Abstract
Ion-absorbing Type Rare Earths Ore mining caused a series of environmental problems. The thesis focused on the study of the district for heavy rare earth in Longnan County, Jiangxi Province, South China. It examined characteristics of spatial-temporal variation for vegetation fraction (vf) in study area by 10 images of Landsat TM and ETM+ during 1988 to 2009. The results supported that: (1) there were spatial-temporal differences of vf in each mineral district and the areas for medium to high vf dominated in mineral districts, but low vf distributed on concentrated mining districts; (2) dynamic variation for vf differentiated in each mining area each stage, no change areas dominated in mineral districts, but negative change areas only distributed on concentrated mining districts; (3) the history of production, various technologies and preventive measures were the main factors caused spatial-temporal differences of vf in mineral districts.
