- Abstract:
-
Taking Dongguan City as the study area and applying satellite images of the Landsat TM/ETM+ in five different periods, including 10 December, 1988, 30 Decemember, 1995, 22 December, 1998, 7 Novemebr, 2002 and 23 November, 2005, we discussed characteristics of land use changes from four aspects including the amount change, change velocity, gravity migration and spatial differentiation. The main results are as follows:(1)during 1988—2005, land use change was indicated by decreasing cultivated land and expanding urban land because a great amount of cultivated land changed into urban land. Rapid expansion of urban land and huge loss of cultivated land are main features of land use change in the study area. (2)Changes also are represented by characteristics of migration of land use critical center and spatial autocorrelation of land use: critical center migration directions of agricultural land are generally opposite to that of urban land, and spatial autocorrelation of cultivated land is reducing and that of urban land is enhancing.
