Abstract: This paper discussed on survey research methods of damaged ecosystem of tailings pool area in typical polymetallic mine is discussed.According to trace elements analysis,chemical phases analysis and appraisal of heavy minerals,analysis of major elements and X-ray powder diffraction,it can be studied that includes material composition,the contents and distribution of pollution elements,chemical and mineral occurrence state of pollution elements for tailings pool(patch).Transmission path pollutants for tailings pool(patch) was studied by means of ion content and pH analysis for water in tailings pool area,heavy metal content analysis of reclaimed soil-plant,landscape structure on-site investigation and remote sensing interpretation etc.It can be provided scientific basis to restoration of damaged ecosystem and land reclamation for the polymetallic mines.
