- Abstract:
- Based on the remote sensing data of Jiangxi Province, we used man computer interactive image processing methods to acquire the land use data in 2005, 2010, 2013. With the help of GIS and Ucinet software, the spatiotemporal variations of land use change were quantitatively analyzed, including land use change rate, land use transformation pattern and land use intensity. The results showed that: (1) the integrated dynamic degree of land use showed the decreasing tendency, during 2005—2013, the area of grassland, arable land and unutilized land decreased gradually, the area of construction land increased gradually, the water area increased during 2005—2010 and then decreased during 2010—2013, forest area decreased during 2005—2010 and then increased during 2010—2013; (2) since 2005, the land use interchange flowing between arable land, forest land and construction land had been dominant in the land use change of Jiangxi Province; in general, the density of the area of land use change decreased and the range of high density reduced, the hot area of land use transformation distributed in patches or dots; (3) in general, the land use intensity in Jiangxi Province showed increasing tendency during 2005—2013, and the gap narrowed between the area of high land use intensity and the area of low land use intensity. Affected by the central policy, the Poyang Lake ring area and Gannan area become the areas of obviously high land use intensity.
