Abstract:

The effect of the sea reclamation projects on the offshore ecosystem was the focus which was paid wide attention by the field of ecology and ecological economics. Two kinds of methods were used in this article. Method I was market value method and surrogate market method, such as market value method, shadow engineering method, carbontaxes method, alternative cost method, and resultchecking method. Method II was contingent valuation method. It assessed the sea reclamation projects’ loss of ecological environment value from the angle of the tidal wetlands ecosystem services, which chose the seaside buildingarea of Lianyungang and the coastal buildingarea of Tongzhou as typical cases. The results showed:(1)The annual losses of the two typical cases with Method I was 0818 2×108 and 0696 2×108 Yuan RMB respectively.(2)Method II was 1273 9×108 and 1186 0×108 Yuan RMB respectively.(3)Results of two methods’ which were used as the ecological environment losses interval could improve the accuracy of the assessment. This research could supply references for the formulating of the sea reclamation projects’ ecological compensation standard and ecological compensation policy
