根据80年代和90年代两次卫星遥感普查资料，辽东山区土壤侵蚀面积有所削减，但幅度甚小，且部分地区开始出现强度和极强度侵蚀。成因主要为独特的地形地貌等自然条件及给山区生态环境带来严重破坏的人为经济活动。
According to the data of two satellite remote sensing surveys in the 1980s and 1990s, the area of soil erosion in Liaodong mountainous area has been reduced, but the magnitude is very small. In some areas, intensity and extreme erosion have begun to occur. The causes are mainly man-made economic activities such as unique topography and natural conditions, and serious damage to the mountainous ecological environment.
