Abstract: The TM imageries of1986,1996and2000are interpretated to study the land use change in Haikou.The land use conversion matrix uncovers the law that the cultivated land,forestland,foreshore and unused land was converted into land for urban,rural housing and construction purposes.The fractal dimension of the forestland and water bodies lowers because of the human induced disturbance.That of the cultivated land decreases with the conversion into the construction land.The urban land concentrates with the decrement of the patches and the incre ment of the acreage.But the rural land disperses because of the increment of the rural patches.The main driv ing forces of the land use structural change are the urban sprawl and the rural extension with rapid urbanization and rural settlement extension.The land use extent in Haikou tends to be deepened.
