| 摘 要： | 以黄河流域甘肃片水土保持遥感普查为例,分析了土壤侵蚀六项主要影响因子:侵蚀类型、侵蚀强度、地表组成、地貌类型、植被覆盖及地面坡度。通过研究各因子在TM影像上的分布、形状、纹理等识别特征,探讨了水土保持影响因子在遥感判读中的信息提取方法。并具体应用到2000年黄河流域甘肃片遥感普查数字化工作中,提出了各因子遥感判读特征分类系统。

| Abstract: | The study content of this paper is the remote sensing survey of the soil conservation in the part of Yellow River Basin in Gansu province. Six main influential factors are analyzed. They are erosion types, erosion intensities, land surface components, topographic types, vegetation covers. To analyze the distributing shape, texture and identification features of these factors in the Landsat TM images, the information extraction methods of these factors from remote sensing interpretation are discussed. An application is used on the digital works of the Remote Sensing survey in the part of Yellow River Basin in Gansu. |
