Abstract:Based on the technology of remote sensing and geographic information system, land use data-base of a study area in the year of 1985 and 2005 was acquired. By the analysis of land use changes, the result shows that (1) from 1985 to 2005, among eight land use types, the area of agricultural land changes most, it decreases 2 048 km2, at a percentage of 31.4%; (2) By the main driving force of sea reclamation, the area of mainland coastline displacement is 370 km2, and East Guangdong,West Guangdong and the Zhujiang(Pearl) River Estuary occupy 12.6%, 31.2% and 56.2% respectively; (3) the area of construction land in the coastal regions of Zhuhai, Guangzhou, Shenzhen, the Daya Bay ,Shanwei and Shantou expands more than 10 times; (4) great changes have taken placed of land use in the area of Guangdong coastal zone and islands, and the land use type change direction and dynamic change degree of land use have significant spatial heterogeneity, the total integrated change degree of the study area is 24.2%, and in East Guangdong,West Guangdong and Zhujiang(Pearl) River Estuary regions are 15.6%, 22.8% and 28.2% respectively. A scientific basis can be provided for the sustainable use and management of ocastal land and marine resources.
Keywords:Guangdong Province  China  coastal zone  land use change  sea reclamation  transfer matrix  dynamic change degree
