In the region, more rainstorms, great R value of rainfall erosive agent, burning the grass on waste hills and conducting whole reclamation for soil preparation and afforestation and irrational activities of development and construction .

Based on the method and principle of the tracing in the source of mineralization material from the stable isotope, we use the sulfur isotopic indexes from Wunugetushan, Kenshan, Bainaimiao,Inner Mongolia, and Chengmenshan area in Jiangxi, and try to use the characteristics of sulfur isotopic composition (δ~(34)S) to determine the causes of geochemical anomalies.

Based on the measured data of soil nutrients and soil erosion, three afforestation methods, including controlled burning, full cultivation and bunch plantation, were compared .

By laboratory cultivating and experimental field examinning to the present soils at Pingguo Aluminum Mine, the covering meaterials for mine reclamation engineering is selected The covering plan taking tailing slurry as bottom bed and soil of bed of orebody added with ash as regenerated topsoil material is advance

However,the rate of mine reclamation in China is lower than 10 percent.
