with the aid of the RS/GIS technology characteristics of land use change from 1991 to 2000 (divided two phases) in Xinjian County of Jiangxi Province were analyzed quantitatively, using a land use change index model. Results indicated that arable land decreased by 2199.181 hm² and unused land by 1290.016 hm², while forest land increased by 1655.375 hm² and construction land by 1880.467 hm², but grassland and water surface remained more or less the same. In terms of single land use change dynamic degree the six land use types were in an order of construction land > unused land > forest land > arable land > grassland and water surface. And the dynamic degree of integrative land use change from 1991 to 2000 in Xinjian County Was 0.165%.Land use intensity integrative index was 243.687, 244.084, and 244.868 in 1991, 1996, and 2000, respectively, showing an ascending trend. In terms of land use change spatial dynamic degree construction land Was the hiighest, and followed by unused land, and grass land, and arable land the lowest. The rising or falling trend for single land use change from 1991 to 2000 Was analyzed, showing spatial dynamic degree for integrative land use change Was lower during the latter phase(1996-2000)than the former(1991-1996), and the change of regional land use change Was shifting slowly from both-way to single-way.
