| Abstract: | Yancheng coastal wetlands are facing unprecedented pressure because of the expansion of Yangtze River Delta and the national strategy of Jiangsu coastal exploitation. The paper used multi-methods to evaluate the economic values of the selected 8 ecosystem services based on land use changes, which were attracted from Landsat remote sensing data. Results showed that the total economic values were enormous, 68.3 billion RMB on average. Among them, the value of original wetlands made the greatest contribution. It was about 31 times the value of artificial wetlands and non-wetlands as a conservative estimation since most of bequest and existence values were not included. Indirect use values was about 6.5 times of direct use values. The total values varied with time and the net loss was 2.769 billion RMB in recent 20 years. There was an obvious degradation tendency of original wetlands shifting to other land uses for different economic benefits during 1987-2007, which contributed to the increase of the direct use values and the decline of indirect use values and optional values. |
