Temporal and Spatial Analysis of Coastline Changes in the Bohai Rim Based on RS and GIS

Remote sensing and GIS technology was adopted to monitor temporal and spatial distribution of continental coastline in the Bohai Rim from 2000 to 2008. Moreover, this paper has analyzed the fractal dimension change of coastline. Both the length and fractal dimension of the coastline in Bohai Rim increased from 2000 to 2008, which were mainly caused by human disturbances. Regional difference of coastline change was significant, especially the length change intensity of coastlines in Tianjin City and Hebei Province were relatively higher. Expansion of port and dock, construction of port-surrounding industrial park as well as development of breeding pond and saltworks were the main artificial disturbance factors for change of coastline in the Bohai Rim.
