Abstract: Wetland plays an important role in ecological protection and social development. Scientific and rational evaluation of the values of wetland ecosystem service is the basis of protection and sustainable utilization of wetland resources. How to scientifically and effectively assess the wetland ecosystem gross ecosystem product (GEP) and make it into the national GDP accounting system are the focus of the scientific community and government departments. In this study, the accounting framework of wetland ecosystem GEP was constructed. Based on multi-source data and from the aspects of function and value, the accounting of wetland GEP in Fuzhou City was carried out. The results showed that the GEP of wetland ecosystem in Fuzhou City was 239.23 billion yuan in 2015. Such value mainly came from the ecological regulation service value (157.869 billion yuan), which accounted for 66.0% of the total and was about 2.2 and 15.6 times of the product supply service value and cultural service value. Among the ecological regulation services of wetlands, hydrodynamic regulation service and climate regulation service were the highest. Together, they accounted for 82.9% of the ecological regulation service value. The ecological regulation value per unit area of wetland in Fuzhou City was 1347.8 thousand yuan·hm-2, which was higher than the mean level of the whole country. In the districts and counties of Fuzhou City, the value of wetland ecosystem in Minqing County was the largest, about 88.83 billion yuan, accounting for 40.1% of the total value of product supply and ecological regulation. In terms of types, coastal wetlands in Fuzhou City had the largest function of ecological regulation services, which was about 2.5 times of that of river wetlands and constructed wetlands. The accounting of GEP of wetland ecosystem in Fuzhou City is an important practice for the conviction of “lucid waters and lush mountains are invaluable assets”, which would provide technical support for guiding local government to scientifically manage wetland ecosystem.
