Wan’an County, Jiangxi Province, a rare mine for the small mines, built in 1985, mining, since the mine production is not normal, and the original mining process unreasonable, resulting in mining area formed a number of mining, mining surface bare, water and soil Serious loss. On the basis of comprehensive investigation on the current situation, characteristics and hazards of soil and water loss in rare earth mining area, the scope of prevention and control of the program is determined and the causes of soil erosion are analyzed. The potential hazards of soil erosion are evaluated and the management countermeasures are put forward. At the same time, Benefit analysis to explore.
