流域地表生态信息的卫星遥感图像处理技术

Remote Sensing Image Processing Technique on Ground Surface Eco-Environment Information in the River Valley

以福建省九龙江流域为例 ,利用计算机技术和遥感 -GIS工具软件 ,探讨利用多源卫星遥感影像获取流域地表环境信息的图像处理与分析技术 ,列举卫星遥感可获取的流域地表生态环境专题信息。重点分析利用遥感 -GIS界定流域范围的方法、流域地表覆盖状况和植被覆盖密度的卫星遥感影像处理方法。

With the Jiulong River valley as an example, using computer techniques and remote sensing (RS) and geographical information system (GIS) tools, the image process and analysis techniques were explored on river-valley surface eco-environmental information obtained from multi-source satellite RS images. The river-valley surface eco-environment themes available from satellite RS were listed. The focuses were on the methods to determine river valley scopes, surface coverage situations and vegetation coverage density, by integrated RS and GIS. =
