Based on the three sets of LUCC data(1985

1995and 2000)from the Environmental and Ecological Scientific Data Center of West China

spatial analysis with GIS and statistics methods were applied to analyze the quantitative change

transferring status

and transferring rate of land use types in Danjiang and Hanjiang river.The spatial distributions and the dynamic changes of land use were also studied in regard to different slopes.The results indicate that cultivated land

forest and grassland were the main land use types in the study area

accounting for more than 99%of the total area.From 1985to 2000

the areas of cultivated land

forest

architecture and water deceased and then increased

as the grass land showed the opposite trend.Cultivated land and architecture land increased 105.08km2 and 14.85km2 respectively

forest and grass land decreased 41.02km2 and 77.63km2 respectively during the fifteen years.In terms of slopes

the land use change mainly occurred on the lands with slopes from 5°to 35°

and the land with slope from 15°to 25°experienced the greatest change
