Abstract：In this paper, the sea reclamation process in partial areas of Liaoning province is monitored and the wetland and reclamation area transfer relationship in these areas is analyzed based on the data of wide-band imaging spectrometer on Tiangong-2 in 2016 and the historical remote sensing data of Landsat-5 in 1986, 1996 and 2006.The results indicate that the reclamation area kept increasing from 1986 to 2016 with the most increment as much as 29499.93 hectares in the last ten years.The beach wetland was occupied by the reclamation area with a stable speed in each period, while the coastal waters with a rising rate and the salt marsh wetland with a declining rate year by year. The wetland and reclamation area transfer relationship is different period. Further trade-off between the ecological service value loss and economic value increment of different transfer types is of great guiding significance for scientific sea reclamation programme and practice.
