滦河流域从1990年就被列为国家级水土流失重点防治区，国家在水土流失治理方面进行了大力投入。进入21世纪，通过大规模的治理，流域水土流失得到了有效遏止，生态环境明显好转。与此同时，国家在该区域开展了多次土壤侵蚀遥感调查，调查结果在时间上形成序列，客观反映了流域的水土流失状况及其变化趋势。在历次土壤侵蚀调查结果的基础上，对滦河流域从1984～2008年近三个年代的土壤侵蚀时空变化进行分析，确定了流域内水土流失强度在空间和等级的变化情况。

Since 1990 Luanhe River Basin was listed as national key governance areas , the national government invested vigorously in soil and water loss controlling .Entering twenty-first century and through the large -scale management , watershed soil erosion was curbed effectively , and the ecological environment was improved significantly .At the same time , the national government carried out further investigations on regional soil erosion , which formed sequence at the time, and reflected the status and changing trend of water-shed soil erosion objectively .Based on the existing regional investigation results of the soil erosion intensity from 1984 to 2008 , the spatial and temporary changes of soil erosion are analyzed over the past three periods , identifying the soil and water loss intensity in space and grade changes .
