Abstract: Based on the RS and GIS technologies,temporal and spatial dynamic on Land Use Change and Cover(LUCC) for 1987 and 1999 in Pingbian Miao Nationality Autonomous County of Yunnan Province was studied.The results showed that the land use pattern given priority to the forest land kept steady and had a small range of change from 1987 to 1999.The most active change was the decrease of the barren,which had averagely decreased by 3.77% per year within 12 years periods.Totally 49.3% of the barren became the farmland.The change of the farmland was consanguineously related to the altitude.The most significant change appeared at the altitude of 800-1500 m and the middle and high latitude regions upwards of 1500 m,where more barren became the farmland.Human activities were the main driving force of LUCC.
