Abstract
Researching dynamic variation of vegetation coverage has positive significance for vegetation restoration and ecological reconstruction. Landsat TM/ETM+ remote sensing data of the 2002, 2005, 2007, 2009 and 2011 was analyzed by ENVI and GIS technology, divided the vegetation coverage into 6 grades based on dimidiate pixel model, concluded the variation of ecological environment based on transfer matrix method, taked the Daliuta Mine as a case. The results indicated that average vegetation coverage in Daliuta Mine has increased integrally, and vegetation coverage changed from low, medium low and medium to medium and medium high, the vegetation coverage has somewhat. The dynamic monitoring of vegetation coverage can effectively reflect the variation of ecological environment in Daliuta Mine. This study provided a theoretical basis for the ecological reconstruction and sustainable development of Daliuta Mine.
