Abstract:: The land-use information was extracted from the Landsat MSS image of the year 1975 and the Landsat TM images of the year 1986,1997 and 2006 by the method of automatic classification and visual interpretation.The quantity,rate,range,and spatial distribution feature of land use change was analyzed using GIS analysis module and ERDAS statistics analysis from 1975 to 1986,from 1986 to 1997,from 1997 to 2006.The results indicated that the cultivated land firstly increased and then decreased and on the contrary of grass and forest land.Unutilized land decreased on the whole except some small fluctuation in the middle.The transition of land use type was consistent at the early and middle stage.However,transition among the land use type was more intense in the later period than that of the former period.Cultivated land,grassland,unutilized and waste land were the dominant land-use change type and the transformation mainly happened among these land use types.
