Abstract:Based on Remote Sensing and Geographic Information System,it acquired land-use datum of Xiaojiang Basin in 1987,1995 and 2000.It presented land use change during 1987~2000,such as land-use change range and rate,conversion among land-use types and development trend of land-use pattern in 2015 by using Markov Probability Model.The studying findings were as following: farmland,woodland,town and resident land increased quickly from 1987 to 2000,especially farmland;farmland increased from 345.1 km~2 in 1987 to 398.7 km~2 in 2000.The land use change rate was rapid and the annual change rate reached to 0.49%.For each land-use type,the change rate of town and resident land was largest among all land-use types,and it was 3.52%;and next were farmland and water land.The increased farmland mainly came from woodland,grassland and water land;and some woodland was degenerated to grassland,accounting for 12.64%,except for woodland converting to farmland.Grassland and barren land changed a little.By 2015,area and proportion of farmland,woodland,water land,town and resident land will increase,and the area and proportion of grassland and barren land will decrease.
