摘要
探讨在缺少实测和调查土壤侵蚀模数资料的地区 ,应用TM卫星图像和地形图 ,结合前人资料和野外典型调查 ,建立水土流失类型、强度与土地利用类型、植被覆盖度和地形坡度的相关关系 ,经遥感综合解译 ,编制水土流失现状图的技术方法。
The present paper makes an approach to the methodology of soil erosion mapping in the region lack of field observations by the use of TM satellite images and topographic map in combination with soil erosion type and intensity, correlation of vegetation cover rate with slope established by previous data and field typical investigation.
