基于高分辨率遥感影像的水土流失监测方法研究

Monitoring Method of Soil and Water Loss Based on High Resolution Remote Sensing Images

以葫芦岛市为研究对象,根据区域土地利用类型和水土流失影响因子建立水土流失分级指标,运用RS和GIS技术获取水土流失影响因子信息并进行空间叠加分析,实现对区域水土流失状况进行调查、分析和管理,具有快速、准确、客观、经济等优点。该研究方法能够及时掌握区域水土流失现状、水土保持治理状况、水土流失动态变化等信息,为建立水土流失动态监测数据库、实现对水土流失进行动态监测奠定基础,从而有效地促进水土保持工作的顺利开展。

It achieves the survey,analysis and management of regional status of soil and water loss by taking Huludao City as a research object,establishing gradation indexes of soil and water loss based on regional land use types and affecting factors of soil and water loss,obtaining affecting factors of soil and water loss by using RS and GIS technique for spatial overlay analysis. This method has advantages of quick,accurate,objective and economic. It can timely control the information of regional present situation of soil and water loss,statement of soil and water conservation treatment and dynamic variation of soil and water loss and lay a foundation for establishing a dynamic monitoring data bank of soil and water loss and achieving dynamic monitoring,so as to effectively promote the smooth development of soil and water conservation.
