摘要
根据黄土高原丘陵沟壑区土壤侵蚀定量遥感调查制图,对土壤侵蚀强度的定量、土壤侵蚀的地学特征与遥感影象特征分析、侵蚀因子匹配定量制图进行了论述。制图结果表明:土壤侵蚀的地学分析与影象特征分析相结合是判别土壤侵蚀类型和侵蚀强度,进行定量制图的关键;用彩红外航片可满足1:50 000土壤侵蚀调查制图的精度要求。
Based on soil erosion survey and mapping with remote sensing in hillly and gully regions of Loess Plateau, the quantity of soil erosion intensity, characteristic analysis of remote sensing image, and qnantitative mapping of erosion matched were dealed with in this paper. The mapping results showed that combining geology analysis of soil erosion with feature analysis of image was crux to judge soil erosion type and intensity,and to take quantitative mapping. Mapping with color infrared aerial photo may reach precision requirment of soil erosion survey and mapping with 1∶50000 scale.
