There are rare earth mines in Longnan, Jiangxi Provence, South China as study object, where the investigation, sampling have been carried out and all samples were tested and analyzed. The results supported that key problems of polluted soil restoration in rare earth mining area are soil bad acidification and serious NH4+-N,NO3--N,NO2--N pollution.
