| 摘 要： | 针对环境卫星 CCD 影像,结合影像质量评价、专题制图、土地利用/覆被解译以及常用植被指数构建,以青海湖区域为例,与Landsat TM影像进行比对研究。结果表明,在与TM影像质量评价参数比较中,TM影像较优,而环境卫星影像具有很大的改善空间;在对地物判译中,环境卫星影像色彩稍暗淡,但对大多数地物解译判读的边界更清晰;环境卫星覆盖度大,区域制图的优势非常明显;生态监测定量遥感常用的植被指数比较中两种数据大致相同。

| Abstract: | The area of Qinghaihu lake was selected as the typical area for the research of HJ-CCD image and Landsat TM image. The statistical comparison of image quality was that TM image with much better information capacity, texture, etc. However, the image quality of HJ-CCD can be improved greatly by image enhancement processing. For the ability of thematic mapping and monitoring land use/cover change, HJ-CCD image was better. HJ-CCD image had the same ability in constructing usual vegetation index of ecological monitoring as TM image. |
