Sea Areas Reclamation and Coastline Change Monitoring by Remote Sensing in Coastal Zone of Liaoning in China

Aimed to monitor spatial pattern of sea areas reclamation in Liaoning province. Series satellite remote sensing images obtained from 1990 to 2010 were employed to monitor sea areas reclamation and coastline change in coastal zone of Liaoning. Some spatial index was established to describe sea areas reclamation and coastline change by geographical information system, respectively. The results are as follow: Spatial index based on geographical information system are suitable to assess spatial pattern of sea areas reclamation and coastline change. The sea areas reclamation in coastal zone of Liaoning is 35,720.98 hm(2) from 1990 to 2010. The sea areas reclamation intension is high in Panjin and Jinzhou with reclamation intension index above 90.0 hm(2)/km, but low in Huludao, Yingkou and Dalian with reclamation intension index below 20.0 hm(2)/km. Length of coastline in Liaoning increased and its tortuosity ascend over last 20 years. The increment is 30% in some regions as Jinzhou and Panjin. Exploitation of coastline cause the growth of the length of artificial coastline (dams, bulwark, e.g.), while natural coast line (rock coastline, sandy coastline and muddy coastline) is compressed.
