LUCC AND ITS DRIVING FORCES IN MOUNTAIN BASINS OF YUNNAN PROVINCE:A CASE STUDY IN BAOSHAN BASIN

The land-use change and its driving factors in Baoshan basin from 1980 to 2000 have been analyzed based on the ARCGIS software.The results showed that:the general change ratio of LUCC was 0.17% each year from 1980 to 1995,and which increased obviously after 1995.In general,the paddy and wood land decreased when the dry land and construction land increased,especially between 1995 to 2000;some paddy in the basin were transformed to construction land,while farmland,grass land and wood land transformed between each other.For the driving factors,the landform is fundamental,under the control of the basin spatial limitation,population increasing,economic developing and policy regulation became the dominant humanity factors that drive the land use change in the study area,and which may put more pressure on the land.
