristics of the information, the decision tree was established to classify the information, and then the information of aquatic vegetation in Taihu Lake was extracted.
