Abstract: The shoreline is one of the most important land resources and its unreasonable utilization could lead to severe pollution and ecological damage.Based on the remote sensing images of different periods, the spatial distribution characteristics and the attribute information of Guangxi shoreline are identified and extracted, according to the waterline, adjacent type of the land cover and land use, texture characteristics and so on. After analyzing spatial distribution, reclamation and attribution of shoreline, the driving force of shoreline change is studied. In the end, the conclusions are achieved: the length of shoreline increases about 102.86 kilometers in thirteen years, and the period of major shoreline changes occurs between 2005 and 2010; The natural shoreline is becoming shorter and shorter, on the contrary, the manual shoreline is getting longer and longer. On the whole, the building of harbour, wharf and the industrical zone are the main causes of the reclamation. The area of reclamation in recent 13 years is about 66.74 kilometers. The growth pole of reclamation lies in Qin-nan District of Qinzhou city, and Gangkou District of Fangcheng city. The shoreline type is rich in natural resources. The biological shoreline and the muddy shoreline are the main types among the natural shoreline, and the cultivtion shoreline is the most outstanding type of the manual shoreline. The results of the research will have great significance in the development of the shoreline resources, protection of the biological environment and the reasonable distriboution of the karbour.
