| 摘 要： | 利用环境一号卫星 CCD影像，综合现场巡视情况，对2014年1—5月太湖梅梁湖水域的沉水植被区域进行分析与研究，分别取沉水植物、水华、地表植被与水体4个样本区域，对它们的光谱反射率曲线进行分析，得到沉水植物光谱反射率曲线相比其他样本区域独特的结论。并根据此特征，结合基于提取样本运行决策树的方法，以2014年5月1日为例，提取出了太湖梅梁湖水域沉水植物的分布区域与面积。

| Abstract: | Based on CCD images of Environment Ⅰsatellite and site conditions,researchers analyzed submerged plant area in Meil-iang Lake in Taihu Lake during January and May in 2014 Samples were collected in four different areas,submerged plant area,wa-ter bloom area,surface vegetation and water.Spectral reflectance curves showed that spectral reflectance curve of submerged plant was unique.Therefore,distribution area of submerged plant in Meiliang Lake in Taihu Lake was extracted. |
