Abstract—Land use and land cover change research is one of the Bergsma, 1998; Shen et al., 2003; Zhao et al. 2004). 3S (RS, frontier and the hotspots in the global change research. We GIS & GPS) techniques provided the reliable support to analyzed the spatial-temporal characteristics of land use and land analyse for us. Satellite remote sensing played a key cover changes in the upper reaches of Min River on the base of role in providing detailed information about large-scale statistical data and using the Landsat TM and ETM data from deforestation (Skole et al., 1994) and the spatial distribution 1986 to 2000. The results showed that land use and land cover and extent of land use changes(Roy et al., 2001). The GIS changed remarkably during 1986 to 2000, especially between approach for land cover dynamics was a widely accepted tool 1995 and 2000. There were no changes about water and unused because of its ability to examine spatially referenced objects land during 1986 to 1995. The conversion between land use and over time paring time-series maps prepared from land cover types mostly happened
