land-use structure underwent drastic and profound changes.Supported by the software of ENVI 4.7 and ArcGIS 9.2

land-use changes in terms of changed areas

land-use regional variations and the matrix of transferring probability were calculated and analyzed using artificial supervised classification based on 2000 and 2006 TM remote sensing images and other data.The results show that land use structure of Luochuan County had changed greatly during the six-year time span.The orchard and construction land changed substantially and the newly developed area increased rapidly

with a recent depletion of grassland.The area of orchard nearly doubled and a considerable amount of cultivated land was transferred to construction land.The area of forest increased gradually.Regional land use variations and land-use transferring differed in the extent and scale.The increase of orchard come mainly from grassland and forest land

while woodland was mainly converted from grassland.A noteworthy amount of orchard and farmland was converted to each other.
