Rare earths are important resources which are required by modern technology.The high economic benefits from rare earths mining that lead to seriously over exploitation,which causes the serious environmental problems and needs to be monitored for the purpose of protecting environment.Remote sensing as a macro observing method is good at land cover change detection.There are many different kinds of remote sensing data,has become a important change monitoring data base.In this study,spectral information is used to calculate the normalized difference vegetation index(NDVI),and the NDVI of estimation of vegetation coverage.the Landsat-TM/ETM+ and HJ-1/CCD data are used together to monitor the rare earths mining circumstances,including mining numbers,mining starting date,mining close date,mining type,mining areas,and the change of vegetation cover from 1988~2012at Dingnan,Jiangxi province.Through the use of HJ-1/CCD satellite data,shortening the period of field monitoring,reduce costs,and vegetation coverage index can direct response,mining area of variations provides the reference for the protection work of the study area.
