摘要
以湖北省为例,在传统目视解译方法的基础上对遥感调查方法做了改进.通过遥感影像的信息提取,获得区域土地利用类型和水土流失影响因子,在此基础上建立水土流失分级指标,并使用ARC-GIS强大的空间分析功能生成最后的结果.采用该方法能够及时掌握区域水土流失现状、水土保持治理、水土流失动态变化等信息.
The paper makes a case study of Hubei Province for a RS and GIS based water and soil loss investigation.It studies regional land use and affecting factors of soil and water loss,setting up grading index resorting to the powerful function in spatial analysis of ARCGIS and the field survey.The soil erosion remote sensing investigation is carried out,so that we keep the track of the present status of soil and water loss,soil and water conservation management and dynamic changes of soil and water loss of the region timely.
