Abstract

On the basis of meteorological data of mining area in Sunite County and the surrounding prairie soil heavy metal content in a grassland mining area,analysis of drift potential and soil heavy metal pollution characteristics of the grassland mining area was conducted.The results showed that the heavy metal pollution in the investigation area was mainly concentrated on the lower wind direction,which is the dominant wind direction centered on the tailing storehouse.Sunite County is an area severely affected by erosions.The tailings and slag sediment cover measures shall be strengthened,prevention and control of wind and water erosion intensified and their effects in grassland soil heavy metal pollution reduced.Windbreaks and sand barriers shall be built to check the potential wind sand.Measures for ecological restoration and restoration of damaged ecosystems shall be taken.According to the regional characteristics,suggestions are put forward to ensure the healthy development of the ecologocal system and protect the health and safety of the local people and wildlife as well.

Key words： grassland mining area; heavy metal pollution; ecological restoration
