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 Meiliang Lake in Taihu Lake during January and May in 2014 Samples were collected in four different areas, submerged plant area, water 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.
