Abstract: Due to the diversity of wetland ecosystem services, the imbalance of their spatial distribution and the selectivity of human use, the relations between wetland ecosystem services will have tradeoffs and mutual gain variations under the effects of anthropogenic and natural factors. Understanding the degree of concerns on the wetland ecosystem services from different beneficiaries is of great importance to formulate regional development and wetland protection policies and measures. In our study, we selected the Shuangtai Estuary National Reserve in Liaoning Province as the study region, and used the analytic hierarchy process (AHP) to pairwise compare different wetland ecosystem services, including substance production, flood control, carbon sequestration, climate regulation, gas regulation, creating land with silt, eliminating waves for revetment and leisure tourism at four levels of beneficiaries from local, provincial, national and global administrative areas. We also used the expert scoring method to grade those wetland ecosystem services from the four levels of beneficiaries. The results showed that the local beneficiaries mainly focused on substance production and eliminating waves for revetment, with weights of 0.2234 and 0.2154; provincial beneficiaries mainly focused on leisure tourism and climate regulation, with weights of 0.2740 and 0.2230; national beneficiaries mainly focused on climate regulation and the gas regulation, with weights of 0.2155 and 0.2150; global beneficiaries mainly focused on carbon sequestration and gas regulation, with weights of 0.2939 and 0.2161. Moreover, based on the different social attribute characteristics of different interviewees, such as age, income, education background and profession, our results showed that different beneficiaries with different social attributes focused on different wetland ecosystem services. These results can provide theoretical supports for the choice of the values of different ecosystem services and also for the tradeoffs among different beneficiaries in the future.
