Abstract:: Based on detailed survey data of land use from 1992 to 2001,using dynamic degree model,change of land use degree model and change of information entropy model,this paper analyzed the land use spatial-temporal changes and the change trend in Loess Plateau of Northern Shaanxi province.The conclusions were drawn as follows:(1) land use changed observably.Farmland and unused land reduced.Meantime,forest land,garden land,grassland,rural residential land and city and town land,traffic land and waters land increased.The synthetic dynamic degree of land use in Loess Plateau of Northern Shaanxi province is 0.83% per year.The conversion rate of Garden land is 35.10%,the biggest number of all land use types.(2) The spatial difference of land use change was obvious.The distribution of spatial difference was in reasonable agreement with physical geography subarea.The trend from north to south presented low-high-low-high.(3) The change of land use degree and information entropy indicated the alterative trend of land use.Both of the change showed that in the last 9 years the land use type was inordinate gradually.
