Abstract:
Taking Jiangsu province as an example,based on shapefile data of 2000 and 2010 of Jiangsu and with the technology of GIS,the paper revealed the characteristics of the land use change from the range and rate of land use change,the direction of land use transformation,and analyzed the driving factors of land use change by using socioeconomic data. The results showed that:(1)During 2000 and 2010,the expansion of construction land was most evident,the area of water,especially the reservoir and pond increased significantly. However,a mass of cultivated land reduced. From the single dynamic degree of land use,bare land increased rapidly and changed dramatically.(2)From transition matrix of the land use types,cultivated land was always an important source that converted to other land types such as construction land,reservoir and pond land;the source of construction land came from the conversion of cultivated land,which is the most important part,then water,forest land and grassland;the area of reservoir and pond increased from cultivated land,tidal-flat,grassland,construction land.(3)The driving mechanism of land use change in Jiangsu province can attribute to many factors such as the rapid population growth,economic development,industrial structure and government policy.
