The Spatial-Temporal Changes of Land Use/Land Cover in the Upper Reaches of Min River from 1986 to 2000

Land use and land cover change research is one of the frontier and the hotspots in the global change research. We analyzed the spatial-temporal characteristics of land use and land cover changes in the upper reaches of Min River on the base of statistical data and using the Landsat TM and ETM data from 1986 to 2000. The results showed that land use and land cover changed remarkably during 1986 to 2000, especially between 1995 and 2000. There were no changes about water and unused land during 1986 to 1995. The conversion between land use and land cover types mostly happened among cropland, woodland and grassland. The woodland area decreased 3.526%; cropland, grassland, built-up land, water and unused land increased 0.352%, 1.575%, 0.003%, 1.537% and 0.161% respectively.
