摘　　要：影像图谱特征包括光谱特征和图型结构特征两个方面。基于Landsat 8,GF-1,ZY-3和SPOT-5等光学卫星遥感影像,本研究分析了河流/沟渠、水库、湖泊/坑塘、盐田、养殖区和近岸海域等海岸带水体的影像图谱特征,结果表明:不同类型海岸带水体的光谱特征很相似,但它们的图型结构特征差别较大,结合两者则可较容易地提取出各类海岸带水体信息。研究结果可为海岸带区域的水体遥感监测提供技术支撑,进而服务于海岸带资源环境综合调查。The image map features consist of two aspects：spectral features and graph structure features.The image map features of the coastal waters such as rivers/ditches,reservoirs,lakes/ponds,salt fields,aquaculture areas and inshore waters are analyzed based on the optical satellite remote sensing images from Landsat-8,GF-1,ZY-3and SPOT-5.The results show that the spectral features of all of the coastal waters are similar,but the graph structure features of them differ significantly,and that by combining the former with the latter,the information about the waters in different coastal zones can be easily extracted.These results may provide technical supports for the water remote sensing monitoring in the coastal zones and hence give service to the comprehensive surveys of resources and environments in the coastal zones.
