| 摘 要： | 以江苏东台东部淤泥质潮滩为例，在野外滩面调查的基础上，统计并分析了典型样点光谱特征，建立了不同地物判别函数以区分淤泥质潮滩地物。在判别分析基础上，总结淤泥质潮滩各类地物的光谱特征，建立判别规则库，以辅助识别淤泥质潮滩地物。实践表明，该方法可快速从Landsat7 ETM 影像中提取出淤泥质潮滩地物信息。

| Abstract: | Taking the Jiangsu tidal flat as an example and based on the field investigation on the tidal flat, the statistical analysis of spectral characteristics at typical sampling points was made and the discriminant functions of different ground objects were then established to distinguish between different ground objects on the tidal flat. Based on the discriminant analysis results, the spectral characteristics of different ground objects on the tidal flat were summarized, and the discriminating rule databank was establiched to support the identification of ground objects on the tidal flat. It is shown from the practical application that the remote sensing method can be used to quickly extract the tidal flat ground object informations from the landsat 7 ETM+ images. |
