Tailings field is the land without transformation of industrial mining unavailable. With the exploitation of the mineral resources, the tailings rapid expansion, not only to invade and occupy a lot of land, and mining waste accumulation is a serious source of pollution. On the the tailings field of research and governance important for regional pollution control and ecological restoration, revegetation and ecological reconstruction of industrial and mining wasteland is the current ecology of an important field of research. Copper tailings is a class of high content of heavy metals, toxic plant growth habitat, pollution of the surrounding environment, destroying the ecosystem. How degraded ecosystems in such vegetation restoration and plant reclamation has become the environmental ecology research hotspot attracted the attention of researchers at home and abroad. Tongling, Anhui Province is China's famous medicinal plants Fengdan (Paeonia ostii) township, not only the superior quality of herbs, and the scale of production is the first in the country, particularly in the Phoenix Mountains region is most famous. Tongling is one of the important copper producing region, has a long history in smelting and, in particular, after the liberation of the process of the formation of a large number of large-scale mining tailings occupy a large area of ??land, which the large tailings (field) five kilometers tailings course, black Shahe the tailings field, the Tongguanshan tailings, the Phoenix Mountains tailings, Lion Rock tailings five, a total area of ??approximately 2.8 million m2. Local government in the recommendations of researchers actively support and called on local villagers in the tailings pond casing planted the Fengdan achieved good economic and ecological effects. Research, the situation of heavy metal pollution in Tongling City the copper tailing Fengdan planting base, analyze the content of heavy metals in soils and the presence of morphological changes and their impact on the quality of the phoenix paeonol, at the same time from the other hand, preliminary study Fengdan improved tailings soil ecosystem. The main findings are as follows: 1. Survey analysis of heavy metal pollution in Tongling City Paeonia ostii soil copper tailings, soil environmental quality standards based on national soil Cu content exceeded 4.36 to 14.43 times, Cd excessive levels of 3.67 to 3.86 times the background value; Yamashita control the content of heavy metal elements in soil samples as, Chen H M. et al CPI index the Integrated Pollution CPI calculation the cultivation Fengdan soil of heavy metals = 5.607, the performance of the heavy pollution . Chemical exists in the form of heavy metals in the copper tailing soil was extracted and analyzed, the results showed that the activation of heavy metal elements Fengdan effective Heavy Metals in the relative percentage, but Fengdan heavy metals the content of the element with the various chemical forms of the respective metal elements in the soil containing
