The Dynamic Analyses of Coastal Land Use Patterns in Inner Lingdingyang,the Pearl River Estuary
【摘要】：正To satisfy the growing land demand from economic development, a large scale of land reclamation has been carried out in inner Lingdingyang area in recent years. As a result, the tidal flat and the water channels are narrowed, the frequency of flooding increased and the environment undermined. Guangzhou Marine Geological Survey (GMGS) conducted an integrated project for marine geo-environment geo-hazards survey in 2003. With the integration of multi-temporal remote sensing (using the images of 1977, 1978, 1988, 1996, and 2003), GIS spatial analyzing approach and GPS technique, as well as field data and other background data of the region, this research investigates the comprehensive characteristics and the drivers of coastal land use dynamics and shoreline changes in inner Lingdingyang area. It is revealed that the reclaimed coastal land was mainly for agriculture and aquaculture in early years, but now they have been converted to construction sites of harbors and industries, especially high-tech industry.
